Petzl OK H Frame

The symmetrical oval shape is specifically designed to center devices like pulleys, ascenders, or rope clamps. Unlike D-shaped carabiners, which can shift under load, the OK H-Frame ensures your gear stays perfectly positioned for consistent performance.

The H-frame design removes excess material where it isn't needed, significantly reducing weight without compromising strength. It also provides a more ergonomic grip and helps protect the carabiner's markings from abrasion over time.

Yes, the keylock system eliminates the small hook found on traditional carabiners that often snags on slings, ropes, or gear loops. It creates a smooth, snag-free nose that makes clipping and unclipping much faster and less frustrating.

The OK H-Frame is a reliable choice for technical environments. Its fluid interior design minimizes areas where debris can accumulate, and depending on the locking mechanism you choose, it can be more dependable than automatic systems when working in conditions with mud, ice, or grit.

The OK H-Frame features a visual locking indicator, which provides a quick, clear way to verify that the gate is securely closed. It is a simple but essential safety feature that gives you peace of mind during complex rope maneuvers.
