Video Transcript for CE Smith Panel Bracket for 5" Boat Trailer Rollers: The Breakdown

Today on our Jon boat trailer, we are going to be installing the C.E. Smith bracket for boat trailer rollers out of galvanized steel, part number CE10301G. In addition to the bracket, we are also going to be installing a Yates Keel roller for boat trailers, part number YR5244-105EC. Here is the bracket that we are going to be installing here on our boat trailer. We are going to be installing it here on this cross member and on our particular trailer, there is already actually a couple of holes already drilled in the trailer that line up with these adjustment slots here. It does have the 5/8" hole drilled in the upper part of the bracket that allows for a roller such as one like this. Slide it into place and you will need to supply your own hardware to attach the bracket to your boat trailer, as well as to attach the roller to the bracket. I will go ahead and pick our bracket here. Go ahead and line it up.

On the back side here we are going to put a washer and a nut. Go ahead and do that for the other hole as well so we can kind of keep the bracket up. Next, we are going to need to install the roller here. To install the roller to our bracket, we are going to be using a 5/8" bolt, couple of 5/8" flat washers, 5/8" lock washer and a 5/8" hex nut. Go ahead and put a washer on the bolt first and then go ahead and get our roller into the bracket. Now that we have our roller lined up, we will go ahead and slide our bolt through the bracket and the roller. We will then put another flat washer, slide our lock washer and finally the hex nut into place.

Go ahead and tighten down the roller and make sure that it is still able to be moved. Go ahead and slide it up so we are touching the bottom of the boat. Now that we have the bracket and the roller in the proper position, we will go ahead and tighten everything down. This right here is just one example of how you can use this panel bracket from C.E. Smith. Depending on your exact application, you may need to use more of a U-bolt style to attach it to your trailer. C.E.

Smith does sell these and that is part number CE15252A for a three inch long version, or for a four inch long U-bolt, it is part number CE15253A. Depending on your trailer will depend on exactly how you mount it. With that, that will conclude our installation of the C.E. Smith panel bracket for boat trailer rollers made out of galvanized steel, part number CE10301G on our Jon boat trailer.

  • Choosing a Replacement U-Bolt for a Boat Trailer
    Hey Dave, it's great to hear from you again! The CE Smith U-Bolt - Zinc-Plated Steel - 3" Long x 3-1/8" Wide x 7/16" Diameter # CE15252A you were looking at could work for if the dimensions match what you currently have. You won't get any galvanic corrosion by mixing those materials - it really only happens with aluminum. If you can let me know the dimensions of your current U-Bolts I can see if we have something that's the same for you.

  • Recommended Roller Bunks for 2020 18 Express Boat with Back Track Aluminum Trailer
    The best option in my opinion is to use the Dutton-Lainson Boat Trailer Deluxe Roller Bunk - 5' Long Sections - 12 Sets of 3 Rollers # DL21741 which will allow you to angle the set farther up the trailer to help you center the hull but I recommend using a keel roller like the CE Smith Deep V Keel Roller Assembly for Boat Trailers - Galvanized Steel/Black Rubber - 5" # CE10401G to help center the boat.

  • What Are The Inside Dimensions Of The Buyers Products Utility Storage Box 3371712240?
    You are correct, 44" x 19" x 17-1/4" is regarding the exterior of the Buyers Products Utility Storage Box - Black - # 3371712240 which also includes the lid. For the usable interior dimensions you are looking at about 41" long, 18-1/2" wide, and 15-1/2" deep. I attached a demonstration video for you to check out which shows these dimensions.

  • Recommended U-Bolt to Fasten Bolster Bracket to 3 x 2 Inch Boat Trailer Frame
    Since you've got a boat trailer, you'll want to use something that offers a good level of corrosion resistance. We have two different u-bolts that would work for you, one that's zinc plated # CE15252A and one that's stainless steel, part # CE15253A. If you're in a freshwater environment, the zinc plated u-bolt would work fine, but if you're using your boat in saltwater, you might consider the stainless option.

  • What Size Roller Bunks for 16 DLX Carolina Skiff Boat Trailer
    I checked with Carolina Skiff and they were able to give me the trailer specifications for the size 1655 DLX. They recommend that you use 2" x 6" wood, carpet-covered bunks that are 10' 6" long spaced 40" apart when measuring from the outside edge of the bunks. They also require that the front end of the bottom bunk extend past the flat bottom of the boat. If you'd like to stick with the wooden bunks they recommend, we do sell the marine grade carpeting in the 18" width, # CE11349. If...

  • Dimensions of CE Smith U-Bolt Threads # CE15252A
    I went out to the warehouse and pulled a CE Smith U-Bolt, part # CE15252A and took some measurements for you. The threaded portion is 2-1/16". The outside width is 4". The outside length is 3-1/8". Check out the photo of the U-Bolt along with the dimensions I made for you at right.

