These clamps enable you to mount 1-1/2" square tubing on the top or bottom of an I-beam on your boat trailer or a boat lift. Its galvanized steel construction resists rust and corrosion.
Features:
Specs:
This set of clamps makes 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.

Awesome product great for large I beams
It was not exactly like the picture but was exactly what I needed. Possibly a better version than the picture. Fast shipping and reasonable price.
Just what I needed to hold the guild bars in place.
Thank you
Easy to order, correct item delivered, easy to install, great purchase!!!

I am glad these come in a pack of two, I sometimes don’t get on the straight and had to change the pieces out again. The product is good my boat control sometimes not..,
These things are excellent. Perfect replacement part and hold up very well.
Screws were a little short. I have a 7 and a half inch I frame on my boat trailer, Thanks, it will work out fine.
holds guide-ones in place best price e trailer
Good parts, great service, extremely fast shipping. You just can't go wrong.
It's exactly what I was looking for.
Fast service & item was exactly what we needed
Great product for I BEAM trailers. E trialer was awesome to deal with. Fastest and cheapest shipping around.
Perfect fit, heavy-duty galvanized steel is a lot stronger than the originals I'm replacing so these should last forever.
Excellent service and ooutstanding products as always!
Guide-on's were as advertised. Straight forward quick and simple installation. Seem to be very sturdy. The option of mounting on the top or bottom of the I-beam trailer frame is a great feature.
Have not installed the brackets yet, but they are better built than the ones on the trailer when I bought it. Ordering was easy and delivery was exactly when they said it would be. Looking forward to purchasing other products from them
The bottom portion of the I-beam holding the guide poles broke off.(was originally drilled and held with 2 u-bolts. Saw this product and purchased. Transferred guide poles to upper i-beam with these and have not had any issues. Saved me a big chunk of change by not welding the broken i-beam.
These CE Smith I-Beam Clamps worked great.
I had some guide on post custom made from heavy duty tube steel and these clamps were exactly what I needed.
Shipping from etrailer.com was very quick.
Great service, super fast, great price, quality of product , great.
Boat trailer is out of town, so no pictures

All good!
I replace bolts,washers and nylock nuts with stainless. I would have gladly paid a few more dollars for them to supply stainless hardware. The brackets themselves are hot dipped galvanized very nice.
I just rec'd them today, so I really can't give a valid review of their quality yet. I probably won't even get them installed for a couple of weeks.
That said, the clamps look solid and as advertised. The ordering and delivery was excellent.
The item came quicker than I expected and only took a few moments to install.

After a year the clamps still work great with no signs of rust.
Should come with zinc plated hardware to prevent premature erosion from dissimilar metals.
