This product is a solid 6 inch Aluminum L-Shaped Bunk Bracket support for your Boat Trailer. This Bunk Bracket measures 6 inches tall and 5 inches wide. The Holes you see on the longer section and foot section are 1/2 inch in diameter. The thickness of this 6 inch Aluminum bunk bracket is 1/4 inch for maximum strength. The foot holes are designed specially to be mounted on a 3 inch wide cross member. In most, if not all cases the cross-member would measure 3 inch by 3 inch. This style bunk bracket is used to mount bunk boards vertically to support the hull of the boat. 
If you are deciding on this 6 inch L-Shape Aluminum Bunk Bracket you are either replacing existing rusted bunk brackets or switching the style of bunks on your boat trailer. 
When replacing existing rusted L Shape bunk brackets of the same style and switching to this aluminum bunk bracket, keep in mind you need to use equally durable hardware. It is very common to see Galvanized Bunk Brackets, when replaced, eat through the aluminum cross-member slightly, this also happens with the U-Bolts when galvanized U-Bolts are used on aluminum. To permanently prevent this problem, use Stainless Steel U-Bolts to mount your Aluminum Bunk Bracket to your Aluminum cross-member. If you are mounting this 6 inch L Shape Bunk bracket to a 3 inch by 3 inch cross-member, the correct stainless steel U-Bolt is  Stainless Steel U-Bolt 1/2 inch x 3 inch x 4 5/16 inch. This size U-Bolt will ensure the proper length of threads. Be sure to double check the U-Bolt dimension you require. These U-Bolts are also available in Hot-Dipped Galvanized. 
In addition, you will need through bolts to re-mount your bunk boards. Check the length bolt you need. We have these available in both Stainless Steel and Zinc plated, you will need a 1/2 inch diameter bolt. Trailer Bolts
These bunk brackets typically are replaced in pairs, so keep that in mind! 

 L Type Bunk Bracket Kit To Do List:
   Boat Trailer U-Bolts are used to mount your Swivel Top Bunk Bracket to your trailers Cross Member, determined by measuring the width and height, and selecting between galvanized or stainless steel hardware.

Boat lights
Because of the shape of the top of our boat, the light bar we bought didn’t clear the top with the brackets included. We needed 6” of distance to install safely. The cost of making two brackets to fit was nearly $200.00. I found these boat trailer parts that fit perfectly. Although not for the purpose intended, they are a beautiful fit and much sturdier than the original.
