ISC Double Sheave Re-Direct Pulley

ISC Double Sheave Re-Direct Pulley

PUL150

Redirect your doubled climbing line with this double re-direct pulley from ISC. This is the easiest way to redirect your doubled line, with swinging side plates and side by side aluminum sheaves. With the swing cheek design this makes for a great addition to DdRT redirect setups.

The angled design of the upper side-plates keeps the ropes captive and running correctly on the sheaves. This pulley is made from lightweight aluminum and is nice and compact so that it won't take up much room on your belt.
