This 12 inch Hot-Dipped Galvanized Swivel Top Bunk Bracket kit is designed for boat trailer bunk board set ups that commonly use Bunk Board 2 in x 4 in sets and also to adjust the angle to the contour of the boat hull. Typically, these adjustable swivel bunk board brackets are mounted to cross members in front and behind the axle, a common single axle trailer might have (4) of these. These galvanized 12 inch Bunk Brackets have slotted 1/2 inch diameter holes to accommodate 1/2 inch Trailer Bolts or Boat Trailer U-Bolts and comes with a zinc plated 7/16" x 1" bolt to mount the top bracket. The slotted holes allow you to adjust the height of the bunks. We offer these in 10 inch Bunk Bracket Swivel Top and 8 inch Bunk Bracket Swivel Top  if you need a different height for your adjustment. The 12 inch measurement is the length of the bracket itself.
Keep in mind when replacing the entire Swivel Top Bunk Bracket you commonly will also need new mounting Bolts or U-Bolts, and also may be needing replacement Bunk Bracket Lag Screws to re-mount your bunk boards if you are using a 2 x 4 or 2 x 6. There is an image that shows a Model of a Swivel Top Bunk Bracket attached to a 3 by 3 Cross-Member using a U-Bolt (This Does not represent how every swivel top is mounted, but just shows an example.) These Swivel Top Bunk Brackets are also commonly mounted to cross members that are C Channel in shape and have different dimensions. Measure your frame dimensions, or simply measure your previous U-Bolts if you are replacing with the same setup!
It is also not uncommon to see these towards the front of your Boat trailer as a second set of bunk guides for the bow of your boat. With this arrangement, you will usually have shorter lengths of 2 x 4 or 2 x 6 that are spaced closer together.

Purchased these bunk brackets to use on a old boat lift my son rebuilt for my family. Put it in the water last weeked and these brackets that we used to build the bunks work great. From a $60.00 used boat lift to replacing some of the steel, new bolts and adding bunks, has made a great end product. Holds my 1800lb boat well.
