DMM Shadow HMS Locksafe Carabiner (A687)

Description

The DMM Shadow HMS Locksafe Carabiner (A687) is a lightweight, high-strength HMS connector built for belaying, rigging, and general climbing systems. It is designed for arborists, climbers, and rope access professionals who need a reliable locking carabiner with smooth handling and strong performance.

First, the carabiner uses a true HMS shape, which provides a wide internal basket for ropes, hitches, and belay devices. This improves rope flow and reduces crowding in anchors and belay setups. As a result, handling stays clean and efficient in technical systems.

Next, the hot-forged I-beam construction reduces weight while maintaining strength. The carabiner achieves a 26 kN major axis rating, giving it strong safety performance for professional use. At the same time, it stays lightweight at around 76–77 g, which helps reduce rack weight over long climbs.

In addition, the Locksafe triple-action gate system increases security. It requires three deliberate actions to open, which significantly reduces accidental gate openings. Therefore, it performs well in high-consequence environments where safety is critical.

Furthermore, the keylock nose design eliminates snagging on ropes, slings, and bolts. This allows smoother clipping and unclipping, especially in tight or cluttered rigging systems.

The carabiner also features reinforced contact zones for improved abrasion resistance. This extends service life under repeated use and harsh conditions, making it suitable for daily professional work.

Although compact, the Shadow HMS Locksafe still provides a generous internal basket capable of handling multiple clove hitches and belay configurations. This balance of size, strength, and usability makes it a versatile choice across climbing disciplines.

Overall, the DMM Shadow HMS Locksafe delivers lightweight efficiency, high safety, and dependable handling in a proven HMS design.
