PearLock Screwgate Carabiner

Designed for alpine climbers, rigging specialists, and mountain guides managing complex belay stations and multi-pitch descents, the Black Diamond PearLock Screwgate Carabiner combines smooth rope handling with high structural strength. Its pear-shaped HMS geometry features an enlarged basket area that accommodates Munter hitches, dynamic belay devices, and multi-rope rigging without binding or localized rope wear. Built to withstand high-altitude Himalayan freezing cycles and dusty rock terrain, the non-freezing screwgate sleeve locks onto the gate body rather than the nose, ensuring seamless operation under load.

PearLock Screwgate Carabiner Features

• Hot-Forged I-Beam Construction: Strategic material placement that reduces overall carabiner weight while maintaining structural strength.

• Enlarged Rope-Bearing Surface: High-radius basket design optimized to reduce rope friction and increase carabiner longevity.

• Type H (HMS) Geometry: Certified pear-shaped profile designed for dynamic belaying using a Munter hitch or dedicated belay device.

• Non-Binding Screwgate Sleeve: Engineered sleeve that locks directly onto the gate body (not the nose), preventing thermal binding under weight.

• Keylock Nose Interface: Notchless, catch-free nose geometry to prevent snags on webbing, rope loops, and anchor hangers.

• 7075-T6 Aluminum Composition: High-strength aluminum alloy body for enhanced fatigue and force resistance.
