My buddy Kevin had a hard time finding the perfect hinge, so I found this one, it was perfect for two projects. The first one was for the boat's radar mass,to tilt it, and the other two was for the engine cover for his boat. We are thankful for the quick response from the company for shipping all three hinges,to which, arrived sooner than the expected time. Thanks etrailer.

Great substitute for 'frozen' Merhow Horse Trailer door hinge.


Excellent Great Quality Heavy Duty I Drilled Holes Bolted And Welded Them On Trailer They Have Been On Trailer For A Year No Issues


These are great hinges. The only complaint I have is that they aren’t flat but folded and spot welded. I’ll have to take some 3/16” aluminum and cut spacers to create a flat area. Other than that, they will be great hinges for my drop down table on my swing out bumper.


Great thanks


Sturdy aluminum hinge.


Easy fix to my door problem!

  • Can Aluminum Door Hinge PLR1005 be Used as a Hinge for a Trailer Ramp
    Hinge # PLR1005 could work but you would need to use several of them. this is because this is a door hinge and a ramp will be heavier. That could be why you are having problems with the existing hinge(s); there just aren't enough to support the weight. But if you used 4 of # PLR1005 then that should support the weight. The more the better!

  • Wall Thickness on Polar Hardware Butt Hinge # PLR1005
    The Polar Hardware Butt Hinge # PLR1005 referenced in your question features a 3/16 inch thick aluminum wall on the eyelet and it will accept a 1/2 inch pin (which is included). We do not have a similar hinge available that with a smaller 1/8 inch thickness.

  • Does the Polar Butt Hinge-Aluminum Have a Weight Capacity
    The Polar Butt Hinge- Aluminum # PLR1005 is not rated for a specific weight according to the manufacturer. We've seen customers using 3-4 of these on ramp doors that weigh 500-lbs or so, so using 4 of them on your trailer tongue might work depending on how heavy the trailer and the tongue weight. If you can tell me some of the weights you're dealing with, I'm happy to give you a more precise answer.

  • Does Polar Aluminum Butt Hinge Hold Together with the Pin?
    The Polar Butt Hinge - Aluminum # PLR1005 will be 2 separate plates when the pin is pulled out. To replace the pin, you will need to line up the two sides and place the thrust washer in place to keep the friction to a minimum. You can weld these or drill them and use screws to attach. Being aluminum they have a much different melting point than steel.

  • What is the Weight Capacity Of The Polar Aluminum Butt Hinge?
    The Polar Butt Hinge - Aluminum # PLR1005 is not weight rated so I can't confirm a weight amount for you. These can be used on a fold down platform like you mentioned and have been according to some of our customers. The more hinges you use, the stronger it will be. I suggest using 4 for your application.

  • Recommendations for a Removable Weld-On Trailer Ramp Hinge
    For a weld-on hinge for your utility trailer ramp, the best option is the Butt Hinge w/ Removable Pin - 5" Long x 4-7/8" Wide - 1/2" Pin Diameter # PLR1005. This hinge comes with a removable pin which allows for you to easily mount and remove the ramp when not in use. Since the hinge has no bolt holes, it is perfect for welding applications. Each # PLR1005 comes with a single hinge, so you most likely need additional hinges for your setup depending on the dimensions of your ramp. I went...

  • 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....

  • 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.

  • Aluminum Hinge for a Utility Trailer Tailgate
    We do have an aluminum hinge for you. While the Dump Door Hinge, part # PLR1904-Z, only comes in steel, the Butt Hinge from Polar Hardware, part # PLR1005, is an aluminum construction. It can be welded or bolted to your tailgate. I've linked to a video review of this hinge for you to look at.

  • Determining Correct Replacement Door Hinge For 2000 Sooner Royale Horse Trailer
    I would be happy to help you find the correct replacement door hinge for your 2000 Sooner Royale Horse Trailer, but I was unable to find any dimensions or information about the 03139010 hinge you mentioned. Based on the picture you provided it looks like a hinge like the T-Strap Hinge for Side and Rear Trailer Doors - 8" Long - Polished Stainless Steel # PLR3408-PS would work, but you will want to confirm the mounting hole dimensions. The # PLR3408-PS measures 3-1/4" on center of the...

  • Replacement Door Hinges for a 1990 Sooner 2H Slant Horse Trailer
    I recommend replacing the hinges on your 1990 Sooner SH slant trailer with the T-Strap Hinge # PLR3408-SS. These hinges are stainless steel for increased life and are stronger than the aluminum hinges you currently use. They are also have a larger mounting pattern than the Butt Hinge # PLR1005 you are looking at as a replacement. This will ensure the hinge has sufficient surface area on the door to support the weight of the door.

  • 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.
