Open jaw/galvanized jaw clamps, also known as open roller clamps, are designed to provide an adjustable fastening connection that provides tension between two components (typically wire ropes and suspension points). They meet the working load limit performance requirements of ASTM F1145-05 Type 1 Grade 1 (formerly known as US FED SPEC FF-T-791b).
The open design provides a clear indication of thread extension, while both jaws are equipped with safety pins to prevent unintended opening and ensure a secure connection. Hot-dip galvanized coating provides additional protection against corrosion in normal environments.
