Aluminum Alloy Pear-Shaped HMS Carabiner Series

A high-strength pear-shaped HMS carabiner series designed for outdoor climbing anchor building, emergency Munter Hitch rappelling, rope access, and fire rescue. The entire series is precision-engineered from 7075 aerospace-grade aluminum alloy using hot forging and heat treatment, offering an excellent strength-to-weight ratio and a refined tactile grip.

The series offers two specialized configurations:

1. Angled-Gate Large-Opening Pear-Shaped Screw-Lock (27kN Heavy-Duty Version): Features an innovative angled-gate geometry with an opening width of up to 24mm, significantly increasing operational space when clipping thick-diameter ropes, thick branches, or multiple pieces of hardware. The threaded sleeve features deep-cut anti-slip knurling and is equipped with a "Red Alert Mark" to make it clear at a glance whether the gate is locked. Every unit undergoes an individual 7kN pre-load tensile test before leaving the factory to ensure zero-defect quality.

2. Mini Pear-Shaped Positioning Version (25kN Lightweight - Screw-Lock / 2-Stage Auto-Lock): Compact and lightweight (98mm long × 64mm wide), with a spacious top curve specifically designed for smooth Munter Hitch operation. The base features a dedicated "Notched Base" that actively guides webbing loops or connectors to stay fixed at the center of the major axis, preventing cross-loading. The locking sleeve features diamond-patterned knurling for responsive handling even when wearing wet or muddy gloves.

The entire series utilizes snag-free Keylock nose technology for smooth operation when clipping or unclipping ropes and hangers. All models fully comply with rigorous certifications including European EN 362 (industrial connectors), EN 12275 (mountaineering carabiners), and the latest Chinese fire safety standard XF494-2023.

Key Features

• Angled-Gate 24mm Extra-Wide Opening (Angled-Gate Model Only): Effectively increases clearance, allowing large-diameter ropes, double ropes, or thick anchor hardware to be clipped quickly with one hand.

• Red Security Indicator: When the screw-lock gate is not fully tightened, a visible red warning coating is exposed, allowing safety officers and partners to verify status from a distance.

• Bottom Positioning Notch (Mini Pear-Shaped Model Only): A geometric positioning groove at the bottom of the carabiner naturally locks the harness loop or lanyard in place, forcing the load to remain on the major (longitudinal) axis.

• Optimized for Munter Hitch (HMS): The wide upper curve of the pear shape provides ample room for the hitch to flip smoothly in both directions, ensuring fluid emergency belaying and rappelling.

• Keylock Snag-Free Nose: The interface between the nose and the gate is smooth and seamless, eliminating the common problem of snagging on webbing or rope sheaths when removing equipment.

• Individual 7kN Factory Pre-Load Test: Each Angled-Gate Large Pear carabiner is individually pre-load tested on a tensile machine before shipment to rule out latent casting micro-cracks.

• Authoritative Triple Safety Certification: Complies with EN 362, EN 12275, and XF494-2023, meeting international standards for high-angle rope work and fire rescue procurement.
