One Piece Bracket for 12" Roller for Boat Trailers - 408300

Average Customer Rating:  4.9 out of 5 stars   (15 Customer Reviews)


I've bought a tow hitch and parts for a boat trailer I was building. These guys have the best service, the cheapest price, and the highest quality parts. I would rather wait the couple days it takes to get my order and have it right than to have to scurry from store to store dealing with some sales person that has a whole 8 hours training (maybe) trying to find what you need. Anyway, etrailer solves that problem. Thanks


When they arrived I was surprised at how thick they were. These won't wear out any time soon. Great company, lots of follow up emails, etc.. I ordered rollers from another company in florida, when I called them because the order was wrong, no one spoke english. Instead of sending back the wrong ones (shipping would cost more) the first place I went was e trailer to order more rollers, because I now feel safe and believe that this company will get it right. Thanks e trailer for making my day a lot better.


I bought this Product for a Truck Canopy Rack.
Works great, shipped quickly Thanks


I recently ordered and installed roller boat guides awsome product - simple install. Worked out very well!


I have purchased several items from etrailer and all I can say is wow! Fast delivery, great packaging and you get excellent quality at a more than fair price. You can't go wrong with this company. Top Notch


Excellent products and service.

if the 5/8" shaft were made of stainless steel it would be a super-excellent product.


Very fast delivery and top quality product. I will be shopping here again!!


Awesome support while ordering the parts. Everything fit perfectly. Shipping was very fast.

Everything is working fine.

  • Securing Keel and Bow Rollers to a Bracket on a Boat Trailer
    When installing rubber rollers like a keel or bow roller there are a couple of parts in addition to the roller you usually need. First, the roller needs to mount to a bracket of some kind. For example, if you are using a 5/8 inch steel shaft you could use the One Piece Bracket, # 408300. The bracket bolts to the trailer, the shaft goes through the compatible roller and bracket and it is held on the bracket using 2 Pal Nuts (Qty 1), # CE10801. Like any part, over time, the pal nuts may...

  • What is the Exact Length of the 12 Inch Yates Side Guide Roller # YR12243-5
    I went out to the warehouse and measured a few of the Yates Side Guide Rollers # YR12243-5. They were 11-7/8 inches long so they will work great for a 12 inch bracket such as # 408300. Both the roller and bracket take a 5/8 inch diameter shaft such as # CE10727A.

  • Recommended Bracket and Roller Shaft For Yates Side Guide Roller 12 Inches Long
    The Yates Side Guide Roller for Boat Trailers - Heavy-Duty Rubber - 12" Long - 1/2" Shaft # YR12243-4P is compatible with the CE Smith Side Angle Mounting Brackets for Boat Trailer Rollers - Galvanized Steel - 1 Pair # CE10211G.

  • Parts Needed to Replace 12 x 2-1/2 Inch Rollers on Boat Trailer
    You may be able to use the 12-3/4" x 1/2" Roller Shaft with Pal Nuts # CE10705A with the Yates Side Guide Roller 12" Long - 1/2" Shaft # YR12243-4P, but it won't give you much space to work with. A better option is to use the Yates Side Guide Roller 12" Long # YR12243-5 instead, which uses a 5/8" shaft, along with bracket # 408300, shaft and pal nuts # CE10727A. We don't carry a 1/2" shaft kit that is longer than 12-3/4". The CE Smith U-Bolt Kit # CE15283GA-4, that you were looking at,...
