Video Transcript for Redline 1/2 Inch Metal Loom Clamp Review

Today in this Old Trailer, we're going to review and install the Redline Metal Loom Clamp, part number A0500. The Redline Metal Loom Clamp is a solid band that goes all the way around with two pre-drilled holes, then has a coating that will help protect the wire once you squeeze it down and secure it. Slide the clamp on, close down, and I'm going to use my self tapping screw to secure it. That will do it for the review and install of the Redline half inch Metal Loom Clamp, part number A0500 on this Old Trailer. .

Metal Loom Clamp - 1/2" - A0500

Average Customer Rating:  4.8 out of 5 stars   (89 Customer Reviews)


Good quality. I used self- tapping screws to secure wire to trailer frame.


Worked very well in my 2015 Siena and rides very stable after installation! Very good product quality!


Nice quality.


I received my wiring harness and other components on the day in which they were promised for delivery. I had already viewed one of your posted videos on how to re-wire a utility trailer so I promptly installed the wiring harness and connected it to the lights which I had already mounted. Everything worked great! This was the first time I had re-wired a trailer and was initially apprehensive about doing the job myself. Your video made the difference! I have marked your website URL for future reference. You will be my "go to" site for trailer accessories and information.


Skip the zip tie and don’t be a hack


Used these clamps to secure the brake lines on a disc brake conversion. Worked great!


Brake assy. easy install.. Great ! I did not use the cut washers. Used thread lock instead. With cut washer & nut combined not enough thread bite on brake stud. Loom clamps & clips worked great. Used 10 gauge wire for brakes as your suggestion. Trailer had small gauge wire. Looked like #14 or #16 gauge. It was fried ! Had to order type 11 circuit breakers one 30amp. & one 40amp. Bad breakaway switch also replaced. Some one missed wired wiring. Had axels flipped. Thanks for wiring diagrams on your sight.. Travel trailer had a major melt down. Did not catch fire but some wood under side was burnt. Had to trace all wiring to see any further damage. Just only on brake side was the problem. Now my brake system is back to working. Brake control working now ! .That's what led me to know something was wrong. Thank you for your web sight. And thank your staff for their professional work. Their experience shows it. Your friend John R.


Exactly what I needed to complete my in stallation


Worked as advertised. Good fit for protective cable carrying trailer wiring which was a 3/8 diameter. I used 1/4" stainless steel bolts with locking nuts to secure the A0500 to trailer frame.


Perfect for installing Firestone Coil-Rite Air Helper Springs!


I used these clamps to replace the very rusted set on my trailer. I was able to fit a 14/6 cable with a 1/2" dia. protective plastic loom, and a brake wire pair into them. It was a tight fit, but they are holding securely. Great price and service from etrailer.


Good quality. Should be pre-bent into position because you'll be under the car/truck when you install it. These will hold your brake controller cable running forward securely. I used a combination of these clamps and zip ties.


All items in the order for trailer wiring components were exactly what I ordered and all items were delivered promptly. Good communication from Etrailer with reasonable prices, and FREE SHIPPING!! Nice.


I am glad I came upon this site. The staff is friendly courteous and helpful.

Since I live in Canada it is a big problem if I had to send items back across the border to etrailer if the items were not what I thought they were. The short videos that etrailer provides with each product is extremely helpful in determining to purchase or not. Thank you for that feature. Knowing a little about video production and the costs associated with that, it must cost etrailer a pile to give us (the consumers) what appears to be a simple addition on their site

Thanks again guys/gals


I bought these 1/2" to hold the corrugated plastic wire loom in place down the undersides of the trailer. They worked ok, but they did smash it down a bit. That's ok for this installation as there was plenty of room for wires, but be aware of the tight fit.


good product.....puts just the right amount of tension of the new four foot trailer harness I purchased at the same time. Installation looks very professional.


Worked well to secure my 6 wire trailer harness to the tongue.


installatiin was a snap with the video as a guide. The only problem I encountered was not fitting very well under the dash with my 6'4" frame.


Great product at a great price. I was securing battery cables on a race car when I ran out of clamps. I found e-trailer on line and ordered the parts on a Sunday night. Parts were delivered to my door on a Wed! I will order from e-trailer again, great timely delivery.


Product worked as advertised, however, the eye holes are a bit of a small diameter. I had to drill them out a bit to enlarge them for use on my trailer wiring. Otherwise, the came exactly as purchased. Thanks


I've made 2 purchases from in the past 3 weeks. Shipping was fast, the price was competitive and all items purchased were as stated in the descriptions. This is my go to site for any of my future needs.


Worked well for connecting trailer harness to trailer, good quality.


It's a clamp, what more can I say.

After a year everything is still working great. Love the products purchased and if Im in the need for more trailer supplies etrailer is the place for me.
William B - 04/09/2019


Simple and fit the 7 pin round cord.


