Installation Notes

This wrench is a hand tool requiring no installation. Power down or de-energize any equipment before loosening or tightening fasteners on live systems. Use the appropriate head angle to maintain full contact with fastener flats and reduce rounding risk. Inspect the chrome finish and jaw surfaces periodically for wear that could compromise grip on fastener flats.
