Our Rotary Laser Receiver Clamp easily threads onto all of our Rotary Laser Receivers (3711, 3712, & 3714). The Receiver Clamp gives you the ability to attach the Rotary Laser Receiver to a Grade Rod or other types of material in order to accurately measure your heights & elevations on the jobsite. Designed to be adjustable and durable, the Receiver Clamp has rubber pads that assist in creating a sturdy clamp force onto the desired material. It also features an embedded bubble vial to ensure that you stay plumb no matter what material you are working on.
