ISC R-Alf™

The ISC R-Alf™ is an auto-locking rescue hauler suitable for rescue, confined space and suspension systems. The pulley has an over-speed brake built in that will lock on and hold when a fall occurs.  The load rated becket eye on the R-Alf™ can be used in combination with prussik pulleys to create a 3:1 or 5:1 hauling kit.
