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.

Video Transcript for CE Smith Boat Trailer Parts - Roller and Bunk Parts - CE15283GA Review

Today we're going to be taking a look at the C.E. Smith U-Bolt. This is a heavy-duty square U-Bolt that lets you secure a bracket to your boat trailer. This is designed for use with a bolster or a bunk board bracket that has 1/2" diameter mounting holes or 1/2" wide mounting slots. The unit's constructed of galvanized steel so it's going to do a great job at resisting rust and corrosion. It is suitable for saltwater exposure.

It does come with the mounting hardware, so you're going to get two split lock washers and two nuts. The product is made in the USA. With this part number you're going to get one kit, so one bolt, two split lock washers, and two nuts. A few measurements to go over with you real quick. Starting with the inner width, that's measured from inside edge to inside edge. That's going to give us an inner width measurement of 3-1/16".

The length measurement is measured from this portion right here, so inside edge to the end of the threaded portion. That's going to give us a measurement of 3-13/16". The unit has a diameter of 1/2". The thread length, that's going to give us a measurement of around 1-1/2" long, just the threaded portion. The overall length from the very top to the end of the threads, that's going to give us a measurement of about 4-5/16" long. That's going to do it for today's look at the C.E.

Smith U-Bolt.

Ask the Experts about this CE Smith Boat Trailer Parts
Do you have a question about this Boat Trailer Part?


  • Recommended Bunk Brackets For Pontoon Boat Trailer
  • If there is no flex in the bunks with the pontoon boat loaded, you should be fine with the 1/2 inch clearance. If you are possibly hitting the frame of the trailer when traveling I recommend replacing the bunk brackets with taller ones like part # CE10161GA. This bracket sits on top of the frame of the trailer and are 8 inches tall, and 5 inches wide with 4 mounting holes that are spaced 1-1/2 inches apart center to center. This will give you options to mount the bunks at the height...

  • Can CE Smith Fender Be Mounted Without Drilling Into Boat Trailer Frame?
  • The CE Smith Single Axle Trailer Fender w/ Top and Side Steps - Black Plastic - 14" Wheels - Qty 1 # CE19504 can be installed with a u-bolt around your trailer frame instead of drilling into the frame using CE Smith U-Bolt - Galvanized - 3-13/16" Long x 3-1/16" Wide x 1/2" Diameter - Qty 1 # CE15283GA. This will require specific placement of the fender and wheel clearance for the flat side of the u-bolt, but it is possible to mount the fender in that way on your boat trailer. The strength...

  • 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...

  • Recommended Roller Bunks For Pontoon Boat Trailer And Shallow Water
  • A couple sets of the Dutton-Lainson Boat Trailer Deluxe Roller Bunk - 5' Long Sections - 12 Sets of 3 Rollers # DL21741 will drastically help with getting your pontoon boat on and off the trailer smoothly and easily as there isn't any friction compared to bunk boards. This will make it easy to get the back of your pontoon in the water while supporting the weight. You will want to make sure that you keep your winch connected and back it down if you have a large drop because the boat will...

  • Recommended Roller Bunks For Tracker Deep V Boat
  • You can use roller bunks like the Dutton-Lainson Boat Trailer Deluxe Roller Bunk - 5' Long Sections - 12 Sets of 3 Rollers # DL21741 instead of carpeted bunks on your 2012 Deep V Tracker boat without any marks or indentations. The roller bunks provide support as well as the ease of loading and unloading. The support will not be so focused on a single location as to leave an indent or mark. I've attached a photo to give you some dimensions. You may also want the Boat Trailer Roller...

  • 3 inch Wide U-Bolt Recommendation for Bunker Bracket
  • The closest thing we have to what you are looking for would be the part # CE15283GA that has an inner width of 3-1/16 inches. The length of the U-bolt is 3-13/16 inches. The width of the U-bolt is the distance between the two posts of the bolt.

  • Mounting the Dutton-Lainson Boat Trailer Deluxe Roller Bunk on Boat Trailer
  • The Dutton-Lainson Boat Trailer Deluxe Roller Bunk # DL21741 is designed to attach directly to 2 x 4 bunk boards so it will may work for your set-up, but I recommend instead to mount the roller bunks with the Roller Bunk Bracket # DL21742 and U-Bolts # CE15283GA. This will give you roller bunks that are certain to work; you can see the simplicity of how this set up will work in the accompanying photo. I've also attached links to video reviews of these parts for you to take a look at.

  • What Diameter U-Bolts Will Work With CE Smith Bolster and Swivel Bracket Assembly
  • I attached a photo of the CE Smith Bolster and Swivel Bracket, part # CE10000G you can check out. As noted on the photo, the slotted holes on the bolster are 2-3/4 inches long and 1/2 inch wide. There is a distance of 1/2 inch between the slotted holes. U-bolts like part # CE15283GA are recommended for the bracket. These U-bolts measure 3-13/16 inches long, 301/16 inches between the u-bolt legs and are 1/2 inch diameter.

  • Recommended Roller Bunks For Tri-hull of Restored 1974 AMF Crestliner Muskee
  • Thank you for your service. For your 1974 AMF Crestliner Muskie, from what I can find online is a nice boat that will work really well with roller bunks on the trailer. I recommend the Dutton-Lainson Boat Trailer Deluxe Roller Bunk - 5' Long Sections - 12 Sets of 3 Rollers # DL21741 you mentioned. This will allow you to launch easily. You will want to make sure you have a rope to hold onto your boat as I've heard of people being ill prepared for such an easy launch compared to bunk...

  • How Long of a Bunk Roller to Use on a Boat Trailer
  • There is not really a rule for the length of roller bunk needed but a good way to select this would be to match them to the length of your bunk boards. Therefore, you would want to use two sets of the Boat Trailer Deluxe Roller Bunk part # DL21740. These bunk rollers have a 2,500 lb weight capacity. If you need more than you would need to go up a size to the Boat Trailer Deluxe Roller Bunk part # DL21741 which are 5' long and have a 3,000 lb weight capacity. Don't forget the brackets...
