These where a direct replacement for what was originally on my trailer. They bolted right on.

These are great hinges. I have purchased these several times, utilizing them when constructing Dutch barn stall doors and large shed doors. These hinges dont sag, the zinc has been in the weather for a year with no rust unpainted. Dont waste money on other hinges. This is your best choice at a low cost.

  • Is a 90 Degree Hinge Rotation on a T-Strap Hinge Normal on a Trailer
    The hinge rotation is going to depend on the design of the T-strap hinge. For example, the Square Corner T-Strap Hinge w/ Reverse Bracket # PLR4040 is capable of a 270 degree rotation based on its design. The # PLR3408 only allows for 180 degrees of rotation. Unless something else is blocking them or limiting the movement, it is likely that 90 degrees is the limit of the hinges you currently have.

  • Hinge Mounting Hole Dimensions & Spacing Measurements
    I went to our warehouse and measured the Polar Polished Stainless Steel T-Strap Hinge # PLR3408-PS to get the dimensions you need. The two holes on the square/door jamb end of the hinge are 3/8-inch in diameter. Their center-to-center hole spacing is 3-3/16-inches and their outside-to-outside spacing is 3-5/8-inches.

  • Dimension Of The Polar T-Strap Hinge For Trailer Doors
    The T-Strap Hinge for Side and Rear Trailer Doors - 8" Long - Stainless Steel # PLR3408-SS is a nice corrosion resistant hinge. The measurement you asked for of the flat part of the bracket is the 1-5/8 inches you mentioned. If you include the pin it is about 2 inches. You can see these measurements in the attached video as well as a few others you may find helpful.

  • Hinge Quantity For Side or Rear Trailer Doors
    The T-Strap Hinge for Side and Rear Trailer Doors - 8" Long - Stainless Steel # PLR3408-SS is a single hinge. You will simply want as many of them as needed for the weight of your trailer door to not sag. Most doors will use 3 but I've seen up to 5 hinges depending on the thickness of the door.

  • 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...

  • 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.

  • Polar Hinge for 90 Degree Corner Compatibility
    The T-Strap Hinge for Side and Rear Trailer Doors - 8" Long - Steel # PLR3408 will not be ideal for a 90 degree corner as you can see the purposeful bend at the hinge on the strap end of the hinge that would limit this. A better option for that application is the T-Strap Hinge for Rear Trailer Doors - 12-3/8" Long - Steel # PLR4040, the Square Corner Hinge with Reverse Bracket - Polished Stainless Steel - 12" # PLR2212-SSP, or the Over the Seal Hinge - Narrow Bracket - Aluminum - 12" #...
