KONG HEAVY DUTY ALU SCREW SLEEVE | High-Strength Aluminum Locking Carabiner
The KONG HEAVY DUTY ALU SCREW SLEEVE is a high-strength aluminum locking carabiner designed for professional rope access, technical rescue, fall protection, and demanding work-at-height applications. Featuring an impressive 36 kN major-axis strength, it is KONG's strongest aluminum carabiner in its connector range.
Constructed from high-tensile aluminum alloy, the HEAVY DUTY ALU features an asymmetric D-shaped body that helps prevent connector rotation and directs loads along the stronger major axis. This design provides reliable performance in demanding rigging, anchoring, and rope-based operations.
The manual screw-lock sleeve provides a secure locking connection, while the integrated Keylock system eliminates the traditional snagging tooth at the gate and nose. This smooth design helps prevent ropes, webbing, and attachment points from catching during connection and removal.
With a compact design weighing just 88 grams, the HEAVY DUTY ALU combines exceptional strength with lightweight construction. Each connector is individually tested and manufactured in Italy.
