I used these hinges on my shed doors, two on each door, each door is 4 feet wide by 7 foot tall. The doors are light and strong so as not to max out the weight rating of the hinges. I went with my own experience to determine how much weight the hinges will take. I would of liked to know the weight rating of the hinges, but could not find it. So far they work very well. I will keep lube on the pins because of being out in the weather, and to see how long they will last. They are a well made hinge and depends on your use should last, as long as you don't over load them. 642190

The strap hinges that were purchased from etrailer were lightly sandblasted and painted black to match frame and other hardware on rebuilt trailer. The hinges were the perfect solution for the tailgate which provided the option to support the tailgate in the horizontal position with chain or rotate the tailgate completely down and out of the way. 513282

by:

After a year of use, the hinges I bought are functioning perfectly. Very sturdy. More important is the depth and quality of the service from etrailer.com: 1. Excellent specific part service. The detail in the photos of my specific hinge - WITH dimensions - enabled me to buy EXACTLY what I needed the first time. The staff provided the dimensions - they were not from some standard, 'similar' hinge. 2. Quick delivery. 3. Easy access to real human beings who actually know something about the products. Very rare. 4. etrailer.com is my go-to vendor for all trailer parts. 490467

  • Removing Old Strap Hinges on Cargo Trailer that Use Rivets to Secure
    You are going to have to drill out the old hardware that is holding your hinges to your cargo trailer currently as they are basically rivets. The strap hinge replacements part # 2512 that you referenced will work really well for your setup as replacements. Best option will be to determine the type of wood and dimensions of your current doors and then go with wood that matches that. You could use larger rivets to attach the hinges or use carriage bolts ran through the hinges and secured...

  • Is There a Weight Capacity for the Polar Strap Hinges
    I have reached out to my contact at Polar before asking about the weight rating of their straps, like part # 2512, and I have been told that they don't really have a weight rating. There are so many different variables into the equation that it is next to impossible for them to give an accurate answer. I can say that they have directed me towards the Ramp Door Hinge # PLR1902 for heavier duty applications though. This is a much better application for a ramp as the stap hinges are meant...

  • Availability of Aluminum Corner Hinge for Truck Body that Wont Corrode
    The closest solution we have to what you are looking for is the Polar Aluminum Square Corner Hinge part # PLR2212-AS which will not corrode as it is aluminum but the dimensions are a bit different than what you listed. The dimensions are overall 12 inches in length, strap width is 2 inches, and the mounting holes are separated by 3-1/8 inches. For more info on this hinge plus a few more dimensions check out the review video I attached as well.

  • Replacement Strap Hinge for 1998 Keifer built Golden Eagle Trailer
    From the look of your picture I'm guessing you have the 180 degree Polar strap hinge part # 2512. The entire strap from the hinge is about 12 inches long from the center of the pin and the holes are 3-5/8 inches apart on center. If this doesn't line up exactly can you tell me the exact measurements of your strap's hole spacing?

  • 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 #...

  • Dimensions of Door Strap Hinge # 2510 for International Trailer
    I have provided photos showing the dimensions of the # 2512 hinge, which you can compare to your existing hinge. This should give you a good idea if the # 2512 hinge will work for you, as I do not have any information about the OEM hinges on your International utility trailer.

  • Hardware Recommendation for Installing Polar Strap Hinge for Enclosed Cargo Trailer Doors # 2512
    I went to our warehouse to check the dimensions for the mounting holes on the Polar Strap Hinge for Enclosed Cargo Trailer Doors # 2512. The two holes on the smaller end of the hinge measure 0.4-inches (10mm) and the three holes on the larger end measure 0.34-inches (8.5mm) in diameter. Since this item is galvanized you'll want to use galvanized hardware (or stainless steel) for installation on your trailer. I wish we offered hardware for this but since we do not your best option...

  • Recommended Replacement Hinges For Barn Doors On Dump Truck
    We do offer a hinge that may work well for you. I recommend part # PLR1904-Z. This is a barn door hinge for dump trucks and is made of 1/4 inch steel. This has a smooth surface that is designed for welding. I have also attached a photo of this hinge you can take a look at. I have also attached a photo of the four strap hinges that might work for you. As you can see, these have holes drilled in them so they can be bolted in place for both the door and the trailer.

  • Possible Solution to Fix Sagging Trailer Doors
    You will have to determine where the sag is coming from. Are the hinges worn out? If so, you would need to replace them. We have strap hinges like the part # 2512 which are commonly what is found on barn style trailer doors.

  • Difference Between Strap Hinge 2512 and Over-the-Seal Hinge PLR2512-AS
    In the case of hinge # PLR2512-AS, which is an over the seal hinge, and a strap hinge # 2512, there isn't a difference. A hinge that is designed with that raised section near that actual hinge part can be considered an over the seal hinge because it reaches over a seal or molding. It just so happens that many hinges described as strap hinges have the same design. I have linked videos on both hinges for you.

  • Availability of Cargo Trailer Strap Hinge with Mounting Hole Spacing of 4-1/4-Inches
    I checked the dimensions of all of the strap hinges we offer; all can be seen on the linked page. One of these, Redline part # 2512, did not have the mounting hole spacing noted on the product page so I pulled one from stock so that I could get that information for you. The hole spacing is noted on the linked photo that I have prepared for you. None of these hinges has the exact spacing you're looking for, I'm afraid. If you do end up using an alternate part and have to drill a new hole...
