Petzl William Ball Lock 3 Way Carabiner - Grey

The Petzl William Ball Lock 3 Way Carabiner is a large-capacity aluminium connector designed for professional work at height where versatility, secure locking, and smooth handling are essential. Its asymmetrical pear shape provides generous internal space, making it well suited to building anchors, managing complex systems, or connecting multiple components efficiently. Designed for arborists and rope access professionals, this carabiner balances strength, usability, and reduced weight for daily professional use.

Large capacity shape for efficient system building

The pear-shaped profile offers a wide opening and ample internal volume, allowing multiple connectors, ropes, or devices to be clipped without crowding. This shape also supports the use of a Munter hitch when required, adding flexibility during work positioning or retreat scenarios. With a 27 mm gate opening on the Ball Lock version, the carabiner supports smooth and confident clipping, even when wearing gloves or working in busy setups.

Ball Lock automatic locking for controlled security

This version is equipped with the Ball Lock automatic locking system, featuring a triple-action gate and an integrated lock indicator. This provides clear visual confirmation of the locked state, helping reduce the risk of user error during critical operations. The locking action supports secure connections while remaining intuitive to operate, making it suitable for repeated clipping and unclipping throughout the working day.

Lightweight aluminium with refined handling

Manufactured from aluminium, the William Ball Lock weighs 90 g, helping reduce overall equipment load without compromising strength. It delivers a major axis strength of 27 kN, supporting demanding professional applications. The fluid interior design encourages smooth rotation under load, while the Keylock nose helps prevent snagging on ropes, slings, or hardware. The H-shaped cross-section improves the strength-to-weight ratio and protects markings from abrasion during regular use.
