Bought two of these to complete my ramp door project for my Sprinter van. They worked great for my purposes and would buy them again if needed!
Quick delivery
Great product, fast shipping, highly re commend
The 36" LockSide Door was shipped fast and was just what I was looking for.
It was the correct size for my door and was easy to install. Took about and hour and fit . All I Had to do was get the hardware to install . Would buy this product again and would recommend.
Amazing service!
Pretty nice product. Appears to be made in the USA by Polar. One of the welds is what I would call sub par, but the rest look OK. Easy install on my cargo trailer's side door. Takes 5/16" carriage bolts.
It arrived faster than expected! Great condition and exactly what I need to secure my car trailer door.
Holds door securely shut. I added a custom bracket to stabilize the side of this homemade box, by using the back door as a shear wall. See special bracket just below top hinge, under rod. The right wall cannot vibrate when driving, or be pushed out by contents inside.
My shed door didn't close well and the shed was becoming a haven for wasps. After searching for a door latch that would seal the door I found your website and you had the perfect product for my project.
Your site was easy to navigate and simple to use. I was happy with the email updates on the shipping status and the latch arrived in good time and in good condition.
This might be the first time your trailer parts were used to fix a shed, so I'm including a picture.
All in all, a great experience.
Cut up my wife’s cutting board to make a spacer for the side door, other than that piece of cake. Much better than the original latch with a padlock.
We recieved our door-bar on Thursday Evening, and Friday I installed it in about an hour. I purchased $7.50 worth of carriage bolts & washers & ny-lock nut. 2.5 carriage bolt for the 36" rod hinge & 2" for the door. Our older Aluma trailer door lock with the "rod & lever" closure was not keeping the door completely closed plus the keys are obsolete and needed a new key.
With this set up my doors stay sealed to keep out dirt & dust and I can use any heavy duty lock. (Lock upgrade purchase soon) Thanks for fast delivery service too. Odered on Monday & recieved on Thursday!
Plus we love our 1.25 receiver hitch for our VW Jettawagen which we use to haul our bicycles! (purchased in October). We Paid $75 to have it professionally installed but saved $100 on the hitch.
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?
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!
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.
just what we needed and fast shipping
Fit perfect. Direct replacement...
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.
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!!
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.
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!
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
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.
Perfect fit, high quality and quick shi pping!
Exact replacement for me. No hardware which they do tell you beforehand. I had 25 dollars in new bolts and nuts etc.
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.
