Video Transcript for Review of Buyers Products Self Adhesive Magnetic Mounting Plate - 3378895404

Hi, everybody. Andy here with etrailer.com. And today, we're gonna take a look at these Buyers Products self-adhesive, magnetic mounting plates. Now, these plates are going to stick to your cab roof to enable you to use magnetic mounts on your aluminum cab truck. And these are going to be ideal for a magnetic light mounts such as your light bars, strobe beacons and spotlights. But they're also going to be great for many magnetic mount CB and ham radio antennas with a wider base.

So, that'll have a better connection to the plate itself. And the strong and durable 3M tape is going to stay stuck to your truck, even at highway speeds and even through demanding weather. You just wanna make sure that you stick the strips to a flat surface. And you also wanna make sure that you completely clean that surface before sticking these on. Now, these magnetic plates are made with a black powder coated carbon steel, making them durable and resistant to corrosion.

I pulled out my little magnet here just to show that they are indeed ready for your magnetic bases and mounts. And let me pull out my ruler here just to go over some measurements here with you. These are going to be measuring 3 1/2 inches by 3 1/2 inches. And you are going to get four mounting pads. Instructions are included to go in a little more detail about actually mounting these on your vehicle.

And that's gonna conclude our brief look today. I do hope that it was helpful for you. Again, my name is Andy. Thank you for joining me..

I have them mounted on top of my 2017 F-350 for a year now and have had no problems so far. My magnetic mount CB & Ham Radio antennas have hit low hanging tree branches and have not had any problems at all. Great product. Would buy again.




by:

They look like they should work... are those small strips of double sided sticky tape all that holds them to the truck? They hold at freeway speeds?


Comments
Yes, thee adhesive backing is a strong 3M tape that will hold to the truck. They can withstand freeway speeds.

  • Do Buyers Products Magnetic Mounting Plates Damage Paint on Vehicle and Can I Go Through A Car Wash
    The Buyers Products magnetic mounting plates part # 3378895404 are backed with 3M tape which is designed to not affect your paint. I do recommend when you go to remove the magnetic plates to use Goo Gone or 3M General Purpose Adhesive remover to dissolve the sticky residue before trying to remove the plates. Going through car washes may rip them off if you go through one the first couple of days after installation but will be fine after that. I do recommend to remove the light bar from...

  • Magnet Mount For Wilson 5000 CB Antenna On Aluminum Body Truck
    I have no doubt that the Buyers Products Magnetic Mounting Plate part # 3378895404 will stay attached to the aluminum body of the 2017 F-350 at highway speeds, however the plates are designed to be used for magnetic lights which have a much lower profile than your Larsen 150 Ham Radio antenna which is very tall with a narrow base. At highway speeds the Larsen antenna will most likely not be able to withstand the wind pressure. I took a look at your Wilson 5000 CB Antenna and the base is...

    Yes. The Buyers Products Magnetic Mounting Plate - Self-Adhesive - 3-1/2" Square - Qty 4 # 3378895404 are designed for use on aluminum cab trucks but can also be used on aluminum sided trailer. This will work very well for your magnetic sign.

  • Can the Buyers Products Magnetic Mounting Plate Be Used From the Inside with a Fiberglass Roof
    I contacted the manufacturer about if the Buyers Products Magnetic Mounting Plate # 3378895404 will work through the fiberglass roof on your 2000 Jeep TJ, they were able to inform me that the fiberglass will weaken the magnet too much to be safe for use through the roof from the inside. You will still be able to use the magnets but they will need to be used on the outside of the roof. The magnets are attached using 3M tape, so they are not a permanent attachment and can be removed if you...

  • Dimensions of Buyers Products Magnetic Mounting Plates and Will They Fly Off In Wind
    The Buyers Products Magnetic Mounting Plates # 3378895404 that you referenced measure exactly 3-1/2" x 3-1/2". These feature strong 3M tape strips on the backside that securely attach to the aluminum body on your vehicle. The magnetic top would then be used to mount magnetic lights like the Blazer # C4850AW you were looking at. This will provide a really secure connection that will not fly off in the wind during travel. Both the self-adhesive squares and the magnetic light are designed...

  • How to Attach Magnetic Emergency Light to Aluminum Body Truck
    I have a perfect solution for you!

  • Are Buyers Products Magnetic Mounting Plates Easy To Remove and Do They Damage Paint on Vehicle
    Since your truck body is aluminum in order to install the Magnetic Blazer Amber lights part # C4850AW you need the Buyers Products magnetic mounting plates part # 3378895404. The steel plates part # 3378895404 are backed with 3M tape which from my research does not affect your paint if you use Goo Gone or 3M General Purpose Adhesive remover to dissolve the sticky residue before trying to remove it. They are one time application so once you have removed them you need more double sided tape...

  • Does The 3M Tape On Buyers Products Magnetic Mounting Plate Damage Car Paint?
    The Buyers Products Magnetic Mounting Plate - Self-Adhesive - 3-1/2" Square # 3378895404 uses 3M adhesive tape which is used quite often in the automotive industry and it will not hurt the paint on your roof. Just make sure that you clean the surface prior to installation, and also use some sort of adhesive remover such as Goo-Gone when removing the plates after your vehicles no longer need them. These plates are designed to be used with various magnetic-mounted lights such as Blazer Amber...

  • Tail Lights Covered By Bike Rack Solution
    The lights on the Demco Tow Lights w/ Wiring Harness # DMKKLB do not adjust from the vertical 180° position. The feet on # DMKKLB do adjust positions left and right for different angles. I recommend using the Magnetic LED Tow Light Kit # TLL21RK to alleviate your blocked tail lights. The harness plugs into your 4 way flat trailer harness and uses magnetism to secure to the back of your vehicle. If you have nothing for the magnets to stick too, you can use # 3378895404 to fix that. Please...

  • Best Bracket and Light To Add To Hollywood Bike Rack
    I recommend to use the 6-1/2" oval bracket part # BK70BB with the lights of the LED light kit part # 98174LED because the 6" oval will be a tight fit. They will fit perfectly into the 6-1/2" oval bracket with the grommets on the light. I have attached a photo for your reference. The brackets will require self tapping screws or zip ties to hold them on. Another option is to use the Magnetic LED lights part # TLL21RK on the vehicle itself instead of trying to attach them to the bike rack....

  • Solution for Blocked Tail Lights When Using Thule EasyFold XT Bike Rack
    I do have a solution for you, but Thule doesn't offer a light kit specifically designed for your EasyFold XT bike rack, # TH903202. One option is to use the LED Light Kit # 98174LED along with two mounting brackets # BK70BB . This would most likely require permanent modifications to your EasyFold though, since you'd need to drill holes to mount the lights on the rack itself. You could try to use zip ties to attach the mounting brackets to your bike rack, but it wouldn't be the most secure. A...

  • How To Add Taillights to the Thule EasyFold Bike Rack
    There a few options to add tail lights to the Thule EasyFold XT 2 E-Bike Platform Rack part # TH903202. You could use the brackets part # BK70BB and LED light kit part # 98174LED which is designed to add lights to cargo carriers. Since the rack is plastic the only way to really allow these to mount is to use zip ties. This would be the only semi permanent solution to adding the brackets to the bottom of the bike rack. The easiest and less invasive way to add lights is to simply use the...
