Video Transcript for Review of Master Lock Padlocks - Universal Application Padlock - ML4140KALH

Today we'll be taking a look at the Master Lock brass padlock. Padlock's good for all kinds of things and this one is going to be a nice wide brass body. So it's going to help to resist any corrosion. And we have a hardened steel shackle, so it's going to be pretty resistant to any cutting. It's gonna be great for any kind of cabinets, fences, maybe a trailer. Just about anything that it'll fit.

We'll have a non re-keyable four pin tumbler cylinder. So it's going to provide a pretty good resistance to any lock picking. Comes with two keyed alike keys. So we can open that up and then lock it back down.It measures overall about 3-1/2" tall. The body is about 1-1/2" wide.

The distance from our lock to the inside top edge there is about 2", maybe 2-1/4. I'd say you really only have like 2" of usable space there. And then the width in between what it'll fit is about 7/8 of an inch. The diameter of that shackle is 1/4". And then the width of our lock going the other way is just over 1/2".

Yeah. No, that's actually 1/2" there. Has a pretty good weight to it. Think it'll make a good addition to keep all of your stuff safe with a nice padlock.And that's going to do it for our look at the Master Lock brass padlock.

  • Is There a Way to Lock B and W Companion Hitch to OEM Ram Rail Kit
    The Master Lock Padlock # ML4140KALH has a shackle that is 1/4" so they will work with the B&W Companion # BWRVK3600 in your OEM Ram rail kit. You will need to continue using the saddle pins while you are actually towing, however; the Master Lock padlocks can be used when you are not towing as a theft deterrent.

  • How to Lock the B&W Companion to OEM Puck System on a 2020 Ram 3500
    It isn't a bad idea to add some security to your B&W Companion OEM 5th Wheel Hitch # BWRVK3600 while it's installed on your 2020 Ram 3500. You can actually use a lock in place of the pins that are used for securing the legs. The lock just has to have a 1/4" diameter shackle like the Master Lock # ML4140KALH.

  • Padlock to Deter Theft of B&W Companion Hitch for Puck System
    I spoke with my contact at B&W who said that any of their Companion 5th wheel hitches for puck systems can be locked with a padlock that has a 1/4" diameter shackle that has at least 2" of usable space. For that we have the Master Lock Padlock. This comes in a quantity of 1 with part # ML4140KALH.

  • Does B&W Companion 5th Wheel Sliding Hitch for Ford Require Adapter Plates for Different Trailers?
    The B&W Companion OEM 5th Wheel Trailer Hitch w Slider for Ford Towing Prep Package - Dual Jaw - 20K # BWRVK3370 does not need an adapter plate for different trailers. Your Keystone Avalanche 5th wheel trailer will work just fine. The 1 inch thick dual jaws will provide excellent connection to your king pin for less undesired movement. You may want to secure the unit to your truck using a pad lock like # ML4140KALH which is a great fit for the latching handles.

  • How to Lock B&W 25K fifth Wheel Hitch using GM Puck System for 2021 Chevy Silverado 3500
    You can use a pad lock ran through the levers of the hitch instead of the snapper pin to lock the lever in the locked position. The lock that will work is the Master Lock Padlock # ML4140KALH for a single lock. You'd only need to lock one of the feet to effectively lock the rack to the rail kit.

  • Will Gen-Y Auto Latch Gooseneck Coupler Lock Work With Reese 18k Goosebox?
    I have a solution for you, but the Gen-Y Auto Latch Gooseneck Coupler Lock - 25,000 lbs # 325-GH-7111 does not look to be a fit for the Reese Goosebox 18k. The Gen-Y Lock requires a lip, which the Reese does not have. I recommend using Master Lock Brass Padlock - 1-1/2" Wide # ML4140KALH to lock your coupler; see attached photo.

  • Recommended Lock for Use with Master Lock 10-mm Braided Steel Cable
    I recommend using the Master Lock Mini Me U-Lock # 8118DPF to secure the 10-mm Braided Steel Cable # 72DPF. This lock is ideal for use with loop-end cables such as the # 72DPF. This lock is made from a hardened steel body that resists cutting, prying, and sawing. I have attached an installation video of this lock for you. Another option is a padlock with a larger opening to accommodate the cables, like the Master Lock Padlock # ML4140KALH. I have attached a review video of this lock for...

  • Availability of Locking 5th Wheel Pin Kit that is Keyed Alike
    I do have a solution for you, but unfortunately we do not have any kits available for locking up your 5th wheel setup. Instead what you can use is the Tow Ready Base Rail Lock # TR63254, along with the 5th Wheel Coupler Lock # e98896, and the Master Lock Padlock # ML4140KALH. These don't have the ability to be keyed alike, but they will provide you with locks to the points that you mentioned.

  • Locking Pins for B&W Companion Puck Latches And Coupler Pins
    For your Companion 5th wheel hitch # BWRVK3305 with a 3/8 inch hole, I recommend the Master Lock Python Adjustable Cable Lock - 6' Cable # 8419DPF. The cable lock can be run through the same locations on both sides and attaches to itself. A padlock is another option you have with the Master Lock Padlock # ML4140KALH. Included are video resources for both solutions.

  • Lock for the Curt Q25 5th Wheel Hitch for Chevy/GMC Towing Prep Package C16069
    The recommended lock to secure the Curt Q25 # C16069 is the # ML4140KALH. This is steel and brass lock with a 1/4 inch shackle diameter that you would use in place of one of the pins that secure the handles in place while the hitch is installed. Another possible option is to use a cable lock such as # e98891. Weave it through the hitch and a tie down point in the truck bed.

