Rust-resistant assemblies let you install 2 bunk boards on your boat trailer. Swivel brackets enable bunks to tilt when loading a boat. Mounting slots allow for height adjustment. Dimpled surfaces keep brackets from sliding along the trailer frame.
Features:
Specs:
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.

Excellent product, exactly what I was looking for. Thank you for sending it so quickly. Will definitely do more business with etrailer.com
The only thing I would change would be the slots. They need to be a full 4" so a 4"u bolt can fit through it. Otherwise great on time shipping
Super service, fast shipping, excellent product. Will definitely be my go to place for quality trailer parts.
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.
I am hoping it will work on my trailer. All the parts are as you described. The ordering was easy and shipping was fast. Thank you
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.
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.
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!! :)
Heavy duty used to convert a roller trailer to bunks. Shipped promptly. Would buy from this merchant again and again.
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.
Everything worked out fine. They were easy to install.
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.
Nothing special here just an average order with normal shipping time
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.
Saviors are the folks at etailer.com. 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.
great product fast shipping
Those brackets look to be just what I needed. I’m installing new bunks and brackets on my boat lift, and wanted a proper bracket for our Boston Whaler 130, so I’m duplicating the angle and length of our trailer on the boat lift. I found the correct dimension UBolts, and those fit the bracket slots exactly right.
Excellent!
Worked great in converting a pontoon lift to a boat lift for my sons 18 ft fishing boat
These brackets were very lightweight, but adequate enough to get by. Would search out a thicker metal next time.
I received the proper u-bolts as ordered. However, the four 13" swivel bracket assy ordered were instead four 8" swivel bracket assy. I paid extra for expedited shipping so to finish the project by this week-in. Had to re-order and return incorrect items. Won't be able to finish the project as promised until late next week. Realizing the item/part numbers were close, common sense should enable one to identify a five inch differential in two like items, by 39%. Aside this problem, etrailer has excellent items and would definitely purchase 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.
Great product that I received and fitted today
As usual, etrailer has come through with a quality product and quick
delivery.. worked perfectly..
Very easy to install. Fully adjustable up/down and tilt side to side by several degrees. Great product with high grade hardware. It took only 45 minutes to install this outboard pair of bunks. I will buy from etrailer again!!

After a few launchingsrecoverys and several months of a heavy boat sitting on the trailer , the hardware hasn’t moved at all. Very stout. Great product.
