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 have an older "Lark" trailer that had 3 hinges similar to these ramp door hinges I purchased from e-trailer. Two out of three had broken over the years. Lark was of no help when I contacted them. I went to several places that are known here in Orlando for trailer repair. They want a kings ransom to replace them. So, I located these hinges on e-trailer.com I ordered them and they were promptly delivered. Examined them closely and they are well made, and also have the grease nipple for keeping them lubricated. A local metal shop came and welded them on my trailer. These hinges are perfect. If you have a car-hauler or any trailer for that matter - you won't be disappointed in these hinges. No, I was not paid for this endorsement - and I did paid full price for the hinges. Good value for my money.



by:

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.

Super sturdy hinge! Worked great for the ramp door on our toy hauler.

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.

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..

Product is exactly what I needed, great communication and great service. Appreciate your excellence.



by:

This was exactly what we needed to complete our custom landscape truck ramp.



by:

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.

See what our Experts say about this Polar Hardware Trailer Door Hinges

  • Hinge that Can be Used on Legend Trailer Ramp
    The Polar hinge part # PLR1902 would be a great option. This is a heavier duty hinge that would easily do the job.

  • Ramp Door Hinges for Toy Hauler
    For your butt hinge, I recommend using the Paneloc 5 Knuckle Butt Hinge - 2-1/2" Long x 2-1/2" Wide - Stainless Steel # H674-200U. The pin diameter is 3/16 inch. You may want to use more than 5 depending on the weight you will be placing on that ramp door. For most toy haulers, a better option is to weld on the Polar Ramp Door Hinge - Steel # PLR1902, which has a built in grease zerk for easy maintenance. This is my recommendation for a stronger hinge for a ramp door.

  • Hinge Recommendation to Make Fold Down Stage on Trailer
    Yes, the hinge part # PLR1902 will work well for you. If you used 6 of these on a fold-out style stage it would have the capacity needed and would operate well for you.

  • 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.

  • Recommended Ramp Hardware to Add Ramp to 2002 Sundowner Gooseneck Horse Trailer
    We do not have the Ramp you need, but we do have the hardware you would need to add a ramp to your 2002 Sundowner Gooseneck Horse Trailer. You will want a ramp door hinge like the Polar # PLR1902. You will weld the outside cylinders of the hinge to the trailer and the center section will be welded to the ramp you are adding. Another option is to use the 3" Wide Continuous Stainless Steel Hinge, 6' Long # SH300. To hold the ramp in place for travel, I recommend the 36" Lock Side-Door...

  • Availability Of Weldable Ramp Door Hinge Which Allows Ramp Door To Be Removed On a Utility Trailer
    The only ramp door type hinge we have that is weld on with a removable pin is the Aluminum # PLR1005. While the Ramp Door Hinge # PLR1902 you found does not have a removable pin you could weld it to a removable plate on the trailer which would then allow you to remove the entire ramp along with the hinges.

  • Does The Polar Hardware Ramp Door Hinge Come In Pairs Or As Single Units
    The Ramp Door Hinge - 8-3/16" Long - 1" Pin Diameter - Steel # PLR1902 comes as a single unit. Quantity of 1. So if you need two or more you will need to make sure you change the quantity bought to reflect the amount you need.

  • Would Ramp Hinges PLR1902 Work as Replacement for H and H Trailer
    The ramp hinges part # PLR1902 don't have a specific weight rating, but I can tell you that by the sheer size of these things and their steel constructions that three of them would be just fine for a 4,000 lb rated ramp.

  • 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....

  • Does The Ramp Door Hinge # PLR1902 Have a Solid Hinge Pin?
    Yes, the Ramp Door Hinge # PLR1902 has a solid 1/2" steel internal pin that passes all the way thru the hinge.

  • Finding The Correct Ramp Door Hinge For A 2011 12' x 6' Mirage Cargo Trailer
    It is quite possible that the # PLR1902 hinge will be correct for your 2011 12x6 Mirage cargo trailer. These hinges are not custom fitted, so generally we like to get either measurements or pictures of the current hinge in order to recommend a replacement. That being said, this hinge is pretty much universal, and it is made for use with a ramp door. It is 8-2/16" long overall with a 4" long bracket. If you can measure out the current hinges this will tell us what will fit and what wont.

  • What Could Cause Ramp Door on Enclosed Car Hauler to Become Out of Line
    It is difficult to say what exactly may have caused the ramp door on your enclosed car hauler to come out of alignment. It could be a bad hinge or something could have been damaged on the door itself with the previous owner, which over time lead to the door coming more and more out of line. We do offer some ramp door replacement parts, such as the Polar Hardware Ramp Door Hinge # PLR1902 if you find that the hinges should be replaced. I have included a link that will take you to our available...

  • Does the Polar Ramp Door Hinge # PLR1902 Have 2 Plates for Welding
    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.

  • 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...

  • Replacement Spring And Hinge Options For A 2008 Jayco Recon ZX 37U Toy Hauler Ramp Door
    Our ramp door hinge selection is limited to just part # PLR1902, which can be welded in place. As for the springs, we have a bit of a selection that you can narrow down depending on the width of the ramp door and the capacity needed. For example, part # M394FR can fit a door width of 67-3/4" to 95-1/2" and has a spring capacity of 185lbs. I've attached a link below to our spring options.

  • 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....
