The SitePro 4364 is meticulously designed to offer a non-slip grip, preventing users from over-tightening the clamp and potentially crushing the prism pole. A crucial tool for surveyors, it facilitates the setup of a freestanding GPS antenna pole or prism pole. The open-face head with an anti-crush clamp accommodates poles with a diameter of 1 to 1.25 inches (25.4 to 32 mm), and 1.5-inch (38 mm) poles can be effortlessly attached through the top of the open-face clamp. Featuring a unique anti-crush locking system, the SitePro 4364 ensures non-slip quick clamping. It accommodates poles ranging from 1 to 1.5 inches (25 mm-38 mm) in diameter, allowing for quick and easy pole setup. The legs can be easily adjusted independently with thumb-release push buttons, and the replaceable points enhance durability.