All of the products I ordered were what I expected in quality from I have purchased from them many years past and that is why I continue to do so.

  • Wire Loom Clamp Recommendation for Boat Trailer
    We may not have exactly what you are looking for, but we do carry wire loom clamps like the # A0500 which you could use to secure the wiring of your trailer.
    view full answer...
  • What Type of Steel is Used in the Metal Loom Clamp A0500
    The wire loom part # A0500 is a zinc-coated steel. The zinc coating fights rust to prevent corrosion.
    view full answer...
  • What Gauge Wire Can the 3/8 Inch Wire Loom Hold?
    3 gauge wire is about 0.229 inches in diameter, so Wire Loom 3/8" Diameter like # 39035 will give it enough space for safety without further restricting the wire for heat dispersion. It will also avoid pinching or crimping the wire. You can use the Metal Loom Clamp - 1/2" # A0500 to secure it if desired. Technically this loom could hold up to 00 gauge wire (0.365 inches diameter).

  • Suggested Frame Clips to Secure Rubber Brake Lines on Saltwater Boat Trailer
    If your boat trailer has a frame design that will directly accept the clip-in-place Redline # 464600 frame clips then this will be your easiest installation. We do also offer 1/2-inch metal loom clamp # A0500 from Redline that has plated steel construction and a rubber sleeve to prevent friction damage to the wire or tubing secured in it. The enamel-finish clips # 464600 could still be spray-painted with an additional coating of paint for extra protection from corrosion, and this could...

  • Wire Loom Clamp To Use with Wire Loom, 3/8" Diameter 39035
    The outer diameter of the 3/8 inch inner diameter wire loom part # 39035 that you referenced is 1/2 inch. So for clamps you'd want the 1/2 inch clamps part # A0500.
    view full answer...
  • Frame Clip Size and Styles Available
    The height of the Wire Frame Clip, item # 464600, is 1-1/2 inches, width is 1/2 inch, width for wire capacity is 3/8 inch and the frame depth is 5/16 of an inch. Constructed of spring steel and has a black enamel finish. Metal Looms are also available and we have the 1/2 inch, item # A0500, and the 1/4 inch, item # A0250, which are installed usually with self tapping screws.

  • Clips and Clamps to Attach Wires and Wiring Harnesses to the Bottom of a Trailer Frame
    There are many ways you can secure wires to a trailer. I would not recommend the use of tape as it will wear out quickly when exposed to the elements. Soldering is also not recommended because it is a more permanent method and you may need to change wires or move them in the future the hot solder would also melt the coating on the wiring, causing a short. If you can find some large enough, wire ties could be a simple solution. We have several clamps and clips that could work for this application....

  • Screws to Use with the Wire Loom Clamp part # A0500
    You would want to use some self-tapping screws like the part # FA1131822. These would not require you drill a pilot hole. Just line the screw up where you want it through the Loom part # A0500 and let the drill bit end of the screw drill the needed hole and the threads will pull it through and secure it.

  • Will the 1/2 Inch Metal Loom Clamps Work On a 5/16 Inch Frame Rail
    Yes, the Metal Loom Clamp part # A0500 will work on a trailer frame that is 5/16" thick. The Metal Loom Clamp will actually work on pretty much any frame thickness but you will need to make note of the size screw used. I recommend the Hex Screw part # 101131802 for a 5/16" thick frame as it is 1/2" long. The Wire Loom part # 459075 can then be added to protect your wiring. I have attached a list of our other wiring accessories for you below as well.

  • Wire Loom Clamp/Clip Recommendations for 4-Way Wiring.
    Based on our customer reviews it looks like the Wire Frame Clip # CE16867A that you referenced has better reviews than the Wire Frame Clip # 464600. Either one should work fine, but if it were me I would go with the # CE16867A between those two. Another option is the Metal Loom Clamp # A0500. You will need to provide some self tapping screws but this is the loom clamp that our installers here at etrailer use the most. These clamps are rubber coated to protect the wires and since they screw...

  • Availability of Wiring Clips to Attach to I-Beam on EZ Loader Boat Trailer
    The CE Smith Trailer Wiring Clips # CE16867A referenced in your question will fit around edges that are up to 5/32 inches thick. I am not sure how thick the I-beam is on your EZ Loader Boat Trailer but we do have the slightly larger # 464600 Clip that will work with a frame thickness of up to 5/16 of an inch. I recommend simply measuring the thickness on the beam to see if one of these options will work. If the I-beam is too thick for either of these options then your best bet will be...

  • Compatibility Of 1/2 Inch Loom Clamps With 3/8 Inch Loom
    Yes, you can use Metal Loom Clamp - 1/2" # A0500 with Wire Loom 3/8" Diameter # 39035. It will secure the loom to your frame but it will not clamp tightly around it. If you want a tight fit at the clamps you can use 3/4" x 60' Electrical Tape to close the loom at that location and make it your desired thickness for clamping. If you want a perfect fit, I recommend the Wire Loom, 1/2" Diameter (per Foot) # 459075-1.

