Expert Answers about Trailer Door Hinges


  • Hinge for Butterfly Gate That Allows 270 Degree Swing
  • While we do have a hinge that is going to let you have a gate that swings to the inside of the trailer and to the outside for a 270 degree swing, the hinges you referred to would not allow that type of movement. Instead, you will need what is called a square corner hinge, and you have a couple of different options based on the length and metal construction you want. The following options are below and I have added links to video reviews for you as well. - Square Corner Hinge with Reverse...

  • Dimensions Of The Over The Seal Strap Hinge # PLR2116-SS
  • The hole dimensions for the Over the Seal Strap Hinge are as follows. From the center of the hinge to the holes going down the shaft is 3-1/2", 9", and 14-1/2" respectively. So the measurement you're looking for is about 3 inches from the center of the hinge to the end of the bend. From the center of the hinge to the three holes on the bracket are 1-1/4" for both the top and bottom holes while 2-1/2" for the center hole. We do not modify, these are sold as is. We do have an aluminum one...

  • Ramp Hinge PLR1902 For Making Swing Out Trailer Barn Doors
  • The Ramp Door Hinge # PLR1902 that you referenced could swing out as far as you are needing so it would work well for you. The slide door bar lock assembly part # 305736 can also be cut down as needed as well. Then for a mechanism to lock the door open you could use a rubber socket and plunger set like the part # PLR64-66.

  • Weather Stripping and Drip Rail for Side Mounted Trailer Door
  • We do offer drip rail which we sell in 10 foot lengths as part # SR83FR. The rail would work great mounted above the door you mention, and would do a great job of keeping rain out of the top edge of the door. For the door edges, I'd use # SR92FR which is available in 15 foot lengths. I've linked to product description vides that you might find helpful.

  • Replacement Strap Hinge for Enclosed Cargo Trailer
  • It looks like the closest thing that we have to that design is the Square Corner T-Strap Hinge w/ Reverse Bracket # PLR4040, but if that doesn't work we do have a wide variety of other hinge straps that may work for your application like the part # PLR2216. I have attached a link to our selection of replacement strap hinges for you to check out.

  • Availability of Floor Escape Hatch for Enclosed Cargo Trailer
  • I can help you out with parts to create a hatch in the floor of your enclosed trailer, but we don't have an all-in-one kit for an escape hatch in your trailer. You'd need to make a cut out in the floor of your trailer and then you can use the Paneloc Butt Hinge # H418-204U to hold the door and the Trailer Rope Ring # RR02 as a handle. I also recommend using 1 or 2 of the RV Bolt Door Latch # 37220645 on the inside of the hatch to keep people from getting in from the outside. I'm attaching...

  • What Is the Weight Capacity of the Weld-On Hinge w/ Brass Bushing and Grease Zerk
  • The Weld-On Hinge w/ Brass Bushing and Grease Zerk part # MA79ZR doesn't have a listed weight capacity. That said, it uses a 5/8" diameter solid steel pin so the limiting factory would likely come down to the weld. The more hinges you have, the more support there will be but you'll have you use your best discretion as there is no listed capacity.

  • Does Continuous Hinge PLR844 Having A Load Rating?
  • I reached out to Polar who makes the Continuous Hinge - 8' Long x 5" Wide - Steel # PLR844 you were looking at does not have a weight capacity, but my contact there did mention if you are concerned that you can weld the knuckle on both ends which will keep the pin from being able to move which is the main failure point of a continuous hinge. The only way to know for sure if the # PLR844 will be strong enough is to install it, as hinges are not tested for specific loads due to quite a...

  • Can The Marlboro Continuous Hinge # MA74ZR Be Cut Down To Size
  • Yes, the 3" Wide Continuous Hinge - 6' Long - 1/4" Pin Diameter - Aluminum # MA74ZR can be cut down to fit your needs. I just recommend first removing the pin and separating each part before cutting them. You'll be better off cutting it at the end of the hinge loops, like I have pictured below, instead of trying to cut through them.

  • Recommended Hinge Arrangement for Swing-Up Side Mounted Door on Enclosed Trailer
  • According to the folks at TRC, the # 362100-955 hinge you'd looked at is intended for a downward opening ramp-type door that would have the load resting vertically on the spring. For an upward opening door, there would be nothing holding the door in place which would be dangerous because the door would become unhinged. A piano, or continuous hinge like # H300 would be a much better choice. You'll need to be sure to install a header of some sort above the door that's tied into the wall...

