D5 Belay / Descender, 1/2" (RD)

The D5 work and rescue descender has been developed for the North American Fire Rescue and Tower Climbing markets which typically use 1/2 inch (12.7mm) rope.

Well suited for the Industrial Height Safety, Rope Access, Edge Management, Arborist and Search & Rescue industries.

Easily controls 500 pound loads
Side plate closes with low-profile spring loaded safety catch
Simple functional design
Load or remove rope without removing rigging carabiner


Double-stop device with an auto-lock function
Activated whenever the operator releases the handle; and a panic-brake function, which is not overly sensitive in normal use.

Double-locking safety mechanism
In addition to the locking button, the side plates are designed so that the plates cannot be rotated open while under load due to the position of the carabniner.

Easy to use
Easily attach and detach the descender from the rope without having to detach from the harness therefore eliminating the risk of accidental dropping of the device.

Progressive cam action
Creates precise control during low or high speeds. The cam is made from a solid piece of high grade stainless steel for maximum durability even in harsh environments such as Geotech work.

The D5 work and rescue descender 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.

Rotate handle counter-clockwise to lock in place
Rotate right to descend or lower load
Rotating handle too far clockwise will engage panic stop function
Continued clockwise rotation re-sets the unit

Can be used for progress capture in hauling systems and allows rapid conversion between raising and lower.
