Rated 3 out of 5 by JHET Works
Purchased these because I didn't want to drill lots of holes in my boat railings. They work for the most part okay if you attach them in the center portion of the boat. But if you try and use them toward the front or back of the boat, they lean at about a 20degree angle, so am having to work on some shims. Also the knob on the handle is not very substancial.

Rated 5 out of 5 works great
Works great on my aluminum john boat. They grip and hold onto the rounded gunwall with no slippage and no scratches. Used them on a friends pontoon boat with the same results.

Rated 4 out of 5 by CYCLEDIKEL Happy with purchase
If you need to temporarily mount something to the rails this can not be beat. It looks nice and is very flexible and functional. The swivel however has been very cheaply affixed. Rather than being pressed fit it is "clamp squeezed forced" for want of a better phrase. It makes tightening and loosening more difficult than necessary.
