    Best rail clamp I’ve seen. I use it to support a Lowrance depth sounder on my G3 1860.

    My boat has 1.25″ railings. Nobody stocks components to fit 1.25 except for Mantus. These things are “bomber”. Nicely done. I haven’t been disappointed by any of your products yet….keep it up.

    These are extremely well built (like all Mantus products) and fit securely to our 1″ rails. Couldn’t be happier.

    I love the stainless clamps but had one issue that others may have. One of the clamps locked on to my 1″ rail perfectly and did not rotate at all. The other one in the set locked on but rotated somewhat around the rail when even a small amount of pressure was applied. I checked both on multiple different areas of the rail and found the same thing, and both have the same piece of rubber on the inside of the clamp. I assume that one of the clamps was made just a fraction too large. However when I put a small piece of “Gorilla tape” on the inside of the clamp it worked well and no longer slipped around the rail when pressure was applied. Nevertheless I would highly recommend these and look forward to many more innovative Mantus products!

    I’m using 4 to mount 2 hardwood rails to mount kayaks off of boat . They secure and provide easy on off when you are using kayak. You can remove easy, very good quality. Thx

    I used these to mount rod holders to the rails on my 2008 Sea Pro SV 1900 CC. These are great in this application in that they allow rod holder adjustment or removal without tools. They also look great. I would add a picture but the attachment button doesn’t seem to be working.
