This bolster-and-swivel-bracket assembly supports your boat trailer's bunk board and enables it to be tilted to the proper angle. It resists corrosion and features slotted mounting holes that let you adjust the height during installation.
Bolster and swivel bracket assemblies are typically mounted upright on a boat trailer's crossmembers. They allow a mounted bunk board, which is run from the front of the trailer to the back, to pivot while you are loading a boat. On kayak trailers, these brackets are mounted to the trailer's frame and support bunk boards that run across the trailer.
Galvanized steel parts are hot-dipped in zinc after being stamped. This creates a coating that is typically 3 mil to 5 mil thick. This thick, all-around coating allows galvanized steel products to provide years of use without rusting or corroding.

I'm new to boating & trailers, am just a do-it-yourselfer, and found etrailer online. The trailer I am refurbishing for my son, was built in 1974. The main bunks were supported by angle cut 2"x4"s bolted to the trailer frame. They did not swivel, were not adjustable. I replaced these with the CE Smith bolster and swivel bracket assemblies. These arrived very quickly, and were perfect for my application. They are easy to install, just two 1/2" diameter carriage bolts with cut washers & lock washers per bracket assembly, and you're done. These can be adjusted for final set up to cradle your boat. They're very sturdy, and galvanized for corrosion resistance. Now, I did also replace the original bunks, using 8' pressure treated 2x6"s, that I covered with outdoor/deck carpeting, stapling the carpet to the boards underneath. My mistake, which the picture shows, was putting carpet on one bunk before the holes were drilled & the mounting 1/2" carriage bolts were installed. Rather than removing the carpet & starting over, I just cut the carpet & folded it back where the mounting bolts would go. Once the bolts were in, I just glued the carpet back down with waterproof contact cement. I also chose to put the bunks loosely onto the top of the mounting brackets, after bolting them to the trailer. I used a mechanic's creeper to roll underneath and triple check then mark the drill holes on the bunks, to assure a good alignment for drilling the mounting bolt holes on the bunks, before finally drilling for & mounting the bunk bolts. This worked great, the bunk mounted perfectly to the brackets. The brackets do come with locking nuts on the swivel part, that needs to be tightened down into the final position, to allow the swivel without too much wiggle. Great product, etrailer/ customer service is the best!100865

I received my bunk board swivel brackets faster than I expected. The quality is very good and should hold up for many years of use. I haven't installed them yet but as I go through this boat/trailer restoration I expect to order more products from etrailer. Fast and easy, that's what I like!91736
