Video Transcript for The Low-Down on the Cam-Action Lockable Door Latch for Large Enclosed Trailers

Today we're gonna take a look at the three point Cam-Action lockable door latch kit for large enclosed trailers, and a zinc plated steel construction.Now, these are Cam-Action door latch, which is ideal for heavy duty side or rear doors on large trailers. They use the three anti-rack keepers right here with the long lugs that wrap tightly around the pipe to help prevent latch doors from jumping and shifting. This center keeper right here provides additional grip on the pipe itself.On the pipe retainers right here, you'll notice the bolt holes on these pipe retainers are on one side only so that you can mount the pipe here closer to the edge of the door.Now, the handle on this, it is a double action handle assembly. Ensures simple, secure latching. Helps protect against in transit jarring. What you basically do is flip this handle keeper that's on the half, the latch up, and then you just lift the handle to release it, and then rotate the handle to either to release or engage the cam.Also on the handle, if you notice it has a nice black vinyl grip on it.

Makes it very comfortable to use. The hasp itself, you can see right here, it's a bridge type hasp. Helps prevent accidental opening, ensures safe latching action, and if you notice, they have holes that'll line up here so it can be locked with a padlock for extra security. Now, padlocks we do sell separately on our website.All these parts are nice zinc plated steel construction, provide durability and corrosion resistance. Includes everything laid out here on the table.

We mentioned the three anti-rack keepers with the three anti-rack lugs, the two spacers right here, the three top pipe retainers. This is the top portion, and then three bottom pipe retainers. The handle assembly, and then the bridge type hasp right here. It's all included.Now, these are a simple bolt on installation. Now, it will require a three quarter inch diameter standard pipe and mounting hardware, which is not included, to install all these parts.

Handle length on it is about 14 inches.But that should do it for the review on the three point Cam-Action lockable door latch kit for large enclosed trailers and a zinc plated steel construction.

My 2013 Mission snowmobile trailer needed some “TLC”
It was showing its age. Last year I bought the bottom hinges from Etrailer. This year I replaced the door latches.
Absolutely a perfect fit! Easy install, videos are great with helpful tips…very happy to spruce up the sled trailer.
by:

Thanks for the follow up. We just bought a Look 6' x 12' cargo trailer that only had the in-door lock on the side door. Of course we wanted to beef that up and in searching found your site. After reading the reviews we ordered the #305736 36" side door bar lock assembly on 1/20 and received it 1/22. Great! We installed it the next day in about an hour. It went on with minimal effort (drilling the holes was the worst) and looks as if it came on the trailer. We did install the hinge side over the door trim and used backer plywood inside with oversized washers and locking washers. We did the same for the door bracket. The pictures on your site from customers helped us, so we have attached a couple of our own. Thanks e-trailer! The Wheelers

This product still works great and looks like new! We will go to you first if we have any other needs.

I purchased two of the Universal Cam-Door Lock for Enclosed Trailers - 38320. I used them to close barn doors that are 80" by 80" each. The cam -Door Lock works great for these doors. All the parts are very heavy duty. The Cam-Door Locks closes the doors very firmly against the frame from top to bottom, keeping the doors even and level. I have also used this kit to close doors on a wood drying kiln where the doors have to tightly seal. Again, they work great to apply the needed amount of closing pressure to engage the weather seals. This kit is a good buy where you need to close doors with firm pressure.

The Cam Door Lock works great. I am still very pleased with the product. I have recommended it to a number of people.

by:
I had to cut and re weld the hinges to fit the right side of the trailer but it saved me from having to build the whole thing. I am satisfied with the results
by:
I just attached the 36" latch bar. it only took about 30 minutes. Took longer to make sure it was positioned right and not to impede on the rv latch. I included a small bracket on the door as well. Latch hardware seems better the originals on back. 5/16" carriage bolts are needed. I used 2 1/2" then cut off anything past the nut. Pictures included.

Michael,Im doing exactly what you did putting this bar lock over an RV style door. The door is about 12 from being flush with the trailer side and it looks like yours may be too. Did you bend the strap to get it to lay flat against the door? I thought of spacing out the hinge plates so theyre flush with the door but dont think that would look good.Also, did you remove the rear lip on the aluminum trim the hinge plates are mounted over, space under the hinge plates, or just mount over it?Thanks,Steve

Steve,there is an aluminum trim around the rv door, I just bumped the hinge of the bar to the closest lip of that alum. trim to the door basically mounting over the top of the trim -so on top of the left side bump and bumped the right side if that makes sense. it kinda naturally fits. the bar lays nice and tight to the door by just mounting it ad is. Add some metal straps on iside of door mount to beef that up. I used 2 or 2.5 inch bolts with oversized washers on inside alum. jamb and cut off excess bolt and grindedsanded smooth to nut. I siliconed the gaps on the outside above hinge because it wont sit flat due to the alum. trim so water doeant get on by bolts. Hope that helps.

