- I-Beam Clamp
- Galvanized Steel
- CE Smith
Four of these clamps enable you to mount 1-1/2" square tubing on the top or bottom of an I-beam on your aluminum boat trailer or a boat lift. Its galvanized steel construction resists corrosion.
Features:
- Heavy-duty clamp secures 1-1/2" square tubing to an I-beam
- 4 Clamps (each sold separately) are required for (1) I-beam
- Galvanized steel construction is sturdy and resists corrosion
- Quantity: 1 clamp
- Made in USA
Four of these clamps make it easy to attach 1-1/2" tubing, such as a roller-style or bunk-style guide-on, to an I-beam on an aluminum trailer without drilling. They mount on the inside and outside of the I-beam for a snug connection.
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.

Definitely a great heavy duty mounting bracket. I've been looking for something like this for a while. This was needed to secure my boat transom to my trailer. I was tired of using ratchet straps from the top of the transom deck lift hook down to the trailer.
I've seen many brackets , but this works awesome and was an easy install.

Heavy-duty, ht-dipped galvanized and the best price around. Could not find anyone else that sold these individually. Should hold up well on my saltwater trailer. Shipping was reasonable and fast. Good job etrailer!

Product was delivered promptly, was reasonably priced and was exactly the product for which I was shopping. This clamp is used to secure an “L-shaped” piece of square tubing, approximately 7 ft long end-end, to the bottom side of an I-Beam on a boat trailer. Given that the function of this is to act as a guidepost for putting a boat on the trailer, it will get bumped regularly, by a heavy boat. The result is that this design is poor for the application as these clamps cannot hold up to the amount of abuse they take. All that said, this was the exact replacement part I needed and etrailer.com was stellar!

Very well make & solid. I originally bought them for a different use (side bunks), but I will soon be using them when I add a larger step on each rear side of the trailer. These will be prefect for the application.

etrailer was the only place I could find this part separately. Instead of a $4 piece to repair the failed OEM bracket on my trailer guides I was looking at a $30 kit. This design eliminates the sharp bend on my original where it cracked. Shipment was quick and complete.
Thanks for making this easy on us DIY'ers etrailer.

This thing is solid. Very strong. I had a round aluminum guide posts which bent and broke in a strong current. I sanded this new guide post lightly and painted it with Rust-Oleum Universal Bonding Primer, which is made for galvanized steel, because I use in salt water. Then I top coated with gloss white enamel.
Very happy with this purchase. It arrived 3 days before promised date. Much stronger than the aluminum posts I am replacing. Exceeded my expectations. Very happy with everything I have ordered from etrailer.

The parts themselves seem fine. I was just disappointed that it did not come with the bolts to install. The ones I have are a different size, so now I need to find the correct bolts.

view full answer... - What Size And Length Bolts Should I Use To Install The CE Smith I-Beam Clamp CE27681G?Hey Tom, thanks for reaching out, and good question, and this one’s actually simpler than it looks once you see how CE Smith sets these up. The CE Smith I-Beam Clamp # CE27681G is designed around 3/8" hardware, not anything bigger. The clamp itself will accept up to a 3/8" diameter bolt, which is the size you want to stick with. For length, there isn’t one exact number because it depends on your I-beam flange thickness and what you’re clamping to it. For a 3.5" beam, you'll probably...
