3M DBI-SALA 50 ft Sealed - Blok Self Retracting Lifeline - Magnetic Retraction Control (MRC) 3400846 - 50 ft (15.2 m)
3M DBI-SALA Sealed-Blok Self Retracting Lifeline - Magnetic Retraction Control - Cable 3400846 - 50 ft. (15.2 m)
50 ft. (15m) of 3/16" (5mm) 316 stainless steel wire rope with swivel snap hook, stainless steel anchorage carabiner and magnetic retraction control.
These Sealed Blok self retracting lifelines (SRL's) incorporate a patented concept that separates all dynamic components, including the motor spring and brake, from foreign elements such as grease, moisture and dirt. In addition, a patent pending technology to reduce retraction speed limits the effects of a released lifeline on the SRL as well as surrounding equipment. Our sealed SRLs are backed by decades of proven field service for absolute confidence, safety and reliability. 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.
