The closest thing to factory trailer door hinges on the Internet and by far the best price. If you are looking for bolt on hinges that can open all the way and fold flat, stop searching and buy these. They are also the best price. They shipped fast and arrived in time to get my scramble horse to a show. With my new trailer doors we are going to have no problems now !

So far the part had been great! Ive recommended the hinges to anyone that has admired the doors. The tension has stayed tight which is great so the doors dont swing around in the breeze.Have a great day!

Just the hinge I wanted. Could not find locally. Wanted 270 degree swing. I can latch the door open at 270 degrees with latch 383400 and it does not swing around. Holes are a bit odd to me. 3/8 for hinge base plate and 5/16 for door strap. I drilled 5/16 to 3/8 to use identical torx hardware in all holes.

For the curious, this box was designed to hold 2-3x what a normal truck does, and collapse flat in garage when not needed. I could not find such a pre-designed product, so I made one.


Product works great for my barn door install on my DIY toy hauler ..arrived earlier than expected with no hassles.


Awesome ..just the hinges i needed for my rwar barn door toy hauler project

etrailer the best place to go to get anything trailer-wise!!.....My recent purchase of two trailer ramp door heavy duty hinges were available, and the very same I purchased some years ago from them....Not too often do you run into an online company such as this that has a tremendous stock, ready to go out on order, arriving in just a matter of days.......Crystal is a pleasure to deal with, a very knowledgeable and pleasant Lady!!..


Hinges worked absolutely perfectly. Used for the rear door of a mini-horse trailer my Son and I built my Wife. Has been used for a year and still look brand new.


I purchased 2 hinges and one hasp door lock. I was custom building a tool trailer and was able to modify them to work properly with my design. I am now on the second version of the same trailer and the equipment is in the plans to use again but in a different location. They are very versitile.

The hinges and door latch are working fine on the trailer I built. I have remodeled it a second time last year and I am still using your hardware. The quality is very high in respects to me doing it at home and not in a professional fabrication shop. Should I ever need anything further I will be contacting your company for material.

Heavy duty hinge! Excellent quality that replaced perfectly 15 year old enclosed utility trailer rear 270 degree swing door strap hinge that would no longer swing back properly. Very happy to have my trailer door open and swing back all the way smoothly thanks to this new strap.


It was exactly as described. I replaced aluminum hinges from the manufacturer, which twisted and bent the fist time I opened the trailer gate. These steel hinges I have opened and closed fifty times plus with no problems. Always a pleasure to deal with etrailer.


Shipment arrived as promised. On time, in perfect condition and complete. I used the parts to convert a "Drop Down" door on my trailer to "Barn Doors". Parts are heavy duty and should last for the life of the trailer. I would have no concerns about ordering from in the future.


We actually did not use this for a hinge... but a custom application in our cargo trailer conversion. Worked perfect for what we were working toward accomplishing. I appreciate your folks there working with us to get what we needed!!!!


Thank you for the follow up email , you are the first company to want the a follow up a year later . Like car dealers want to know how you like the product the next week or so after you buy it ,they could care less what you think a year later. I believe the hinges are great I sold the trailer they were used on but I will follow up on this . great idea !


Great hinges. Replaced my original rusty polar hinges on my trailer here in Hawaii myself with no problems. Service was great and shipping was much faster than I expected. Would absolutely do business with etrailer again.


Perfect for my home made trailer enclosure. Allows the door to swing completely open, just wha I was looking for. I had shopped several local outlets for the right hinge without succes.


the parts came fast at a great price, is now my favorite place to buy trailer parts!




Part was what I was looking for. Fast shipping helped me a lot.


I was shocked to find such heavy good quality hinges at such a reasonable price.
We had to replace hinges on a very heavy door, and these had the heft I had been looking for.



EDDIE S - 10/15/2017


Nice heavy duty looks well made thanks


I had this item a year now and it is working as good as the day I got it no rust great item I will shop here in the future.