Is there a weak point created when bolting the hinges so close to the edge of the door opening? Could you install one of these by moving the whole assembly to the left, thus creating room for hinge backplates? I guess you would have to lower the mount point as well, to avoid the doors backplate from hitting the factory lock and use a shorter but wider door backplate.I assume you feel your hinges are secure. I have yet to take ownership of my trailer so I dont know what kind of stud is framing the door.I am so happy this accessory is available. I really didnt notice the pitiful side door lock until after I purchased my trailer. A crowbar and about 5 seconds is all it would take to get inside!

Usually these latches are not positioned so closely to the edge of the door. Most of the time, the hinges of the handle side and the latch for the handle are set equidistant from the edges of their respective doors.
by:
E-trailer did an excellent job of shipping and handling of the product sent to me. It is of high quality and should last for years. It was delivered when they said it would be and I have installed it. Quite happy with it but wish that they would stock a 45" bar lock

The latch assembly is exactly what I needed for the shed that I built to house my small refrigerator. The critters or other unwanted cant get in.

by:
You never shipped the hasps nor ANY mounting hardware! I don’t have time for this crap and i am not happy at all!! All I got were handles. Without hasps or hardware, they just sit in the box. Try slowing down to make sure everything your customers order is actually IN the order!!
by:
This item is as advertised!
Just know it is no an exact replacement for the Imperial Stamping hinge used on my Haulmark trailer. This hinge is about 3/16” shorter than the Imperial, so the holes to not match up exactly. So “some assembly required “ - just know that going in. Also the Haulmark doors have about a 3/16” - 1/4” offset or lip on their doors, and the Imperial hinger is bent for this offset, so to close the hinge takes some effort. Like I said, this one will work, just be ready for a few differences.
by:
Fit perfect. Direct replacement...

just what we needed and fast shipping

Great product, just wished it came with instructions. No instructions where ever received, noting on the original manufactures website. So you guess, tack weld, fit into place, and check operation. Took more time than needed due to lack of instructions.

other than the instructions, This product is extreme heavy duty, and will last a lifetime of a trailer. The galvanizing is thick so corrosion is not something that will be an issue during its lifetime.

For my application I preloaded the welded assemblies with a door seal. Where the compression was 1/2 total thickness around the whole door. Works great and due to the length of Turning Arm it is a breeze for even the weakest person.

Another option I would like with this product is an Un-Coated version so it could be painted easier. With my application, I painted over the Galvanizing with the knowledge that the paint will chip off. But hey, a can of Rust-oleum is cheap and application is easy.

Note: these latches only work from the outside of the trailer. If you need to active, deactivate this latch from inside, then this one is not for you application.

My trailer didn't come with one so I was always worried about the side door coming open. Not anymore!! This item is perfect for what I needed, easy install too. A LOT cheaper price then expected! Arrived sooner then was told.

Perfect! No issues....its strong and smooth operation....and PEACE OF MIND my sidedoor will NOT come open driving 65 on the highway.

Item was as described, well made and performs flawlessly. It matched the rear door latches and adds confidence that items being transported or stored in the trailer will remain secured. As others have stated use 5/16 carriage bolts. I found for my use 2-1/2" bolts were way too long. Therefore, I cut them flush and siliconed over them just for good measure. I used 5/16, 2" fender washers with nylon lock nuts. In addition, I reenforced the back walls and door with steel slotted flat bar. I drilled one hole over size to ensure fit between the mounting bolts. I highly recommend this product from etrailer. Always fast shipping and unmatched customer service. You can definitely buy with confidence from etrailer. Great company and staff!
by:
Was exactly as the deteoriating one on the trailer . Easy installation!
by:
Great product! Purchased this to make custom rear doors for a Food Truck, and this works exactly as described and like we need it to. This product requires a separate bar, for which we used stainless steel conduit, as well as welding experience to put it all together. I had to have help with the welding and the overall assembly, which I why I'm giving it 4 stars instead of 5 - not something the general jack-of-most-trades can use, but overall I'm very satisfied with this product, and would definitely recommend it if you have the skills or have access to the skills needed to put it on!

here is a pic of the trailer I built, used the products from your place. started with a simple
utility trailer, and build this enclosed trailer.

Ed- awesome build. Im building something very similar. Where did you get the trim for the door so it can seal? Also what about the larger top trim?
