Great trailer door replacement hindge I ordered 3 thinking they would not hold the weight of my ramp door on my sled trailer after welding two in place i think the third was overkill. Easy to use worked like silk great thing with the zerk fitting for grease every season. 9816

Installed a yr ago. Perfect product. One thing for me though.... I had to buy different fenders because I bought better tires and rims for this new axle which turned out to be slightly wider. So the original fender would have cut into the tires. I got everything from etrailer. Axle with brakes fully assembled, controller, fenders, wire harness, connections tires, time and more...and couldn't be happier with cust service, pricing and availability. 426127

Very simple design worked great welding was easy more than enough metal to attach to frame of trailer and greasable solved many issues while designing a trailer gate 568855

The application I used these for was a perfect fit to my trailer. They perform better than I could have ever imagined. Thanks!

I was astounded that my hinges showed up in the same week I ordered them, and I was very pleased with the quality of the parts, especially have the zerk fitting option!! The choices were abundant but these are similar to what seized up on my own trailer and ripped the skin of the trailer, so these will be a quick fix for my welder. Thanks for the prompt service!

This low profile but strong hinge really sets off the crisp oak tailgate for the home rebuilt utility trailer. Coupled with some 2 in angle screwed into 5/4 rough oak, allows right offset to lower hinge body below deck line for welding onto rear box tube. Gate pulls off and leaves nothing protruding for sliding in cargo. Also, then it leaves a great positive secure engagement point for motorcycle ramp attachment. Sweet product! 167406

I think these will do what I want! My trailer came with a non removable drop gate. At times I would like to take drop gate off so I can get a wheel barrel close to shovel mulch into it. I believe I should be able to weld these on the cut original hinges off allowing that to happen! 638486

Ask the Experts about this Redline Enclosed Trailer Parts
Do you have a question about this Enclosed Trailer Part?


  • Recommended Gate/Ramp Assist and Hinge for Trailer Build
  • The 2K Torque Ramp Spring # RS16933RH is an industrial strength spring. It is designed for up to 90 degrees of deflection, but most people by hand can cause no deflection at all. It is designed to be used with the LH # RS16933LH, and is for heavy ramps or doors like in the attached photo. I would assume it is too strong for your application based on your wording. You may want to consider a different style spring like the Enclosed Trailer Ramp Spring - Dual Spring, 81" Wide # ERS120D81...

  • 6 inch Long Trailer Hinge that is 3/4 inches in Diameter
  • For a 6 inch long hinge setup that has a 3/4 inch diameter you would want the part # HP34G and # HPN3342. These two pieces together will give you a hinge in the dimensions you requested.

  • Ramp Hinge Recommendation for a Replacement Hinge for an Enclosed Trailer
  • A piano hinge like the part # SH300 could work very well for a replacement hinge for your enclosed trailer. This hinge is 6 feet long and 3 inches wide. A co-worker here used 3 of the Greasable Hinge Pin, # HP12412G, for a similar application and that is what he recommends using over the piano hinge.

  • Will the Redline Greasable Hinge Pins HP12412G Fit on a 2006 Gearbox 335FS Toy Hauler
  • The Redline 1/2 Inch Greasable Hinge Pin, # HP12412G, is a great option to replace the missing hinge pins on your 2006 Gearbox 335FS toy hauler. These hinges are a universal fit item and include a grease zerk fitting for easy lubrication. If only some of your pins are broken, then you may want to measure the sizes of your remaining hinge pins so you can purchase the correct size replacements. We carry 1/2 inch and 3/4 inch hinge pins. I have attached a link to all of the hinge pins we...

  • Weight Capacity For Redline 1/2 Inch Greasable Hinge Pin
  • I called my contact at Redline and they told me that the weight capacity for the 1/2 inch Diameter Greasable Hinge Pin, part # HP12412G is 420 lbs. They did stress the weight capacity can vary due to the installation. They recommend using a certified welder to attach the hinge and to make sure there are enough hinges installed to be able to handle the weight of the gate or door it is being used on. I have attached a link to a product review for this hinge you can check out.

  • Are There Other Parts Needed When Installing a Greasable Hinge Pin # HP12412G
  • You will not have to purchase 1/2 inch Diameter Hinge Pin Nipple # HPN214 to install a 1/2 inch Diameter Greasable Hinge Pin # HP12412G. The # HP12412G already comes with a base with a grease fitting, so the # HPN214 would not be necessary. Check out the pic I attached that shows the grease zerk fitting on the # HP12412G

  • Recommendations for Converting a Barn Trailer Door to a Ramp Door
  • To convert your barn door on your Wells Cargo enclosed trailer to a ramp door I would recommend you use the Universal Cam-Door Lock for Enclosed Trailers # 383200 that you referenced as well as a 3/4 diameter pipe that you will need to get from a hardware store. For a hinge mechanism, if the current hinges you have are not adequate, I would recommend you get three 1/2 inch Diameter Greasable Hinge Pins # HP12412G to use as door hinges. You might also be interested in purchasing a...

  • Using 1/2" Diameter Greasable Hinge Pins to Make a Detachable Ramp
  • On the 1/2" Diameter Greasable Hinge Pin, 4-3/4" Long with 3/4" Base Item # HP12412G you would need 2 sets and they would have to be facing the same way in order to make the ramp detachable. But yes, you could do it.

  • Diameter of the 1/2" Diameter Greasable Hinge Pin
  • The part # HP12412G is 4-3/4 inches long overall not including the grease fitting. The outside diameter is 3/4 inches. That is the portion of the hinge that gets welded to a trailer. The inner portion that inserts into the other part of the hinge is 1/2 inch.

  • Are Trailer Ramp Hinges Friction Fit To Each Other
  • To separate the sections of the 1/2" Diameter Greasable Hinge Pin # HP12412G that you referenced you would not have to pound on them with a sledge hammer. That would imply to tight of a fit for the hinge to swivel and function. If you check out the review video I attached you will see how easily the two pieces slide into each other. Normally to remove hinges you have to separate one side of the hinge from either the door or the opening so that the two pieces can slide out from each...

  • Can Stainless Steel Hinge, # SH300 be Used as the Hinge on an Enclosed Trailer Ramp and Door
  • While it is possible that the Stainless Steel Hinge, # SH300, will work for your application, I believe that there are better and more reliable options. A co-worker here used 3 of the Greasable Hinge Pin, # HP12412G, for a similar application and that is what he recommends using over the piano hinge.
