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.

Ask the Experts about this Polar Hardware Enclosed Trailer Parts

Do you have a question about this Enclosed Trailer Part?


  • 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.
    view full answer...

  • 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.
    view full answer...

  • 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.
    view full answer...

  • Recommended Hinges And Ramp Assist For Steel Ramp
  • For your ramp, I recommend a hinge like the Ramp Door Hinge - Steel # PLR1902 or the Dump Door Hinge - Steel # PLR1904-Z. Both of these have a built in zerk grease fitting. Then you can use springs like # RS16933RH and # RS16933LH. If you want further help in lifting and lowering, I recommend the Rack'Em Double Barrel Utility Trailer Tailgate Lift Assist w/ Chain - 200 lbs # RA-27C that can be used on either side or both.
    view full answer...

  • 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...

  • 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.
    view full answer...

  • Installation of Ramp Door Hinge Polar 1902
  • The Ramp Door Hinge # PLR1902 does require welding of both portions. The tab gets welded as you stated to one side and the outside cylinders get welded to the opposite side. I've attached a couple pictures to assist.

  • Dimensions of Polar # PLR1902 Steel Trailer Ramp Spring
  • The entire hinge is 8-3/16 inches long by 1 inch in diameter. If you take a look at the photo I've edited for you, you can see all the dimensions of the Polar Steel Ramp Hinge, part # PLR1902.

  • 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...

  • 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....

  • 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.
    view full answer...

  • 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 Door Hinge For 6 X 12 Enclosed Trailer
  • Thanks For the photos of your hinges. That helps a lot when we are trying to find something for a customer. I have attached a photo of a hinge, part # PLR1902 that may work for you. You can check out the photo and see the dimensions for the hinge. The hinge measures 8-3/16 inches long, the end pieces are 1 inch in diameter, and the plate portion measures 4 inches wide by 2-5/8 inches deep. This hinge is made of steel and even has a grease fitting to keep it lubricated for smoother...

  • Capacity of Polar Enclosed Trailer Door Hinge
  • The Ramp Door Hinge # PLR1902 isn't tested for a specific weight capacity. However, it is intended to be used on heavy trailer doors.

  • Diameter of Post on Ramp Door Hinge # PLR1902
  • The diameter of the post on the Ramp Door Hinge # PLR1902 that you referenced is 1 inch. I attached a picture that has several other dimensions for you to check out as well.
    view full answer...

  • Do Any of the Continuous Hinges Have a Weight Capacity
  • Polar doesn't have any weight ratings on their hinges, but if you alternated the use of a continuous hinge, like part # H300, and a Ramp Door Hinge, like part # PLR1902, it should work well under the 800 lb load you mentioned. I confirmed this with my contact at Polar . Attached is a list of our available door hinges for you to reference as well.
    view full answer...

  • 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....
    view full answer...

  • Replacement Ramp Hinge Recommendation for Trailer
  • For a set of ramp hinges with a grease fitting the part # PLR1902 would work well for you. Overall the hinge measures 8-3/16 inches long, the end pieces are 1 inch in diameter, and the plate portion measures 4 inches wide by 2-5/8 inches deep. I attached a review video for this hinge for you to check out as well.

  • 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...

  • Are Ramp Door Hinges for Trailer Available?
  • We do carry ramp door hinges though they are not made specifically for a Snowpro trailer. The ramp door hinge # PLR1902 is steel and gets welded on; I've added a photo showing the dimensions of this hinge as well as a link to a video review for you to take a look at and a link to our selection of hinges.

  • 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.

  • Recommended Ramp Hinge to Support Weight of Ford 4000 Tractor
  • I recommend looking at the Polar Ramp Door Hinge # PLR1902. This is a heavy duty steel hinge that features a plain finish for easier welding and also includes a grease fitting to allow for a longer life and smoother operation. This hinge does not have a specific weight rating, but 3 of the hinges on your ramp door will be more than enough to support the weight of your Ford 4000 Tractor. I have attached a short video demonstration on this product that you can also check out.

  • Is Hinge Pin of Polar Ramp Door Hinge # PLR1902 Removable?
  • The Polar Ramp Door Hinge - Steel # PLR1902 is not removable as removing that pin would compromise the zerk grease fitting and seals related to it. I confirmed this with my tech contact at Polar.
    view full answer...

  • Pin Diameter on Polar Ramp Door Hinge # PLR1902
  • The Polar Ramp Door Hinge # PLR1902 referenced in your question has a 1/2 inch internal pin diameter. As you mentioned, the outer diameter of the hinge is 1 inch. The steel hinge also features a grease fitting to allow for a long life and smooth operation. I have attached a short video demonstration on this product that you can also check out.

  • 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...
