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.

Worked great in converting a pontoon lift to a boat lift for my sons 18 ft fishing boat


Heavy duty used to convert a roller trailer to bunks. Shipped promptly. Would buy from this merchant again and again.


Converted a late 80's EZ-Loader roller to a bunk construction for my Boston Whaler 18 Outrage. Great product and easy to use. Quality construction and perfect fit. Purchase the recommended extra washers for the U bolts, worth it.


Nothing special here just an average order with normal shipping time

Bob - 07/12/2022


They worked great.


Very quick thanks.


EXCEPTIONAL service, products and FAST delivery! etrailer is my “GO TO” supplier for all my trailer needs!!


Well built product. I’ll take some photos when I get these brackets installed!


as in the past the package arrived in record time and as advertised


These are solid swivel bracket assemblies however I'm still struggling as to how I am going to install them and if I need additional parts. I give the site a below average score however the products are well made.


Saviors are the folks at Converting rollers to bunks was simple. Rook off all the rollers, measured up the trailer and boat, went to etrailer to shop for ALL the parts to make the conversion. Placed order, for all my needs, got over the $99 shipping hurdle and three days later, got to working on the actual conversion. Within a few hours, my EZ-Loader that my Whaler sits on, was now on brand new bunks, resting comfortably.


These brackets replaced the old rusty bunk brackets on my salt water trailer.
Measure the height of the bunks on your trailer now and order ones that will be tall enough. They are adjustable by the slots you can see in the bracket. VERY EASY to install with the U bolts. The tops swivel easily so you can tilt the bunks the way they need to be to fit your boat properly.I have never worked on a trailer before, this was a first and it was easy. Check out the videos and photos provided. OUTSTANDING COMPANY with outstanding products.


I ordered these boat trailer bunk brackets to modify a trailer I bought to fit the boat I have. The brackets were just right for what I needed and of good quality and durable. I received them in a timely matter, about 4 days with the regular shipping method. I will definitely order from Etrailer again for my trailer needs.


The trailer brackets have performed well for over one year. They are quite durable and the galvanized coating ensures that they don’t rust even in salt water. They fit right in on my EZ Loader trailer.


So far, the product has been excellent. Haven't had a chance to use the unit in the water yet, but am working on building my boat for the trailer. It was nice to hace a service person help me find what I was looking for on your web site. Give me another month, and I can send pics of the newly installed parts. Thanks.


Really flimsy brackets. One broke off, causing bunks to fail, breaking other brackets and causing $$$$ in damage to my boat hull. Its not a heavy boat either (about 2,500 lbs, 19ft boat). Do not buy these if you like your boat and don't want to repair your hull. Maybe these can work for a jet ski or something, not a boat.


Haven't actually tried the bunks and guide boards I bought because it is winter here now but the service and selection were awesome. They had everything I was looking for in one place and the delivery was right on time. The instruction videos and pictures were very helpful. Highly recommend etrailer for all your trailering needs and more.


I so wish I had discovered etrailer earlier! The same product was $30 more expensive at other places and shipping was very prompt! Additionally, Heidi M. was an absolute joy to work with! She was friendly and truly interested in helping me find what I needed. She is definitely my go-to person whenever I need trailer parts from now on! Thanks, Heidi!! :)


Excellent product, exactly what I was looking for. Thank you for sending it so quickly. Will definitely do more business with


Products came exactly as advertised in a extremely timely manner.


The shipping was great, fast, the order was as described. Highly recommend


So far so good. Brackets have held up well this past year and hope they last a long time.


Great products. Great service. Great company


They are great, well made and easy to work with and the hardware is of quality and heavy gauged. Good job. Dwight


Brackets were exactly what I needed at a good price and they arrived as scheduled.

  • Can 6 of the CE Smith Bolster Brackets CE10002G-4 be Ordered
    You would just need to order a quantity of 6 of the part # CE10002G to get six of the brackets that come with the part # CE10002G-4.

  • Appropriate Replacement Bolster Brackets for Trailer Carrying 3000-lb Boat/Motor
    We offer bolster brackets both singly and in sets of four and in a range of sizes and types for both bunks and rollers. The link provided will let you see all available parts. You can use the filters at the left-hand side of the page to select parts by type and size. Extra capacity in any system is never a bad idea but these components are not weight-rated so as long as you find a suitable size and type you should be fine.

  • Can Boat Swivel Bunks Be Tightened So they Won't Move
    The nuts that hold the swivel to the brackets like on the # CE10002G-4 can be torqued down to prevent movement if desired.

  • Do CE Smith Bolster and Swivel Bracket Assemblies # CE10002G-4 Have Weight Capacity
    Roller bunk brackets like the CE Smith Bolster and Swivel Mounting Brackets # CE10002G-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. For your 2,000 lb boat the # CE10002G-4 would easily have the needed capacity.

  • Would Bunk Brackets # CE10002G-4 Have Capacity for 2,060 lb Boat

  • How High Will CE Smith 13 Inch Bolster Bracket Sit Above 3 Inch Crossmember
    The # CE10002G-4 CE Smith Bolster and Swivel is 13" tall. Assuming you mount it at the position to gain the most height, you should have 9" remaining. Losing the height from attaching to the 3" crossmember leaves you with 10" remaining. You will lose 1" at the bottom with the 1/2" below the lower mounting hole and 1/2" diameter U-bolt. Accounting for the added height of the bunks, you should be sitting over 11" once installed. I have attached a video review of the bracket for your reference.

