This is a stainless steel boat trailer leaf spring shackle. It measures 2 1/2" from center hole to center hole and has an over all length of 4" with a hole diameter of 1/2". The shackle strap is made from 1/4" thick stainless steel plate to prevent rust in salt water environments. These shackle plates are used to hang a double eye springs on a trailer. They mount on the rear of the spring allowing the spring to lengthen as it absorbs bumps. They are also used in tandem axle trailers to attach the front and rear springs to the middle equalizer bar. Single axle trailers will use 4 spring shackles (2 on each side). Tandem axle trailers will use 8 spring shackles (4 on each side). This is the most common length spring shackle.

On single axle trailers, a longer leaf spring shackle will increase the ride height of the trailer, and a shorter will lower the ride height. 
On a Tandem Axle Trailers, a longer leaf spring shackle will lower the ride height of the trailer, while a shorter shackle will increase the ride height.

These Galvanized shackles are more commonly used on Boat trailers. However, they can be used will all types of trailers. With slightly larger than 1/2" drilled holes, these leaf spring shackles are used in conjunction with 1/2 inch diameter Leaf Spring Mounting Bolts

These plates can also be used as frame plates on the bottom of u-bolts, or as general brackets. For this purpose, this shackle will accept 2 inch wide u bolts.
