PROTECHâ„¢ Aluminum Key-Lock Carabiner
The PROTECH™ Aluminum Key-Lock Carabiner is a lightweight, high-strength connector designed for rescue, rope access, industrial safety, and technical rope operations. Its patented key-lock nose design prevents snagging on rope, webbing, and hardware, allowing smooth clipping and unclipping even in demanding environments. The optimized D-shaped frame maximizes strength while maintaining a compact, easy-to-handle profile.
Constructed from anodized aluminum, the PROTECHâ„¢ series offers multiple gate configurations to suit a variety of operational requirements, including Screw-Lock, Manual-Lock, and Auto-Lock options. The wide 1-inch gate opening accommodates railings and anchor points uncommon for a carabiner of this size, while etched safety indicators support fast visual confirmation during use. Every carabiner is proof loaded and individually serialized for quality assurance and traceability.
