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.

These are prefect for the size of my trailer to hold on the new bunk brackets
Measure your trailer carefully, a couple of times. These made installation so easy.
Check out the weight of your boat.

Received my order quickly and all the items worked as promised, which is not always the case when ordering from the internet.

Very satisfied with the brackets I bought. Great price, great quality, and quick shipping! No issues at all in 1 year, and after a summer of boating, and a full season of duck hunting in freezing weather, they still look brand new!

As always, all ordered items arrived in a timely manner and were all exactly as advertised. Several are already in service on my boat trailer.

  • 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 you...

What you need is the CE Smith U-Bolts - Galvanized - 3-13/16" Long x 3-1/16" Wide x 1/2" Diameter # CE15283GA. These U-bolts are the right size for your frame with a 3-1/16" width.

  • 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...

  • Torque for Installing Nuts of U-Bolt Kit # CE15283GA-8
    The correct torque spec for trailer suspension u-bolts will depend on the the diameter of the bolt. You will want to use the following depending on bolt size: 1/2" bolts: 45 ft/lbs - 70 ft/lbs 9/16" bolts: 65 ft/lbs - 95 ft/lbs 5/8" bolts: 100 ft/lbs - 120 ft/lbs 3/4" bolts: 140 ft/lbs - 160 ft/lbs Since the # CE15283GA-8 is a 1/2 inch diameter you'd want to go with 45-70 and you'd be good.

  • Is Mounting Hardware Included with CE Smith Bolster and Swivel Bracket Assemblies, # CE10000G-4
    The CE Smith Bolster and Swivel Bracket Assemblies, # CE10000G-4, do not come with any mounting hardware. Because the brackets can be used for different size and type bunks they do not include the hardware because it would not cover all applications. The holes that attach the bunk board to the swivel bracket are 3/8 inches in diameter. To attach the brackets to the trailer frame you can use U-bolts such as # CE15283GA-2 which are 3-13/16 inches long, 3-1/16 inches wide, and have a 1/2...

  • Availability of 7 Feet Long 2 x 4 Carpeted Bunk Boards for a Boat Trailer
    The longest carpeted bunk boards we currently offer is 6 feet in length. It's the CE Smith part # CE27840 and each 6-foot long 2x4 is covered in marine grade carpet. You can easily construct some bunks yourself. Go to your local lumberyard and get some yellow pine 2x4x10 boards. You can then purchase some of the marine-grade carpet we offer, like part # CE11372. You'll need one roll per bunk, which means you'll have some scrap left over, which you can utilize as needed for other projects....

  • Can I Weld the CE Smith CE10160GA-2 Heavy Duty, Vertical Bunk Brackets
    Because the CE SMith Heavy Duty, Vertical Bunk Brackets # CE10160GA-2 are galvanized steel, I don't recommend welding them because of the inherent issues that come along with welding on a coated steel. These are designed to be secured to the trailer frame using U-bolts like the # CE15283GA-2, so I do recommend using that method. I've gone ahead and linked our entire selection of u-bolts in case you find that you need something a bit longer, as well.

  • What are Benefits of Bracket Assemblies on Boat Trailer?
    Even if the boards can bear the weight of the boat, by concentrating the weight on a smaller, 3 inch surface, there is a greater risk to denting or deforming the hull of your boat compared to having the boat's weight spread out over a larger surface. To install your bunk boards, the assemblies you mentioned, the Bolster and Swivel Bracket Assemblies # CE10190GA-4 are the best overall option. They attach with a pair of U-bolts # CE15283GA-8 each for connection security, and both the brackets...

  • How Do CE Smith Heavy Duty, Vertical Bunk Brackets CE26233-34GA Get Installed?
    You are correct. You will want to mount the longer 95 degree bracket of the CE Smith Heavy Duty, Vertical Bunk Brackets - 85 and 95 Degree Set # CE26233-34GA on the lower section of the angled crossmember on your boat trailer, and the 85 degree bracket on the higher section of the crossmember. In addition you will need 1/2" diameter U-bolts to secure the brackets to the crossmember. If your crossmember is 3" x 3" then I recommend the CE Smith U-Bolts - Galvanized - 3-13/16" Long x 3-1/16"...

  • Will CE Smith Double U-Bolt Bolster and Swivel Bracket Assemblies - 10-1/4" Work on a 3,500 Lb Boat
    The CE Smith Bolster and Swivel Bracket Assemblies part # CE10191GA-4 do not have a specified weight capacity as it can vary by the strength of the u-bolts used in conjunctions with these brackets as well as how many brackets are used per board. I know this is frustrating to not have a specific weight capacity but unfortunately the manufacturer just does not provide this. If you feel you'll be exceeding the limits of the swivel brackets, you can always double up using multiple sets per...

  • Recommended Replacement Bunk Brackets for Escort Bunk Trailer
    I have a solution for you, but we don't have any of the bunk brackets that are exactly the same as the ones you're replacing. Instead, you can use the CE Smith # CE10000G you were looking at to replace the bunk brackets on your current trailer. These are swiveling brackets, so the angle of the bunk boards will be able to be adjusted to match your current setup. In order to mount these bunk brackets you'll want to use U-Bolts like the CE Smith U-Bolt - Galvanized - 3-13/16" Long x 3-1/16"...
