Petzl William Pear-Shaped Locking Carabiner 3-Pack – Screw-Lock or Ball-Lock for Belaying

Overview: William Carabiner by Petzl

The WILLIAM carabiner blends a large-capacity basket with an ergonomic, pear-shaped silhouette designed to simplify handling at belay stations. Crafted from lightweight aluminum, it supports easy feeding of ropes and gear while maintaining a secure connection in dynamic climbing settings. Available in two locking systems, SCREW-LOCK and BALL-LOCK, it’s built to adapt to varied conditions and user preferences.

Key benefits at a glance

• Optimized size and shape: The basket accommodates multiple items and offers a practical profile for Munter-hitched belays.
• Keylock system: Reduces the risk of snagging during clipping and unclipping, even with gloves on.
• Ergonomic for gloves: An asymmetrical pear form facilitates opening and manipulation of the locking mechanism.
• Two locking options: Choose SCREW-LOCK for reliability in dirty or icy environments, or BALL-LOCK for automatic security.
• Visual safety cue: A red band on the screwgate signals when the gate is unlocked.

What this means on the wall or at the crag

In real-world use, the William carabiner supports organized belay stations and efficient hammering of Munter-hitched belays. The large capacity helps you connect a variety of items—climbing gear, ropes, binners, and quickdraws—without rearranging hardware constantly. The combination of a smooth Gate operation and a Keylock design translates to quicker, more confident movements when gear is under load or in cold, damp conditions.

Consider the two locking systems as practical adaptations for different environments. Screw-Lock provides a straightforward, robust solution when mud, ice, or grit could interfere with automatic systems. Ball-Lock offers hands-free security, which can speed up transitions during multi-pitch routes or busy crags. The 3-pack format gives you ready redundancy or the option to equip multiple belay stations without sourcing additional components.

Features that stand out

• Large-capacity basket for equipment and rope management
• Asymmetrical pear shape that enhances grip and one-hand operation
• Keylock system to minimize snag risk during handling
• SCREW-LOCK variant with a visible red unlocked indicator
• BALL-LOCK variant for automatic locking in varying conditions

Whether you’re climbing blue ice, rock routes, or jammed into a craggy belay, Petzl WILLIAM delivers a dependable, versatile choice for front-line belay setups. It’s designed to be a practical, repeatable tool in your rack—one that supports comfort, control, and clear hub-to-hub gear flow at the anchor.
