The updated design of the clamps allows for use with any light or accessory, by providing a flat mounting surface. Available in 9 sizes: 0.75 inch, 1.00 inch, 1.25 inch, 1.50 inch, 1.75 inch, 2.00 inch, 2.25 inch, 2.50 inch and 3.00 inch. Clamps are sold as a pair (2), and feature a rubber insert which allows for additional adjustability in mounting diameter as well as protecting the finish of the tube you are mounting to. Larger size clamps feature a set screw to prevent the clamp from rotating around the tube. Clamp sizes 0.75 inch through 1.75 inch feature a through hole for M8 mounting hardware, while sizes 2.00 inch through 3.00 inch have a M10 through hole. Mounting through holes can be drilled out or used with spacers to adjust size.
