PETZL
OK SCREW-LOCK - M33 SL &
OK TRI-ACT M33 TL

The OK has the advantage in several applications where you want to keep your TIBLOC, TRAXION, FIXED SIDE PULLEY or other device centered on the biner for reduced friction and smooth operation. It is a big help in rigging mechanical advantage haul systems with ASCENSION or BASIC ascenders. The OK LOCKING features a hooded gate and smooth internal surfaces and the Keylock latch system which eliminates the parts that can normally snag on your harness and gear. As an added safety reminder a red warning band (on gate) alerts you to an unlocked biner. Nice to always have a few on your rack! Made in Italy, delivered anywhere in the U.S.
