About: Petzl - Ok Carabiner

Aluminum carabiner whose light weight reduces the weight of equipment the worker at height needs to carry

Symmetrical oval shape allows optimal loading of devices with a wide section, such as pulleys, ascenders and progress capture pulleys

Facilitates manipulations:
  • Fluid interior design limits the risk of having a catch point and facilitates rotation of the carabiner
  • Keylock system to avoid any involuntary snagging of the carabiner
  • The H-profile contributes to better grip, protects the markings from abrasion and reduces weight
H profile:
  • Ensures an optimal strength/weight ratio
  • Protects markings from abrasion
Available in three different locking systems:
  • SCREW-LOCK: easy-to-open system, locking or not, according to the need of the user. The red band provides a visual warning when the carabiner is unlocked. This system is suitable for difficult environments where contaminants (mud, ice) could cause an automatic locking system to jam.
  • TRIACT-LOCK: automatic locking system designed for frequent manipulation. Triple-action opening by raising and turning the sleeve, then pressing on the gate.
  • BALL-LOCK: automatic locking system designed for frequent manipulation, with lock indicator. Triple-action opening by pressing on the green indicator, turning the sleeve, then pressing on the gate. The green button indicates when the gate is locked.