  • Recommended U-Bolt for 3 Inch Wide x 1-1/2 Tall Trailer Frame
    For a u-bolt that will fit a 3" wide x 1-1/2" tall trailer frame you can use the CE Smith U-Bolt part # CE15252A which is 3" long x 3-1/8" wide x 7/16" diameter. Please note, the u-bolt width must be wider than the width of your frame in order to attach, otherwise it would not work which is why you need the 3-1/8" width listed above. The 3" length is the shortest we offer for the above width.

  • Will the Fulton F2 Trailer Jack # F1413040134 Work with a 2 Inch x 3 Inch Frame
    You can install the Fulton F2 Jack, # F1413040134, on your trailer, but you will need to pick up smaller u-bolts. The u-bolts included with this jack fit 3 inch x 3 inch and 3 inch x 4 inch frames. You could pick up two of the CE Smith U-Bolts, # CE15252A. These u-bolts are 3 inches long x 3-1/8 inches wide. I tested it with the Fulton F2 Jack, # F1413040134, and they fit. The shorter length and longer threads should work well with your 2 inch wide frame.

  • How Does the CE Pyramid Washer # CE10806 Fit Against a U-Bolt Nut
    After speaking with my contact at CE Smith, I found the CE Smith Pyramid Washer # CE10806 fits against the nut high side up. To demonstrate how this would work, I have included a video that should be helpful. This washer works best with the CE Smith U-Bolt # CE15252A, a multi-purpose U-bolt intended for use on trailer to help secure brackets, mounts, and cargo. It is constructed of sturdy, zinc-plated steel, and it comes with mounting hardware.

  • Recommended Roller Bunks for 14 ft Alumicraft Trailer
    The Dutton-Lainson Boat Trailer Deluxe Roller Bunk - 5' Long Sections - 12 Sets of 3 Rollers # DL21741 would just allow the small v you mentioned to sit on top of the flat roller. Another option is to use the 2 roller style of the Boat Trailer Standard Roller Bunk - 5' Long - 12 Sets of 2 Rollers - by Dutton-Lainson # DL21755 which have a little more flexibility. You can attach this roller bunk with the Boat Trailer Roller Bunk Bracket for Dutton-Lainson Roller Bunks # DL21762 instead...

  • Installation of Roller Bunks on Trailer for World Cat 26 Foot Long Boat
    The Dutton-Lainson Boat Trailer Deluxe Roller Bunk - 5' Long Sections # DL21741 are a great option to make loading and launching your boat easier. You will want to remove the bunk boards for the installation or at the very least add some spacers ad the wheels are taller on the top and bottom of the bunk boards so installing them directly on the bunks would need the wheels from rotating. Most installations use the Boat Trailer Roller Bunk Bracket for Dutton-Lainson Roller Bunks # DL21742...

  • Are Longer Axles Available For Single Axle Pontoon Boat Trailer
    I did some research on your 1994 Sylvan Pontoon boat and found that the beam is 8-ft. The pontoon boat trailers I was able to find information on said the distance between the center of the bunks for a boat with an 8-ft beam are spaced 72 inches apart. I have attached a photo that shows how the bunks are placed under the pontoons. If your trailer frame is wide enough to be able to place the bunks with those dimensions then you would not need to try and extend the axles. You may want to...

  • Installation of UWS Truck Bed Tool Chest UWS01044 in 2018 Sierra Denali 2500 HD
    The UWS Truck Bed Tool Chest # UWS01044 does require you to drill and use your own hardware to secure it in your truck bed. The choice of hardware is up to you; you could use screws, nuts and bolts or even u-bolts like # CE15252A if you prefer. Your spray-on liner will not be an issue for installation. Dimensions are shown in the linked diagram. This USA-made tool chest features 8 cubic feet of internal volume and its corrosion-resistant aluminum construction and foam-reinforced lid mean...

  • Recommended Roller Bunk Assembly for 3 Wide Trailer Frame
    Yes, the mounting holes on a roller bunk assembly bracket would need to be spaced apart farther than 3" in order to fit a 3" wide frame. Instead of using the CE Smith Spool Roller Assembly part # CE10451G, I recommend using a combination of the brackets part # MBSPB, roller part # YR510Y-5, shaft/nuts part # CE10722A, and u-bolts part # CE15252A. Roller assemblies can be installed on trailers in a variety of different ways but in order to attach them directly atop a 3" wide frame rail like...

  • Need 3 Inch Center-Detented U-Bolts for Older Cargo Box
    Thank you for providing the photo and width dimension of the u-bolt for which you are seeking a replacement. If you can provide us with the make and model of your cargo box, we can research availability of exact replacement parts. We do not currently have any u-bolts with a center detent as shown in the photo. However, I can recommend some multi-purpose replacement u-bolts that may work for you even though mounting a cargo box is not necessarily their intended purpose. Part # CE15502A...
