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

Steel parts are galvanized by being hot-dipped in zinc after they have been 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.

These worked perfectly on my gheenoe trailer.

Well made brackets !

by: Thomas 06/11/2020

So far so good. The brackets are working fine so far. Haven't put the trailer on the road yet, but the boat requires bunkers to have a curve or bow in them. The middle brackets stand the torsion as well as the weight of the boat. Easy to install as well.

Heavy duty, easy to install, the best customer service ever! Thank you for the videos and the detailed information. Thanks.

by: Peder S 04/21/2014

First off, I want to say that the products that I ordered from etrailer.com were of high quality and were easy to install, and lets not forget about the fast shipping and my favorite - the personal touch added to the email communications where each one is signed by a human (rather than something generic).

My project itself entailed replacing the two (original) vertical mount 4' bunks on my boat trailer (see the attached pictures). These were set-up to hold a 15' sailboat. I recently purchased a 12' (plastic) jon boat, and I felt that the jon boat needed better support on the trailer so that it didn't warp or dent.

After doing a lot of research, I decided to go with two horizontal mount 6' bunks. They were pre-finished at a cost less than if I were to purchase the individual components (wood, glue, carpet, staples, etc.) and do the assembly work myself. Attaching the hardware and mounting them to the trailer was a snap - see the attached pictures for the finished setup.

They work awesome, I'm actually going to order 2 more , I should have ordered 6 instead of 4 . Also great communication with them.

by: DJ 07/26/2019

These are actually for wood bunks, not the roller bunks which I bought. Had to drill another centered hole in top. Not hard though.

I took my existing utility trailer that I bought at the local supply store and converted it to a boat trailer for my new RIB for a couple hundred dollars. It saved me well over a thousand dollars and works great.

Didnt work for my application. Was suggested as an alternate to longer version that was back ordered but wound up being significantly different mounting styles (holes). Had to reorder another bracket and customer service is being slinky about it's status (could be backordered as well) even though I've been charged $450 already. Cart did not indicate items were delayed. Somethings fishy.

I'm not a trailer person but I found "etrailer's" website informative enough to know what I needed. I also had the benefit of an etrailer staff member who knew his products and thus able to make sure I bought the correct pieces. The plus was when the items arrived much sooner than the shipping time they quoted. I have not yet installed the items but hope to do it this week. Excellent source to buy quality trailer parts.

It was nice to purchase the whole set instead of individually.

by: Bill 07/26/2018

this has happened again. I can't rate a product that should last years the minute it gets in my hand. The pieces LOOK good. The shipping was timely and the price was fair none of which tells me or you how good the product IS. Get back after two years of dunking in fresh and salt water and I'll give an honest review.

so far so good. After a year of dunking in fresh and salt water there is no sign of rust and no cracks in the material. Im pleased and a little surprised they held up so far given the poor quality of a lot of galvanized pieces nowadays. If they hold up this good after two years they have my wholehearted endorsement, for what thats worth.

Do you have a question about this Boat Trailer Part?

Should Lock Washers or Nylon Lock Nuts be Used for CE Smith Bolster and Swivel Bracket
Hey Dave, I think you figured out your problem without realizing it - you need to have either lock washers or nylon lock nut in order to secure the CE Smith Bolster and Swivel Bracket Assemblies # CE10000G-4 to your trailer frame. Without hardware that "locks" in place, the weight of your boat will slowly cause everything to start slipping the more you use it. We don't have a specific torque spec for the hardware, but if you try using the correct hardware for it, I'm confident you'll...

Recommended Roller Bunks Replacement for Wooden Bunks for G3 1860 Boat
We do have a variety of roller bunks that can be used as a direct replacement for carpeted bunks. I recommend either going with the 2,500 lb capacity which comes in Black # DL21754 or Silver # DL21740, OR the 3,000 lb capacity which also comes in Black # DL21755 or Silver # DL21741. I have also attached a link to all of the options that you can check out, as well as a link to all of our brackets if they also need replacing.

Can Bunk Boards Longer Than 69-1/2" be Installed on a Boat Trailer
Hey Dave, thanks for reaching out again!

Basically, as long as it fits on your trailer and all of the weight ratings are being observed you'll be good to go.

Availability of 10' Long Carpeted Bunk Boards
Hey Verne! I do have a solution but, 10' bunk boards are not something that we carry.

You will also need the CE Smith Bolster and Swivel Bracket Assemblies # CE10000G-4. If you need anything else don't hesitate to reach out in the comments below.

Parts Needed to Convert a Boat Trailer From Rollers to Bunk Boards
This can absolutely be done. While there are not "kits" for doing the conversion, we do have the parts that you will need. These are not kitted together because each boat/trailer combination is different, so it is easier to not kit them. It is recommended to have bunk boards that are at least 50% of the length of your boat. You can have longer boards if you would like, but you want at minimum 50% of the length. Since your boat is 21', you will want bunks that are at least 10.5' long. I...

How Many Support Brackets Are Needed For A 14 Foot Bunk Board Carrying A Pontoon Boat?
As the bunks will be support the weight of your pontoon boat, I always recommend getting them to the end of the transom, or as close as possible. As you mentioned using 14 foot long boards, you will want at least 4 evenly spaced support brackets per board, but 5 is better. You have a few options for these brackets as well. I tend to like the CE Smith V-Wing Bolster Bracket # CE26244G as I prefer the rigid style and it can hold two boards. However, our most popular style is the CE Smith...

The U-bolt that attaches the brackets to the trailer frame support the weight of the boat. There should be a bracket attached to each cross member of the trailer frame.

How To Convert a Boat Trailer from Center Rollers to Bunk Rollers
Yes, it is possible to switch from center rollers to bunk rollers on a boat trailer. For this, you will first need to remove the center rollers and then you can install a set of bunk rollers, part # CE27710 along with part # CE10000G-4 to support the hull. Then, in order to support both the port and starboard sides you can use part # CE27600. I have attached a photo of a similar setup with bunk boards instead of bunk rollers for the hull.

Recommendation For Adding Bunks or Rollers to a Calkins Boat Trailer for a 21' Boat
As far as size is concerned, you want the bunks/rollers to be at least half the length of your boat. Whether bunks or rollers are the better option really comes down to your use. If you take your boat on and off of the trailer quite a bit, then going with rollers would be a good choice. The boat will smoothly roll over the bunks which is easier and less taxing on the hull of the boat.

Should Boat Rest on Bunk Boards or Keel Rollers on Boat Trailer

However, they should not hold the majority of the weight of your boat on the trailer. In addition to keel rollers you will also want to use bunk boards like the # CE27840...