  • Will My Older B&W Companion Head Fit the BWRVB3305 Base
    Yes, the B&W Companion line of 5th Wheel Hitches all use the same head, which is part # BWRVC3006. So, if that is what you have then it will fit the Replacement Base for B&W Companion OEM 5th Wheel Trailer Hitch # BWRVB3305. I also confirmed that the Replacement Base # BWRVB3305 is confirmed to fit your 2017 Ford F-350 Super Duty (8 Foot Bed) with OEM Prep Package. For extra security, I recommend replacing the cam-action handle pin with a padlock like # ML4140KALH. I have included a...

  • Locking Key Safe for Ram Truck Key and Locks for Curt Q25 5th Wheel Hitch
    The Master Lock mini key safe, part # 5408D, is pretty small and the part the lock connects to in the safe blocks a decent size key from getting in. I'm not exactly sure what your 2016 Ram 3500's key looks like but I'm fairly certain it's a key fob like in the picture I attached. If so it won't fit in the safe. Instead take a look at the Master Lock Safe Space storage box, part # ML5900D. It's quite a bit larger so pretty uch any car key should fit and it still uses a combination to...

They have the same lockable handle, specifically designed so that you can add a padlock to help prevent theft and give you that peace of mind you're looking for. The Master Lock Padlock # ML4140KALH is the one I recommend for your Mopar Hitch.

  • How to Lock Convert-A-Ball CAB-C5G Cushioned 5th-Wheel-to-Gooseneck Adapter
    The # CAB-C5G Convert-A-Ball Cushioned 5th-Wheel-to-Gooseneck Adapter can easily be locked by using a padlock like part # ML4140KALH. . You'd pass the shackle of the lock through the locking handle slot and out the hole in the foot of the coupler. This prevents the coupler from being opened, so it can be used while the trailer is hitched or when it's not. Either way, the lock will help deter theft by making it difficult to unlock the coupler.

  • Hitch Mounted Cargo Carrier for a 2017 GMC Yukon
    I recommend the CarPod, part # M2205-01-02. This larger, folding carrier will work with your vehicle's larger hitch. The CarPod is a walled, lockable carrier that includes a weather-resistant bag. This carrier can be used with or without the bag for a wide range of applications, and can be easily locked with a 1/4 inch diameter padlock like part # ML4140KALH. The rack also can have its lid removed and when folding up, can be folded completely flat for improved clearance. The CarPod has...

  • Solutions for Locking Truck Bed Camper When Not on Truck
    There isn't a specific product available that is designed to secure your truck bed camper when it's not on the truck, but I do have a few solutions that will work well. I first recommend looking into some standard cable locks like our # e98891. You can run a few of these through the tie-down loops on the camper and secure them to some anchor points. You might also use some chain and padlocks like the Master Lock # ML4140KALH. One other item you might be interested in to set your mind...

    The Blaylock # BLTL-60-40D isn't available with keyed alike locks, but you can purchase just the assembly that installs into the lunette ring, part # BLTL-60 by itself and purchase keyed alike locks separately. The Master Lock # ML4140KALH would be a good choice for a keyed alike lock. Simply choose the 'keyed alike' option from the drop down menu on the linked product page.

It will be a stronger option with less limitations due to that.

  • Will Carpod Cargo Carrier be Able to Transport 150 lbs Yamaha Inverter Generator?
    The Carpod Cargo Carrier # M2205-01-02 has a weight capacity of 450 lbs, is 48-3/4" long x 24" wide x 22" tall, and the weather-resistant bag that comes with is 46" long x 22" wide x 22" tall. The Yamaha inverter generator that you referenced is 26.8" long x 17.5" wide x 21.9" tall, so this carrier would work with 1/10" to spare. You would also want a hitch pin and lock, # PC3, or an anti-rattle hitch pin and lock, # 63232 to go with it. For the security you are looking for, your best bed...

    The only way we can recommend you lock the B and W Companion hitch # BWRVK3600 to the factory rail kit of your 2016 Dodge Ram 3500 will be with a pad lock like the # ML4140KALH as there isn't any other way to lock the feet. Most thieves are going to be deterred by the sheer weight of the fifth wheel hitch which will make a quick getaway nearly impossible and also the presence of a padlock. A determined thief with enough time and the correct tools typically can get what they want, but with...

  • Cover and Lock Needed for 2014 Ram 3500 OEM Puck System and Curt Q25 5th Wheel Hitch
    To cover the Curt Q25 # C16049 installed on your 2014 Ram 3500 I recommend the Classic Accessories Cover # CA80116. There isn't a custom cover for the Q25 but this is a great option that has had a lot of success with many 5th wheel hitches including the B&W Companion which is a bit bulkier than your Q25. The cover for the center hole for the OEM puck system on your Ram is part # C66145. It has an inner diameter of 2-1/4" and an outside diameter of 3-1/4" which matches up with what comes...

    For your 2019 Chevy Silverado 2500 with the OEM puck system I recommend going with the B&W Companion 5th wheel line of hitches because of their American-made heavy-duty construction, ease of use, and how satisfied other customers are with this hitch. The Companion comes in a 20K # BWRVK3770 sliding version if you have the 6-1/2' bed but if you have the 8' bed then there is both a 20K # BWRVK3700 and a 25K # BWRVK3705 option.
