The Topcon Sensor Holder 6 is designed to hold the Topcon LS-80 and LS-70 laser receivers. The clamp holds the receiver securely, so you do not have to worry about it getting damaged. It can then be mounted to a tripod or other wide surface, to keep it where you need it. It also works to being attached to a leveling staff. The static thread keeps the side of the clamp from being in the way. It is strong and lightweight, making it sturdy enough for the job site.
