CE Smith double U-bolt bolster brackets installed on a boat trailer

Bolster-and-swivel-bracket assemblies are typically mounted upright on a boat trailer's crossmembers. They allow a mounted bunk board, which runs from the front of the trailer to the back, to tilt to accommodate and support boat hulls of different sizes. On kayak trailers, these brackets are mounted to the trailer's frame and support bunk boards that run across the trailer.

Galvanized Steel

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 just got my bunk board brackets, they look like they will work great. I was very happy with the service I received, I will not hesitate to use etrailer.com again. 276172

Received the order, on time, and exactly as listed. Would purchase from etrailer again. 167359

- CE10196G-4

Very well made, heavy gauge steel with what appears to be a well done galvanization. Should do well in salt water launches. They are tall enough to give me 15 inches of clearance measuring a straight line across the bunks and drop a plumb line at center to the keel roller. My only gripe is that the supplied bolts for the top swivel bracket are only 3/8 and regular nickel plated grade 5. The holes are clearly 1/2 inch so I put in my own galvanized 1/2 inch bolts with lock washers. 151292


Ask the Experts about this CE Smith Boat Trailer Parts

  • Compatibility of Boat Trailer Roller Bunks with CE Smith Swivel Bracket Assemblies # CE10196G-4
    If your Dutton Lainson roller bunks have a flat bottom surface like part # DL21741 then you can mount them directly to the CE Smith Bolster and Swivel Bracket Assemblies # CE10196G-4 as shown in the linked photo. These are the tallest ones we offer. If the bunks have an open channel in the bottom, like part # DL21755, then you will want to first mount the bunks to a 2 x 4 bunk board which will fit into that channel and then mount that to the brackets.

  • Do Trailer Roller Bunk Brackets like CE10196G-4 Have Weight Capacities
    Roller bunk brackets like the CE Smith Bolster and Swivel Mounting Brackets for Bunk Boards # CE10196G-4 do not have listed capacities. I spoke to my contact at CE Smith and he informed that that as long as you are under the capacity for your trailer and the roller bunks that are being attached to the brackets the brackets will be fine.

  • Brake Winch Recommendation for Trailer with Roller Bunks to Feed Boat Out Onto Water
    Your best option would be a winch that can be fed out when you are launching your boat so that you don't have to just let it free wheel and take off in to the water by itself. For that the Fulton hand winch part # F142430 that has a hand brake would be a fantastic option. It would let you feed the winch out as needed in a controlled manner and won't require you to swap out the rollers of your trailer for bunks. For a cable you'd then want the part # FWC7500100.

  • How to Select Bunk Boards for a Pontoon Boat Trailer
    The correct size of bunk boards for your pontoon boat trailer is going to vary depending on configuration. Generally speaking, you will want the horizontal bunk boards to reach from the transom edge to the hull. Most people will then run two sets of vertical bunk boards like CE Smith Bunk Style Guide-Ons part # CE27671 in the middle of the trailer to center the boat and then two sets of horizontal bunk boards on each side to support the pontoons. The longest horizontal bunk boards we offer...

  • Recommended Bunk Boards For Boat Trailer To Support 16-Ft Deep V Boat
    The weight of the boat on your trailer should be shared by the keel rollers and the bunks. All of the weight should not be placed on either the rollers or the bunks. It sounds like you have bunks that are just too short for your boat size. I recommend adding additional bunks like part # CE27800 to your trailer so all of the weight does not fall on the keel rollers. To support the bunks I also recommend the bracket assemblies like part # CE10196G-4.

  • Tallest Bunk Bolster Brackets to Clear Trailer Tires on a Boat Trailer
    Your best option is going to be bolster bracket set # CE10196G-4 which is a quantity of 4 so if you wanted 6 you would need 2 sets and you would have a couple of spares should they be needed. These are 16-1/4 inches long with some adjustability due to the slotted holes. For u-bolts use # CE15283GA-8 (which is a set of 8 because each needs 2 u-bolts).

  • Recommended Bunk Brackets for Zodiac Inflatable Pontoon Boat Trailer
    The CE Smith Bolster Bracket # CE10052-32G features a span of just barely over 15 inches so it might be a bit small to comfortably support the 16 inch tubes on your Zodiac Inflatable Boat. You will likely be better off using a set of standard brackets like the CE Smith # CE10196G-4 that feature a swiveling design to let you tilt the bunk boards at an angle for the pontoon. For the bunk boards themselves you can use the CE Smith Carpeted Boards that are available in lengths of 7 feet...