  • Bolster Brackets for Bunks on a Boat Trailer
    Considering that there will be a bunk of some kind mounting on top of the brackets once installed the 11 inch overall height of the CE Smith Bolster and Swivel Mounting Brackets # CE10001G-4 should work just fine for you. If you determine the 11 inches is not enough we do have a set of four 13 inch brackets, # CE10002G-4. The slotted holes on these brackets will allow for some adjustability.

  • How Many Bolster And Swivel Brackets Are Needed For A Boat Trailer
    I spoke with my contact at CE Smith, and they said the Bolster and Swivel Bracket Assembly for Boat Trailers, like part # CE10000G, do not bear the weight of the boat. 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. If you are buying several brackets, I would recommend part # CE10000G-4. This is a set of 4 of the 9 inch adjustable brackets. If you need longer adjustable...

  • Determining Length of Bolster Bracket for New Bunk System on Boat Trailer
    To be on the safe size, I recommend going with a 13 inch bracket # CE10002G-4 at the back of the trailer and an 11 inch bracket with # CE10003G at the front. A nice feature on these brackets is that they will each actually have as much as 3-3/4 inches of height adjustment due to their mounting slots, so even if its total height is a bit higher than needed, you can adjust them down. This will allow you to have the perfect height for your new bunk support system. I have attached a short...

  • Does the CE Smith Swivel Bracket Come with a Bolster Bracket
    The swivel bracket # CE10200G is just the L-shaped bracket. it can attach to a bolster bracket. To get the bolster bracket with the swivel already on it you can use one of the following: # CE10000G, 9 inches tall # CE10001G, 11 inches tall # CE10002G, 13 inches tall There are also sets of 4: # CE10000G-4 # CE10001G-4 # CE10002G-4 I have also included a link to the bolster brackets we carry with and without swivel brackets attached.

  • Determining Trailer Bunk Board Length for 14 Foot Sailboat
    It's not an exact science but typically you want the bunk boards on a trailer to extend all the way to the rear of the boat. It wouldn't hurt to have them go a bit beyond this too to ensure proper support during travel. Since the front of the boat should be supported by the bow stop you usually see bunk boards that measure about half the length of the boat itself. Since you no longer have the boards that originally came on your trailer it might also be a good idea to try and contact the...

  • Recommended Bunk Board Brackets
    We definitely have options for brackets to mount your bunk boards. This will depend on the size needed, of course, but here are a couple options for you to take a look at. The CE Smith # CE10003G-4 will come as a 4 pack and are 11 inches tall, including the swivel bracket on the top. If you need a little more height, the # CE10002G-4 will be much the same, but measure 13 inches. The swivel bracket on the top pf these will let you angle your bunk boards to the angle that suits your needs best.

  • Dimensions of the CE Smith Carpeted Bunk Boards # CE27810 and Availability of Swivel Brackets
    The CE Smith Carpeted Bunk Boards # CE27810 that you referenced do measure 48" long x 1-3/4" wide x 3-3/4" tall. There are swivel brackets available for adjustable height. For an overall height of 9" you will want part # CE10000G-4, for an overall height of 11" part # CE10001G-4, and for 13" part # CE10002G-4. I have attached a review video of the bunk boards being installed for you to check out.

  • Bolster Brackets and Swivel Assemblies for SeaDoo Trailer
    I can help you find the correct bolster and swivel brackets for your Seadoo trailer. The CE Smith part # CE10002G is a galvanized 13 inch bolster with a swivel bracket assembly. The swivel bracket will fit your 2 x 4 bunk great, but the brackets included have a 2-1/2 inch center spacing. We do offer a swivel bracket with a 2 inch center spacing # CE10206AA, but with either I would recommend drilling a hole in the bracket where you need it. It's important to keep in mind that its a...

  • Will Galvanized Steel Bolster Brackets # CE10192GA-4 from CE Smith Hold Up in Salt Water Conditions
    All of the boat trailer bolster brackets that we offer, such as # CE10002G-4 and the set you referenced # CE10192GA-4, are made of galvanized steel. This zinc coating helps resists salt water corrosion in such environments. These brackets do not carry a specific salt-spray rating but they can be kept in best shape with a regular fresh-water rinse (as will your boat, of course) to remove the salt and help reduce corrosive effects.

  • Brackets for Adding Additional Bunk Boards to Magic Tilt Galvanized Kayak Trailer
    The problem is that your bunks need to face a different direction than what standard boat trailers have so it's hard to have a solution since your setup is unique. That said I don't see why you couldn't use CE Smith Bolster and Swivel Bracket Assemblies # CE10002G-4 attached to the rails front to back on your trailer so that could could mount the bunks. For a U-bolt kit you could then use the part # CE15283GA-4 to secure the brackets.

  • Can Top of CE Smith Swivel Bracket be Tightened to Keep Them at Angle
    The top of the swivel bracket is not something that can be tightened to completely stop the swivel for the CE Smith Bolster and Swivel Bracket Assemblies # CE10002G-4. So there is always going to be some swivel in these brackets to ensure that they are always at the correct angle when being loaded. I also wanted to mention that to install these brackets you will need U-bolts, the CE Smith U-Bolts # CE15283GA-4. I have added some links below to video reviews for you to check out as well...

  • What is the Difference Between a Bolster Bracket and a Bunk Bracket
    The terms bolster bracket and bunk bracket refer to the same thing. For example, CE Smith part # CE10002G-4 is a bracket that can be used on a boat trailer to mount either a standard carpeted wooden bunk board (that supports the boat's hull) or a roller bunk like # DL21741.

  • 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).