  • Recommended Installation Screws for 1/2 Inch Metal Loom Clamp # A0500
    For the Metal Loom # A0500 you will want to use the self-tapping screws like the part # FA1131822. The nice thing about this screw is that it doesn't require a pilot hole, just line it up and let the drill bit end of the screw do the work for you. This threaded screw will secure your loom clamp securely on your trailer. I have linked the above mentioned products to this page for your purchasing convenience.

  • Replacement Wire Loom to Secure RV Slide-Out Wiring
    Thanks for the photo, that was a huge help! You're needing 1/2 inch wire loom, which we sell by the foot as part # 459075-1. I'd also use some 1/2 inch loom clamps, part # A0500 to secure the wire loom and hold it where it's supposed to be.

  • Does Titan Brake Line Tee Secure Trailer Brake Lines
    Indirectly yes, the part # T0778500 does get used with brake hoses. If you check out the attached picture you'll see that holds a union tee that hoses run to. We do have clamps that were designed to secure brake lines like with the part # A0500 for 1/2 inch and # A0250 for 1/4 inch. We also have clips, # T0936600, for more brake line support.

  • Parts Needed to Install Tekonsha Brake Controller in 2004 Jeep Grand Cherokee with Factory 7-Way
    To install the Tekonsha Primus IQ Brake Controller # TK90160 in your 2004 Jeep Grand Cherokee you will want to use the pigtail wiring harness that comes with the brake controller. This pigtail will need to be hardwired into your vehicle. The white wire on the pigtail will be grounded at the negative battery terminal, the black wire will need to be ran through a circuit connector and to the positive battery terminal, the red wire will need to be spliced into the stoplight wire at the back...

  • Where to Place the Four Loom Clamps to Support Brake Lines in Kit HBA16-252-82
    In short; they're not secured to the trailer frame. Presumably you would strategically place the loom clamps near those fittings you mentioned from kit # HBA16-252-82 to limit any movement of those fittings. The rigidness of the metal lines will help keep those metal lines in place so the clamps would not be needed for the metal lines. We do have other loom clamps if you want more, # A0500 for 1/2 inch and # A0250 for 1/4 inch. We also have clips, # T0936600, for more brake line support. I...

  • Is it Difficult to Install 7-Way and Brake Controller on 2005 Honda Pilot
    To install a 7-way on your 2005 Honda Pilot, you will need the Universal Installation Kit for Trailer Brake Controller, # ETBC7. This kit includes everything needed to install a brake controller besides the controller itself. For that I recommend going with the Tekonsha Prodigy P2 Trailer Brake Controller, # 90885, because it is highly rated by our customers and is a proven performer. The P2 is easy to set up and includes features like built-in diagnostics, auto-leveling and the flexibility...

I've also attached an article on wiring to assist with diagrams. If you have the electric reverse lockout on your trailer coupler, you may want the...

  • How Is the T-Fitting for Trailer Brake Lines Mounted Without Integrated Bracket?
    There are a couple of ways to mount the Kodiak Tee Fitting for Hydraulic Brake Hose - Brass - 3/16" Female Inverted Flares # BH-T-3FIF. Many will use brake line mounting hardware on either side of the brake line which will provide enough stability like you see in the # 20TA-BLKIT pictured. Others want more of a direct mount like you are seeking use the metal loom clamp # A0500 directly on the T-fitting itself to give you that solid mount and then add extra clamps further down the brake...

  • Replacing Trailer Wiring on a 2000 Jayco 17 Hybrid
    It sounds like the best solution for you is to bypass the existing trailer wiring since you cannot locate the wiring that leads to the tail lights. You can use wiring # 16-4B-1. It is sold in increments of 1 foot. So if you needed 20 feet you would enter 20 in the quantity box. Or you could replace the connector as well. If you have a 4-Way you could use # A35W42B which has 2 running light wires, one for each side of the trailer. If you do not have a 4-Way you could tell me the connector...

    Rewiring your 14 foot dump trailer is pretty straight forward. I would start with a 20 ft.

We have a video detailing how to install this type of harness for you to review, see link. Next, I would use the RV-Style Trailer Connector, # PK12706, and remove the 4-Way connector from the 4-Way harness and install the wires in the proper locations in the 7-Way connector. Our wiring...

    I did some research and found that your boat is 18-ft 9-inches long. You did not say if your trailer has brakes included which will make a difference when installing the wiring. If you do not have brakes on the trailer and you only need wiring for the lights I recommend part # A35W42B. This is a 35-ft long harness and it has a 4-way flat trailer connector included. This is a wishbone harness that means the running light is split at the connector and the brown running light wire is run...
