Spectra Precision C50 Rod Clamp for CR600 Receiver clamps to Measuring Rod

Mount Your CR600 Receiver Fast and Secure with the Spectra Precision C50

The Spectra Precision C50 Rod Clamp is the purpose-built mounting solution for attaching the CR600 laser receiver to standard surveying grade rods. Designed for contractors who need a fast, repeatable setup across multiple jobsites, the C50 delivers a rigid, vibration-resistant connection that keeps your receiver locked at the correct elevation while you work. No improvised mounts, no wasted time — just a solid interface between your rod and receiver so your crew can focus on hitting grade.

Overview & Jobsite Applications

The C50 is engineered specifically for field conditions where equipment changes hands between crew members and moves frequently between active work areas. Its simple clamp-and-lock mechanism lets operators position the CR600 at any height along the rod and secure it within seconds, without tools. Whether you're running pipe grades, verifying subgrade elevations, or checking finished floor levels, the C50 gives your receiver a stable platform that won't slip under normal working vibration or contact. It's an essential accessory for any crew running a Spectra Precision CR600 in a rotating multi-site operation.
