Description
Product Overview
The Spectra Precision C45 Clamp is engineered as a dedicated mounting accessory for the HL450 series of laserometers and receivers. Constructed from a high-strength alloy steel body, the clamp delivers a robust, corrosion‑resistant platform that can endure the harsh conditions of outdoor surveying, construction, and industrial inspection. The fixed‑jaw mechanism, combined with a precision‑machined screw, provides a lock‑tight grip that eliminates slippage even when subjected to continuous vibration or sudden impacts. Dimensions of 8 x 8 x 3 inches and a lightweight design of 8.82 ounces make the C45 easy to transport while still offering the structural integrity required for demanding field applications. The model number C45 reflects its position within Spectra Precision’s legacy of reliable clamping solutions, a lineage that dates back to 1965 and continues to set industry standards for accuracy and durability.

Usage
Designed for professionals who require precise alignment of laser measurement equipment, the C45 Clamp excels in a variety of real‑world scenarios. Surveyors can quickly attach the clamp to a standard rectangular grade rod, allowing the HL450 receiver to maintain a stable orientation while capturing distance data across uneven terrain. Construction managers benefit from the clamp’s rapid‑adjust knob, which reduces setup time on busy job sites where every minute counts. In addition, the clamp is suitable for use in utility mapping, civil engineering, and environmental monitoring where reliable data collection is critical. Its compatibility with the HL450 series ensures a seamless fit, eliminating the need for custom adapters or additional hardware. Whether deployed on a portable tripod, a fixed pole, or a temporary scaffold, the C45 Clamp delivers consistent performance that professionals depend on for accurate measurements.
