The D5 Descender has a double safety locking mechanism, which means when loaded, the side plates cannot be rotated open due to the positioning of the carabiner and the push button click-lock safety closure. The D5 is easy to attach/detach from rope without detaching from the operator’s harness, therefore eliminating the risk of accidental dropping of the device. It is easy to back-feed the rope through the D5 and therefore it can be used for smooth ascending or for emergency hauling.

The D5 Descender allows for controlled descent at different speeds. A user can move slowly, or get going much quicker than they can on a Petzl ID. However, it still has the anti-panic in case a user pulls the handle too hard. Handle spins all the way around, and gives audible clicks as it resets. NEW handle position is approx. 25 degrees back from the origional protptype position allowing for a more ergonomic position for the user.

Device is suitable for a two-person rescue without extra friction (i.e. using an extra carabiner with a redirect).

The D5 Descent Device opens with a push button. Button is easy to open, even with gloves, but is difficult to open under load, decreasing risk of accidental opening. Button audibly clicks when device is closed.
