ISC D4 Descender ISC D4 Descender ISC D4 Descender ISC D4 Descender ISC D4 Descender
Special descender/belay device that easily controls 500 lbs loads.
The side plate closes with a low-profile, spring-loaded safety catch.
Simple, functional design. It can be placed onto the rope without removing the rigging carabiner.
Rotate the handle counter-clockwise to lock it in place.
Rotate right to descend or lower load.
Rotating the handle too far clockwise will engage the panic stop function.
Continued clockwise rotation re-sets the unit. The D4 is a true panic stop device rather than a panic brake device.
The difference is that once the panic stop is activated, no other force must be applied to the device.
A panic brake-style device requires a force input to continue the braking function.
It can be used for progress capture in hauling systems and allows rapid conversion between raising and lower.
For 3/8" - 7/16 (10.5 - 11.5mm) ropes.
See the D5 for use with 1/2" ropes.
WARNING This product can expose you to chemicals, including nickel acetate, which is known to the State of California to cause cancer.
