Oval carabiner for use with pulleys and ascenders with screw lock closure

The lightweight OK Screw-Lock carabiner is made of aluminum. It has an oval shape that allows optimal loading of devices with a wide cross-section, such as pulleys, rope clamps and mobile fall arresters. Its fluid interior design and Keylock system facilitate handling. OK can be connected to the CAPTIV bar to favor positioning of the carabiner along the major axis, to limit the risk of it flipping and to keep it integrated with the device. This model offers a manual screw-lock with red band that provides a visual warning when the carabiner is unlocked.

  • The symmetrical oval shape allows optimal loading of devices with a wide cross-section, such as pulleys, rope clamps and mobile fall arresters
  • Aluminium carabiner whose light weight reduces the weight of equipment the worker at height needs to carry
  • May be used with a CAPTIV positioning bar to favour loading of the carabiner along the major axis, to keep it integrated with the device, and to limit the risk of it flipping 

Easier Handling

  • Fluid interior design limits the risk of having a catch point and facilitates rotation of the carabiner

Petzl OK Carabiner Screw Lock

I have used these for a long while both for climbing and more recently to hold load bearing spars for very heavy rails for my vintage stall! The lightweight OK carabiner is made of aluminium and are noticeably lighter than other similar looking versions. If this is an issue this is a must have product. A classic oval shape is used with a fairly wide section that allows flexibility in many circumstances-even when wearing gloves, more typically for pulleys and rope clamps. It is excellent for clipping on to heavy objects, props and so on. It has a Keylock system to facilitate handling to prevent accidental release. Look up 'automatic TRIACT-LOCK system' or 'manual SCREW-LOCK system' and find the one you need.
