Petzl William Ball-Lock Carabiner (M25) — Gray/Yellow, New/Old Stock

The Petzl William Ball-Lock Carabiner is a large-format, pear-shaped HMS carabiner engineered for belay, rappel, and rescue applications where security, control, and ease of use are non-negotiable. Featuring Petzl's reliable ball-lock gate mechanism, the William M25 provides an intuitive single-handed locking system that minimizes accidental opening while keeping operations smooth and efficient on the wall or in the field.

Key Features:

• Ball-Lock Gate System – Single-action locking mechanism that automatically locks on closure, reducing the risk of accidental gate opening during critical operations
• Large HMS Pear Shape – Optimized geometry allows smooth rope movement and excellent compatibility with belay devices, ATC-style tools, and Munter hitches
• Lightweight Aluminum Construction – High-strength aluminum alloy delivers an ideal strength-to-weight ratio for climbing, rescue, and rope access applications
• Wide Gate Opening – Generous gate clearance allows fast, easy clipping onto anchors, harness belay loops, and rigging points
• High Load Rating – Certified to meet rigorous CE and UIAA safety standards for professional and recreational use
• Dual-Color Gray/Yellow Design – High-visibility yellow accents allow quick identification in multi-carabiner setups and low-light environments
