The Stabila BST-K-L Column Construction Tripod extends between 98-220cm in height. The Stabila BST-K Construction Tripods have a removable head that allows quick and easy mounting of the laser, simply remove and head and attach onto your laser before fastening the head onto the tripod. The lifting system with crank handle allows the height of the laser to be raised and locked off at a range of heights. The built-in air cushion lifting system allows the central column to descend gently, even if the user forgets to lock off the tripod. This prevents accidental damage to the laser. Each leg of the tripod can be adjusted individually and each spiked foot has rotatable rubber shoes, for scratch-free use indoors. Also fitted with a high quality chain spread stopper.
