Safe. Durable. Lightweight. 


30 ft. (9.1m) of 3/16″ (5mm) stainless steel wire rope with swivel snap hook.

The Ultra Lok is a long standing, trusted name in fall protection. 

Ultra Lok self retracting lifelines (SRL’s) are rugged, lightweight, comfortable, efficient safety devices.  Stainless steel components, an anti ratcheting brake system and a semi sealed design provide the user with a system built to last.  You can have complete confidence, safety and reliability in our SRL’s.  An SRL’s lifeline will extend as the user moves away, and retract automatically enabling the user to move about within a recommended working area at normal speeds. Should a fall occur, a speed sensing brake system will activate stopping the fall and reducing the forces imposed on the user to safe levels.
