Msa Safety 506222 Split Mount Pulley Confined Space Entry

Product Description

The MSA SAFETY 506222 is a split mount pulley designed for confined space entry and rescue operations. It attaches to compatible tripod and davit systems to lift or lower materials and personnel during confined space work. The split mount design allows for quick attachment without threading a rope or lifeline through the block, saving setup time in the field. This pulley meets OSHA regulations and holds ANSI A10.32 and CSA certifications, making it suitable for use in compliant confined space entry programs. It is installed and used by safety professionals, industrial riggers, and confined space entry teams.

This pulley is used in industrial and construction environments where confined space entry is required. Typical applications include non-entry rescue operations, personnel retrieval, and material handling in tanks, vaults, manholes, and similar restricted spaces. The lightweight, portable design makes it practical for job sites where equipment must be transported and set up quickly. It also finds application in welding and painting operations where materials or workers must be raised or lowered into a confined space.
