The clamps are designed to protect surfaces and prevent slipping with their textured rubber jaws. Made with 1010 chrome plated steel, they are stronger than stainless steel and have a large ergonomic handle that allows for faster spinning and proper leverage for securing and releasing clamps. These clamps are versatile and can grip round, square, or rectangular tubing, as well as other common and irregular shapes. The reinforced jaws and 1010 chrome plated steel shaft make them durable and reliable. They are available with different jaw sizes and can be used for various purposes, including mounting cameras and lighting equipment with 3/8″ female holes.