  • Weld On Hinges For a 70" Wide Trailer Door That Weighs 600LBS
  • I do have a solution for you as when I reached out to Marlboro Manufacturing who produces these piano hinges. They do not have any weight capacity ratings for their piano style hinges that you are looking at. They do offer their Weld-On Hinge with Stainless Steel Bushing and Pin # MA46ZR that will work well for your doors. They have a weight capacity of 648lbs per hinge, making a set of 2 more than enough capacity for your door.

  • Ramp Hinge Option for Aluminum Utility Trailer
  • I do have a good recommendation for you. We offer an aluminum ramp door hinge, that uses part # 362101-955 for the male and # 362100-955 for the female side. When slid together and cut to size if necessary, the hinge can be bolted or welded to to your trailer and attached to the ramp door. This would be a sturdier option than a piano hinge.

  • Can the Polar Door Hinge PLR1902 be Separated?
  • The ends of the Polar Ramp Door Hinge # PLR1902 are actually welded on, so they cannot be separated. However, we do have a few other options available for you. The Polar Dump Door Hinge # PLR1904-Z does use a bolt to hold everything together. There is still a zerk fitting to allow everything to be lubricated. It is quite a bit different, however, so the next option may be a better option. The Redline 3/4" Greasable Hinge # HP344G can be paired with # HPN342. This could then be adapted...

  • Thank you for the pictures! I may have an option for you, but none of the hinges we offer have mounting brackets that are 5" tall.. The most likely option we have is the # PLR4040 which opens 270 degrees. The mounting bracket on the # PLR4040 measures 3-7/16" long x 4-1/2" tall.

  • Which Piano Hinge will Work the Best on a Trailers Ramp Extension
  • Determining between piano hinges, # H300 3 Inch Wide Steel 6 Ft Long or # SH200 2 Inch Wide Stainless Steel Hinge 6 Ft Long, depends what features you find more important for your application. The # H300 hinge will be stronger in that it is an inch wider than the # SH200. Plus, the extra width will allow for more surface area on the hinge to mount to the trailer making for a stronger hinge. However, if weather conditions are a concern, the # SH200 is made of stainless steel. The stainless...

  • 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....

  • Why Doesn't Polar Hinge # PLR3408-PS Have a Weight Capacity
  • Polar does not give specific weight capacities for their hinges as the dimensions of the door would make a specific number too difficult to state as well as different applications might carry the weight differently. Like if you had a 20 lb door that was 2 feet wide vs. a 20 lb door that was 5 feet wide. The hinges would have more stress on them with the wider door due to the additional leverage. You'll have to use your best judgment but for a boat hatch two of the # PLR3408-PS would work...

  • 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.

  • Is a Piano Style Hinge Good for Making a Flap in a Trailer Ramp Door
  • Steel hinge # SH300 should work well for a flap on your trailer. You can't get a custom length but if you need 67 inches then # SH300 would be the one to get. You can trim it to the length needed. Between you and me, go with # H300. It is exactly the same only it is mild steel. The other one, # SH300, is stainless steel. That is why there is a big price difference.

  • Removing Rusted Hinge Pin on Trailer
  • You can try heating the nipple with a torch and then using a punch to drive out the pin. Be gentle with the heat, as the idea is to get the nipple to expand without heating the pin to the extent that it expands as well. When driving the pin out, be careful not to mushroom the end of the pin. For multiple hinges, you might have to remove the pins a little at a time. If that does not work, you will have to use an angle grinder to remove the nipple and pin completely, then start over with...

  • Hole Distance Dimensions of Cargo Trailer Strap Hinge Part # 2212
  • I was not clear on the actual dimensions you were needing, so I have provided a photo showing the hole dimensions. The distance from the hinge pin itself to the first hole on the strap is exactly 3 inches to the center of the hole. The distance between the two holes on the portion of the hinge that would install on the door jamb is 3-1/4 inches, center-to-center. These holes are 3/4 of an inch away from the hinge pin.

For example, the Square Corner T-Strap Hinge w/ Reverse Bracket # PLR2216-SSP is stainless steel and rotates 270 degrees. There are some other 180 degree options and aluminum construction as well.

