This heavy duty hat bracket is an ideal replacement for boat trailers. Made out of 3/16” thick hot dipped galvanized steel, it can be used in conjunction with a V-guide set up or bunk board supports. Typically this item will fit on a trailers cross-member that is 3”x 3” square tube. The hole spacing center hole to center hole measures 3 5/8”. You will need to use a u-bolt that is 3” wide on the inside. This hat bracket is used to clamp front v-guides or bunk boards that use 2" x 2" square tubing for their support.
This version of hat bracket is also used as a clamp and support for 2" x 2" square tubed bunk brackets on some brands of boat trailer. If you are mounting this bracket to a 3" x 3" cross-member, which is almost always the case, you would need either the Galvanized U-Bolt 1/2 inch x 3 inch x 4 5/16 inch or Stainless Steel U-Bolt 1/2 inch x 3 inch x 4 5/16 inch to mount to your trailers cross beam.
