RockLock

The Beal Be Lock is a large HMS carabiner designed for easy use with double (halves and twins) rope systems. The large surface area provides easy control in all weather. The Be Lock is particularly suitable for HMS belays and double rope manoeuvres, such as capstan or half-capstan.

The Beal Be Safe is a HMS screwlock karabiner that's perfect for use with belay devices as it can accommodate two ropes at once, without the risk of them becoming overlapped in the event of a fall. The reception cradle ensures that the two ropes slide together and does not generate friction on the sides of the carabiner when the rope is braked. This is true whether rappelling or stopping a fall.

The DMM 30kN Boa HMS Keylock is the heavier duty version of the 25kN Boa, it is hot forged from 14mm bar which gives it the 30kN major axis rescue that's required for rescue loads. Its ergonomics ensure that it is still easily operated whilst wearing gloves and the curved basket copes with even the busiest rigging set ups, allowing devices to settle comfortably.

The DMM Ceros is a purpose-built belay karabiner designed to reduce the risk of cross-loading and improve rope handling. Its internal wire gate keeps the karabiner captive on the belay loop, while the horn on the spine prevents assisted braking devices from moving out of position. Lightweight yet incredibly strong, the Ceros features I-Beam construction, a full section top bar, and a snag-free keylock nose. Available in Screwgate, Kwiklock, Locksafe, Durolock, and ANSI-certified options, it’s the ultimate belay connector for climbers who prioritise safety and reliability.

The Mammut Smart HMS 2.0 Screwgate Carabiner offers the same double safety and easy handling as the older version. The screw locking can be operated only when the safety gate is open. Accidental opening is excluded, as well as unintentional twisting of the carabiner in the belay loop of the climbing harness. This prevents dangerous lateral loading. Mammut recommends use of the Smart HMS 2.0 carabiner for the Smart 2.0 belay device.

The OCUN Condor HMS is a large karabiner that responds to the new trends of safety. Equipped with an independent internal wire gate that prevents it from rotating and guards against unwanted release from a belay loop, this karabiner ensures safe belaying and rappelling. The internal gate locks in the right direction and therefore prevents upward release. This means that the belayer can focus their full attention on the climber. The Condor brings a new level of safety into belaying.

The Petzl Attache is a lightweight and compact, pear-shaped karabiner with as screw gate opening. It has multiple uses for belaying, such as connecting a belay system to a harness and belaying with a Munter hitch. It has a H-cross section to reduce weight, as well as the keylock system to avoid the karabiner snagging during manoeuvres.

The Petzl William is a large-capacity aluminium karabiner designed for belaying, abseiling, and anchoring multiple ropes or slings. Its pear-shaped design allows smooth handling and easy connection of multiple items, while the H-shaped cross-section ensures strength without unnecessary weight. Available in 3 locking options, it offers versatility for rope access, climbing, and rescue applications. The Keylock nose prevents snagging, and the Captiv bar keeps the karabiner properly oriented on the harness. Lightweight, robust, and practical, the William is a trusted choice for professional and recreational users alike.