I was surprised to see this excellent quolity of product. Very well engeneered and build. Easy to install. Swings 270* and then more.


Customer service is great and the product is as well. Very happy with my purchase.


Great. Very.


Great hinge worked real well for my doors


Good hinge

  • Hole Distance Dimensions of Cargo Trailer Strap Hinge Part # 2212
    I was not clear on the actual dimensions you were needing, so I have provided a photo showing the hole dimensions. The distance from the hinge pin itself to the first hole on the strap is exactly 3 inches to the center of the hole. The distance between the two holes on the portion of the hinge that would install on the door jamb is 3-1/4 inches, center-to-center. These holes are 3/4 of an inch away from the hinge pin.

  • Load Capacity of Polar Strap Hinge for Enclosed Cargo Trailer Doors 2212
    There is no specific weight capacity listed for the Polar Strap Hinge for Enclosed Cargo Trailer Doors # 2212. I confirmed this with Polar. When replacing an existing hinge on an enclosed trailer you will want to match the general size and number of hinges originally on the door. This item uses heavy 8-gauge steel material and so it will be up to the task of supporting a trailer door so long as it is roughly the same size as the original. If your door had three hinges of this approximate...

  • Does the Strap Hinge for Enclosed Cargo Trailer Doors Come With Hardware Or Is It Offered Separately

  • Recommended Strap Hinges For 4 x 8 Foot Doors for Enclosed Trailer
    What you're planning sounds like it would work, but you'll need to be sure you have some cross members in the door where each hinge mounts. Since the doors are large and are likely pretty heavy, I'd use the biggest hinges you can. If you were wanting the hinge to swing all the way up against the side of the trailer, I'd recommend using # 2212. A hook and keeper, part # 383400 would hold the door open for you as you load/unload. If you only need the door to swing 180 degrees, use # 2512....

  • Door Hinge for 2001 Exiss Horse Trailer
    The hinge you referenced part # PLR2212-AS would replace what you have now on your horse trailer and the holes would line up. It looks like for your window you'd need a piano hinge that's about 2 feet long, but at this time we do not have any in that length.

    While we do have a hinge that is going to let you have a gate that swings to the inside of the trailer and to the outside for a 270 degree swing, the hinges you referred to would not allow that type of movement. Instead, you will need what is called a square corner hinge, and you have a couple of different options based on the length and metal construction you want. The following options are below and I have added links to video reviews for you as well. - Square Corner Hinge with Reverse...

  • Determining the Correct Camper Tie-Downs for a 2018 GMC Sierra 1500
    For your 2018 GMC Sierra 1500, you can use either the TorkLift Custom Frame-Mounted Camper Tie-Downs # TLC3214 or the TorkLift Custom Frame-Mounted Camper Tie-Downs # TLR3500 for the rear. The front is a bit more tricky. The TorkLift Custom Frame-Mounted Camper Tie-Downs # TLC2212 (C2212) do fit the 2018 GMC Sierra 1500, but only if you have the 8' bed, no board or step underneath the truck bed and have a factory or non-Torklift hitch.

A better option for that application is the T-Strap Hinge for Rear Trailer Doors - 12-3/8" Long - Steel # PLR4040, the Square Corner Hinge with Reverse Bracket - Polished Stainless Steel - 12" # PLR2212-SSP, or the Over the Seal Hinge - Narrow Bracket - Aluminum - 12" #...

  • Cam Style Trailer Door Latch Recommendation For Limited Clearance Area for Brackets
    The big difference between the Cam Door Latch # PLR458-018 and the # PLR658-002 is the robustness of the pipe mount on the handle side. The # PLR658-002 is more for heavy duty applications and comes with bushings for the pipe to mount in. This requires a 1-5/16 inch diameter pipe and the other requires 3/4 inch diameter. That said, since you said you only have a space of 2-7/16 inches for the bottom bracket to fit you'd actually want the part # PLR258-002 instead as it has a smaller sized...
