AdirPro 79060 [790-60] Heavy Duty Column Clamp

The AdirPro Heavy-Duty Column Clamp provides stability and support for heavy instruments with 5/8-11" threads. A must for surveyors, it's designed to support all 5/8 x 11" instruments such as lasers and theodolites with a maximum load of 2,200 pounds (1000 kg).

The clamp is guaranteed to be durable with its structural aluminum construction and stainless steel hardware. Its adjustable column rotates and moves vertically, while the locking lever secures the column for proper instrument orientation. With the aid of a ratchet clamp, it ensures a solid connection for both round and square columns. A fine adjustment bolt and a rubber-coated ratchet clamp handle provide extra stability and grip. The centerline of the 5/8 – 11" stud to the adjustable column measures 15 inches. 

The AdirPro Heavy Duty Column Clamp also features a rubber washer to protect workers' fingers and a 10-foot, 2-inch nylon strap.