  • Recommended 6 Foot Long Continuous Door Hinge for a Trailer
  • The best option we have for you is the Continuous Stainless Steel Hinge part # SH300. This hinge is 6' long, 3" wide, and has 1" long knuckles. The overall length of the hinge will be an exact fit but the width will be about 1/4" longer on each side in comparison to the one you have now. However, if this new hinge will not fit due to it being 3" long or 1-1/2" long on each side then you can always cut the excess width to make it work for you. The knuckle length should not really have any...

  • How To Confirm Fit and Install 5-1/2" Long Strap Hinge
  • The Strap Hinge part # PLR104SS is a universal trailer door hinge. The best way to determine replacement is based on length which for this model is 5-1/2" long. The hinges can be riveted or screwed on. If your old one has rivets they will need to be drilled out to remove them. The new one then can be attached with screws for an easier install or a rivet gun if you have one. Please note, we don't have any info on the door hinge on your trailer currently so measuring is best to determine...

  • 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.

  • 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.

  • 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.

  • Can Hinge Pin # HP34412G Be Used on Dump Trailer
  • While the Hinge Pin # HP34412G doesn't list an official weight capacity, it's 3/4" steel construction features a really high shear strength (well over 2,000 pounds). With this in mind it should be plenty capable for use on your dump trailer.

  • Can a Piano Style Hinge be Used on a Trailer Ramp Door that is 94 Inches Wide
  • The way a trailer ramp door is hinged is going to depend on how the manufacturer decides it needs to be hung so it really could be one long piece or several pieces. The hinge(s) may or may not extend all the way to the edges but most of the ones I have seen do extend the length of the door. Piano hinge # H300 is decent sized. It is 3 inches wide so it is a pretty good size. It wouldn't be used on a heavy equipment trailer or anything like that but instead be used on smaller enclosed...

  • Can Barn Doors of Trailer Ramp be Changed to Ramp Door
  • Most likely it's possible but the level of modification you'll need to do is hard to say. We have ramp door hinge kits like the part # PLR1904-Z which you'd weld to the back of the trailer and then attach a ramp door to. But most likely you won't be able to reuse the barn doors and you'll have to come up with a ramp.

  • 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...

  • Load Capacity of Polar Strap Hinge for Enclosed Cargo Trailer Doors 2212
  • There is no specific weight capacity listed for the Polar Strap Hinge for Enclosed Cargo Trailer Doors # 2212. I confirmed this with Polar. When replacing an existing hinge on an enclosed trailer you will want to match the general size and number of hinges originally on the door. This item uses heavy 8-gauge steel material and so it will be up to the task of supporting a trailer door so long as it is roughly the same size as the original. If your door had three hinges of this approximate...

  • The Strap Hinge for Trailer Doors, part # 2512 do not have a weight rating listed. These are made of heavy-duty 8 gauge zinc-plated steel and measure 12-inches long. For a heavier door you may want to use an additional hinge to make sure they can handle the weight.

  • Weight Capacity for Polar T-Strap Hinge # PLR4040
  • According to our contact at Polar Hardware their T-strap hinges like the 12-3/8 inch # PLR4040 that you referenced don't have a specific weight capacity. Your limiting factor is really going to be the hardware that is used to mount the hinge and not the hinge itself. If you are simply replacing existing hinges on a trailer you will just want to use the same number of hinges that you currently have.

  • Do Polar T-Strap Hinges # PLR4040 Have Weight Capacities
  • We've checked with Polar in the past about whether the T-strap hinges like the 12-3/8 inch # PLR4040 have weight capacities and they've stated that they do not rate them for weight as the mounting hardware would be the limiting factory. That said, as long as you are using this in a "reasonable" application you can use your best judgment whether these would be rated high enough or not.

  • Recommended Strap Hinge to Replace Continuous Hinge on Enclosed Trailer Door
  • I recommend going with the Polar Wide Bracket Strap Hinge # PLR2008-AS. The strap is 8 inches long and has 3 holes to install on the door as well as 3 mounting holes on the bracket. The hinge is also made out of aluminum so it will have superior resistance to rust and corrosion than most other hinges. If you go with 3 of these along the top, midsection, and bottom of your door it will help to keep your door intact when gusts of wind comes. I have attached a review video of this hinge...
