Video Transcript for Polar Hardware Enclosed Trailer Parts - Doors - PLR1902 Review

Today we're going to be taking a look at the ramp door hinge from Polar 00:00:05 hardware. This hinge is designed for ramps or heavy access doors on your trailers. It's made from a very strong and durable steel construction. It's going to have that plain or raw finish, which allows for easier welding for the installation. You'll notice that right here it does come with a grease fitting. That's going to allow for long life and smooth operation.

Once this is installed all you have to do is attach a grease gun to that, pump in some grease. That's going to lubricate the internal pin and it's just going to allow for really nice, smooth operation. Overall, it's going to increase the life of the hinge. A few measurements to go over with you real quick. The thickness of the plate right here is going to be 1/4-inch steel. Going this direction, that plate is going to measure 4-inches.

Going this direction, it's going to measure 2 1/4-inches. The length edge to edge, we're looking at a measurement of 8 1/4-inches. Then the ends are going to have a diameter of right around 1-inch. Really nice operation though. It's going to rotate all the way.

Very easy to do and again if that ever gets tight or whatever, hook up a grease gun, pump in the grease, it's going to lubricate the internal components. That's going to do it for today's look at the ramp door hinge from Polar hardware.

I received my Ramp Door Hinge and it is heavy duty and was packaged with care. I even called customer service to check arrival time and the individual who helped me was very kind. First of all a person answered the phone, second she did not ask for an order number just my name and she was able to tell me exactly what was going on with my order and when it should arrive. My order arrived exactly when she told me. I am hoping to get it welded on today and if I am able I will try to return here and post pictures. Thank you guys.

My parts were promptly shipped, in good condition upon arrival. Perfect fit for my application, and have had no problems over the last year. Application was for a 2010 piece American car hauler rear door ramp hinges.

Great job. Hinges just what is advertised, heavy duty.

Hinges still work great after a year. Moving a Kubota garden tractor and other equipment over down gate and hinges hold just fine.

Great value on heavy duty hinges. I had a custom Bifold landscape ramp built. And used 8 of these hinges. Four at the body and four at the Bifold. Works great. Shipping was super fast. And packing was excellent. Looking forward to my next purchase with etrailer..

Let every one know from start to finish I was glad o chose you company. One improvement I would recommend is once the tracking number is available, include it in the email. That way it’s another way to track its location. Thanks again for the Great customer service and using UPS.

One is hard to move and the other hinge is stuck. I think they are both bent. Not happy. Waste of time waiting for them


Comments
These are heavy duty and they require you to weld them on then apply a grease gun onto the fitting. Once you pump grease into the internal pin, it will become lubricated and easier to move.

The hinges looked good but they were rusty. It would be nice to get hinges that you could move by hand. 2 of the 4 i had to put in a vice and use penetrating oil to get them to move at all.

We've used these hinges on multiple heavy duty, weld-on applications and they are quality, solid, and extremely durable and strong. The extra thick barrels make welding them onto frames extremely easy.

Good product but the hinge part would not turn. Contacted Sal at your office and he is replacing the 2 hinges. Very pleased with your shipping time.. Very pleased with the promptness of sending us the new hinges. Very pleased with his assistance.

Ordered these to use on a landscaping trailer for a rear ramp gate that will hold at least 800 pounds got 3 of them to spread the weight out, seemed heavy duty and they are, these are big hinges in a good way. The zerk fitting is a great plus! makes it easier than fabricating your own hinges. The square plate makes it easy to align and gives you enough material to weld to.Price was goog shipping was fast, customer service is always excellent.


Comments
One year later they are still working perfectly. They have stood up well, can be greased easily, hold a lot of weight, over 800 pounds at a time have gone up this ramp using 3 of these hinges, no issues.

  • What Could Cause Ramp Door on Enclosed Car Hauler to Become Out of Line

    The Ramp Door Hinge # PLR1902 that you referenced does not come with 2 of the plates for welding. You will weld the plate to one surface and the outside ends of the pin to the other for installation. For a hinge that has 2 of the plates you would want the Polar Butt Hinge # PLR1005.

  • I'm Looking At An Aluminum Butt Hinge For My Horse Trailer Ramp, Is This A Good Hinge?
    An aluminum butt hinge like Polar's # PLR1005 is a durable hinge that could work great on your horse trailer. My only concern with this hinge for your application is if your frame is steel instead of aluminum which could cause galvanic corrosion because they are dissimilar metals. If your frame is aluminum, I think this is a great choice and you will just need to be careful welding. I don't know how many you would need for your application, but most trailers use a minimum of 3 or 4....

  • Will Polar Hinge # PLR2216 Support a Ramp Door?
    The Square Corner Hinge with Reverse Bracket - Zinc Plated Steel - 16" # PLR2216 are not rated for a weight limit. For a ramp door, I recommend instead using the Ramp Door Hinge - Steel # PLR1902 which is a much thicker metal and a stronger pin. This is designed for that function and needs to be welded in place. The Square corner hinge although easier to install would risk hardware failing as they aren't designed to hold weight beyond the door itself.

  • Replacement Ramp Hinges for Enclosed Trailer
    If your trailer is brand new and recently purchased ideally you would return to the dealer to have the ramp corrected. The amount of misalignment you describe seems excessive for a brand new trailer. If the trailer is parked on uneven ground the ramp may tend to lean to the low side; this happens just from the weight of the ramp twisting the hinge. If the ramp leans over even on flat ground then there may be damage to the hinges that secure it to the trailer structure or the ramp itself...

  • 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...

  • Door Hinge Bracket with 4 Inch Width
    We don't have exactly what you are looking for. The # PLR1904-Z you referenced is 3-1/8 inch without the strap. The best other option is the Ramp Door Hinge - Steel # PLR1902 which utilizes as different hinge style and welds flat. It is 4 inches wide but without the bend. These are the only ramp door and dump door hinges we carry.

  • Recommendation for Trailer Ramp Hinge that Can Handle a 500 Pound Motorcycle
    For your ramp and 500 pound motorcycle I recommend using a couple of ramp hinges, # PLR1902, sold in quantities of 1. This is a heavy duty ramp hinge and has a grease fitting so you can easily keep It lubricated. I am not sure how wide your ramp is or the available space you have to mount a hinge but the overall length of this hinge is 8-3/16. For something a little shorter we have dump door hinge # PLR1904-Z which is under 5 inches wide. I have linked videos on both of these hinges for you.

  • Hinge Recommendations for a 5 Foot Ramp to Support a 1,000 Pound Load
    The piano style hinges such as # SH200 are fairly stout but what I recommend is a combination of a piano hinge and regular ramp door hinges such as # PLR1902. Since you will be putting a considerable amount of weight on the ramp you want everything to be as strong as possible. The ramp is going to have to be pretty heavy to handle the weight so even though the hinge won't be bearing all the weight of the ramp and the bike it still has to handle the weight of the ramp opening and closing....
