Video Transcript for T-Strap Hinge for Enclosed Trailers Review

Today we're going to be taking a look at the Polar Hardware T-strap hinge for side and rear trailer doors. Now this strap hinge lets your side or rear trailer door swing open 180 degrees. You can see how easily the hinge on the unit operates. It's going to allow for easy opening and closing. Now this is a long strap that provides more contact area with the door to excellent support. It's going to feature a non-removable pin for extra security.

That pin diameter is about a half inch. It's a nice heavy-duty design, very strong and durable. It's going to be a zinc-plated steel construction that provides durability and corrosion resistance. A few measurements to go over with you real quick, starting with the overall length. Measuring from the back of the hinge to the end of the strap, it's about 17 and 5/8 of an inch. When it comes to the dimensions of just the hinge, that's going to give us a length measurement of about 4 and 1/2 inches.

Going this direction from the end of the hinge to about the center of the pin, maybe a little bit forward, is about 1 and 5/8 of an inch. The mount holes on the hinge are separated on center by 3 and 1/4 inches. Then the strap length, take a measurement of that as well. It's going to be about 16 inches long. The width of the strap, it's going to be about 2 inches wide. You'll notice that there's three mount holes on that strap.

You can see those there. If we take a measurement, the distance that we have between each hole, center on center, so from this one to this one, is 6 and 7/16 of an inch. From the center one to the furthest out one is also 6 and 7/16 of an inch. Now these holes on the strap will accept 5/16 inch-diameter hardware. The holes on the hinge will accept 3/8 inch-diameter hardware. That's going to do it for today's look at the Polar Hardware T-strap hinge..

I think the product is great. I think Emily sucks as a customer service agent. Ignored my voicemail and email.

Was supposed to be here a week ago and I needed some assistance and had to contact someone else because I got no response from this person.

I am giving 5 stars because when I called and spoke with John, he was very helpful and understanding of the issue that I was having. He helped me place my order via phone and ensured that my item was shipped out same day so I could have it next day. It has been 24 hours, and I was just notified that my parts were delivered. Don't get me wrong, I paid for it, but it actually happened in a world where no one actually wants to make sure things are done correctly. Thank you John for your help.

The hinges are very heavy duty, I searched for months for the perfect hinges to support my barn doors. The hinges are the perfect addition to provide the support required for the doors. Upon opening the doors, there is no sag, the hinges are very smooth during operation. This is a great product and I wouldn't hesitate to purchase more. Karen is awesome to work with, she went out of her way to make sure the product shipped in a timely manner and the order was filled properly.

I’ve used these for metal doors before. They are stout and tight initially, but once installed they swing easily without any wobble. They have been like that for the last three years with frequent use. If they’re installed solidly and oiled occasionally they should last a very long time.

A year later and the latest hinges work perfectly. No surprise. A simple thing, but manufacturing quality creates a reputation.

I saw a ramp door online and copied it for my shed. I built the ramp door from the shed double opening doors and used most of the parts from etrailer.com. Hinges are sized for the weight of the ramp door and work great.

  • In Need Of A T Strap Hinge, 18", For My Food Truck
    Hey Keith, The closest hinge we have to that is a 16" with 3 holes in the hinge. Part # PLR3416 is what we have close to that. I am not sure what originally came on the food truck but if you want to send me a photo of what you had on it I can get a better idea of what you are needing and see if we have something. The one we have has 3-1/4" between the holes on the hinge. It may be able to still work with yours without using the middle hole. If you want to email me a photo of yours I...

  • Stainless Steel T-Strap Hinge for Side and Rear Trailer Doors
    Polar T-Strap Hinge for Side and Rear Trailer Doors # PLR3416 is galvanized (zinc-plated) steel but not stainless steel. The zinc coating helps resist corrosion. For a similar hinge that is stainless steel we offer Polar part # PLR3416-SS.

  • Does T-Strap Hinge # PLR3416 Have Weight Capacity
    This T-Strap hinge # PLR3416 does not have a weight capacity stated for it. If you wanted to use it on a 150-200 lb door our best recommendation would be to use at the very least 3 but ideally 4 to distribute the weight like you mentioned.
