Karabiners and Connectors

The DMM 12mm Boa is a great steel carabiner with a wide variety of applications. Whether using in a commercial work environment, outdoor adventure parks or outdoor education centres - this is a steel karabiner capable of many jobs. It has all the versatility of its alloy sibling, but has a rated strength of 40kN. It can be used for many applications where a large gate opening or high internal volume are required. The smooth rounded internal form is very useful when rotating the karabiner through attachment eyes, and the basket curves nicely to allow central hanging of loaded components.

The DMM 10mm Oval karabiner is a strong, compact steel connector designed for pulley systems, rope access, and fall arrest setups. Its oval shape ensures centralised loading, smooth pulley operation, and symmetrical performance, making it versatile and efficient in complex rigging systems. Available with Screwgate, Kwiklock, or Locksafe locking options, it combines strength, security, and ease of use. Cold-forged, heat-treated, and zinc plated, the 10mm Oval has been built to withstand demanding use while providing reliability and confidence in the field.

The DMM 10mm Equal D karabiner is a strong, compact connector designed for height safety, belaying, and anchoring. Its D-shaped design directs the load along the spine for maximum strength, while the cold-forged, heat-treated steel construction ensures long-lasting durability. Available in Screwgate, Kwiklock, or Locksafe versions, all zinc plated for corrosion resistance, it features a generous 15mm gate opening for easy attachment. Individually serial-numbered for traceability, the Equal D is a versatile, reliable choice for demanding environments.

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.

The DMM Rhino karabiner is not restricted to assisted locking belay devices: it works brilliantly with standard devices. The full cross section of the top bar means greater wear resistance, and smooth operation in guide mode usage. The horn makes identification by feel on the rear gear loop easier, and the clean nose design provides snag-free loading and unloading of ropes. The big burly top bar is contrasted by our signature I-Beam construction on the non-rope bearing surfaces resulting in a total weight of 72g.

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 Raumer Round Stainless Steel Ring's surface allows for easy insertion of the rope and exerts the minimum damage to the sheath. As the pressure is spread over the full 360°, the wear on the ring is almost non-existent.  Also used to equip improvised abseil stations using cordage and a bolt-chain-carabiner combination.

The DMM Anchor Rings are simple, functional anchor components that work seamlessly with connectors and textile components. They are ideal when a tamper-proof linking component is preferred over opening connectors, such as establishing remote anchor points.

The DMM Zodiac Karabiners are offset D connectors with an incredibly strong 32kN major axis, making them ideal for rescue loads and heavy rigging. The clean nose gate uses DMM's patented Taperlock design and their toughest barrel, giving very strong gate open and side face strengths. Can be used for general use where weight saving and high strength are important.

The ISC Offset D Keylock Karabiner is great for use by arborists, as well as in industrial height safety and rope access.

The Petzl Am'D karabiner is great for most uses and thanks to its D-shape it's one of the strongest and lightest locking carabiners out there. The 'D-shape' has the highest strength-to-weight ratio of all karabiner designs. The shape and size of the AM'D is great for most uses, such as connecting a belay device to your harness or as a connector at the end of a lanyard. The D-shape makes it one of the strongest and lightest locking carabiners Petzl makes.

The Maillon Rapide Delta is a triangular shaped connector with a hand or spanner tightening screw thread for use in mountaineering, caving, rescue and access situations. Comes in steel with a zinc galvanised finish and stainless steel options from 4mm through to 12mm diameters.

The Maillon Rapide Standard is a strong, oval-shaped quick link connector designed for dependable use in rigging, anchoring, and safety systems. Built on the principle of a chain link with a manual screw nut, it offers exceptional security and resistance to accidental opening. Available in galvanised steel, stainless steel, or alloy, it conforms to EN 362 and EN 12275 standards. With PPE-certified options available, the Maillon Rapide Standard is a versatile and trusted choice for both recreational and professional use.

The Maillon Rapide Pear karabiner is a strong, secure connector designed for reliable rigging and load-bearing applications. Its screw-link design offers greater safety than traditional karabiners, while the pear shape provides smoother rope handling and reduced friction. Available in galvanised steel, stainless steel, or alloy, and in a wide range of sizes, it’s a versatile choice for both recreational and professional use. With PPE-certified versions available, the Maillon Rapide Pear is trusted for everything from ropework to fall protection.

The Maillon Rapide Long Opening is a long oval shaped Maillon Rapide, the gate being longer than the standard. Available in galvanised or stainless steel, and in a number of different sizes (see drop down menu). These are ideal for rigging ropes in any situation where they will not be in view during use as they are much less likely than a karabiner to open accidentally. The downside is that they are slightly slower to use than a screw gate karabiner.

The DMM Vault is a strong and secure racking karabiner designed for ice screws and tools. Made from durable, rigid materials, it offers a safer alternative to plastic clippers. A locking option prevents accidental gate opening, while the low-profile nose minimizes snagging.

The ISC Scaffold Hook is a large aluminium double action scaffold hook.

The Petzl Captiv Adjust is a karabiner positioning bar combined with an Adjust rope adjuster. This positioning bar promotes loading of the karabiner on the major axis and helps hold the Adjust rope adjuster in the proper position to reduce the risk of accidental release. It helps keep the lanyard and rope adjuster integrated with the karabiner, reducing the risk of losing them. The Captiv Adjust is compatible with the OK, Am'D, Bm'D and Oxan karabiners.

The Petzl Captivo is a positioning bar for the Vertigo Twist-Lock connector. It secures the connector to the lanyard, promotes loading of the connector on the major axis and limits the risk of it flipping. The Captivo is only compatible with the Vertigo Twist-Lock connector.

The Edelrid HMS Bulletproof Screw FG Eco is an innovative and robust HMS karabiner with steel insert at the apex and an internal spring bar to prevent it from twisting. Ideal for use with EDELRID belay devices.

The DMM Revolver Rig is a connector with an integrated pulley sheave. Featuring a high efficiency roller bearing sheave(s), a threaded removable captive bar and a full strength textile friendly becket. The uniquely profiled spine and captive bar aid in maintaining correct orientation.
