DMM Rhino Locksafe Carabiner

The DMM Rhino Locksafe is a specialist HMS locking carabiner designed to reduce the risk of cross loading when used with belay devices, rigging devices, rope tools and pulleys. Built for climbers, arborists and rope professionals who demand dependable connector performance, the Rhino Locksafe offers smart loading control, a generous basket and snag-free handling in a robust DMM design.

What sets the DMM Rhino apart is its distinctive horn feature on the spine, which helps prevent connected devices from twisting around the carabiner and cross-loading the gate. Combined with a flat base that helps the carabiner sit correctly in the belay loop, this makes it a superb option for applications where correct orientation and stable loading are critical.

Whether used in rope access, arboriculture, climbing or advanced rigging systems, the DMM Rhino Locksafe is designed to improve safety, efficiency and device control.

Key Features

• HMS-shaped locking carabiner for rope and device compatibility
• Distinctive horn feature helps reduce cross loading
• Flat base encourages correct orientation in the belay loop
• Wide full-radius basket for rope and device friendly use
• Keylock clean nose for snag-free clipping and removal
• Ideal for belay devices, rope controllers, pulleys and rigging tools
• DMM I-Beam construction for strength-to-weight efficiency

Designed to Reduce Cross Loading

The standout feature of the DMM Rhino Locksafe is its pronounced horn at the top of the spine. This helps stop assisted braking devices, pulleys and rope controllers from rotating into poor loading positions, helping maintain more stable, predictable alignment during use.

This makes it especially useful in systems where maintaining correct device orientation is important for both performance and safety.

HMS Shape for Versatility

The HMS (pear-shaped) design provides generous internal space, making the Rhino Locksafe highly versatile for a wide range of rope and connector applications. It allows connected devices to self-centre effectively and provides extra room for larger ropes, multiple components or knot-based systems such as an Italian hitch.

The larger basket shape also makes it easier to handle with gloves, which is especially useful in outdoor and professional working environments.

Snag-Free, Rope-Friendly Handling

The DMM Taperlock keylock nose creates a smooth, snag-free interface when clipping or unclipping ropes, slings and devices. This improves usability and reduces frustration during repetitive gear handling, while the full-radius basket offers a rope and device friendly contact surface.

Strong, Lightweight DMM Construction

The Rhino Locksafe uses DMM’s signature I-Beam construction on the non-rope-bearing surfaces, helping reduce unnecessary weight while maintaining excellent strength and durability where it matters most.

Ideal For

• Belay devices and rope controllers
• Rigging systems and pulleys
• Arborist climbing systems
• Rope access and technical rescue
• Users wanting to reduce cross loading risk
