Features of Black diamond Rock Lock

Product description of Black Diamond Rock Lock snap hook

Description summary

The Black Diamond RockLock is your essential, versatile screwgate carabiner, engineered for any climbing scenario. Its hot-forged, lightweight design enhances comfort on your harness, while the redesigned spine ensures intuitive handling. Enjoy a larger gate opening for effortless clipping and rappelling, and a durable rope-bearing surface for extended life. The snag-free keylock nose and single-hand operable screwgate provide ultimate security and ease of use. As a Type H/HMS connector, it’s perfect for dynamic belaying and secure anchor setups, making it the trusted workhorse for climbers

Black Diamond RockLock Screwgate Carabiner

As our largest belay and rappel locker, the Black Diamond RockLock carabiner is an indispensable and versatile tool for climbers of all levels. Engineered to be the workhorse of your climbing rack, this carabiner provides uncompromising security and smooth handling for everything from single-pitch sport routes to long multi-pitch adventures. The RockLock is the go-to screwgate for everyday climbing, delivering reliable performance season after season.

Meticulously redesigned for the modern climber, the RockLock now features a hot-forged lightweight construction. This advanced manufacturing process allows for a significant reduction in weight without sacrificing an ounce of strength, making it easier to carry on your harness and reducing overall rack weight. The spine has been re-engineered for better, more intuitive handling, offering a confident grip when clipping and unclipping. Its slightly curved shape maximizes the gate opening, providing ample space for ropes, slings, and belay devices, ensuring fluid and efficient operation when you need it most.

Durability is at the core of the RockLock´s design. A larger rope-bearing surface has been integrated to increase the carabiner´s lifespan and be gentler on your climbing rope by distributing friction and wear more effectively. The classic and reliable screwgate sleeve is easily operable with a single hand, a critical feature for maintaining safety and control while managing the rope. One of the most valued features is the keylock nose, which prevents the carabiner from snagging on your harness, ropes, or bolt hangers, allowing for clean, frustration-free clipping and unclipping every time.

The RockLock is designed for ultimate versatility. Its distinctive pear-shape classifies it as a Type H or HMS connector, making it perfectly compatible for dynamic belaying using a Munter Hitch or with a wide range of modern belay devices. Furthermore, the square hinge end is specifically designed to hold your belay loop securely in place, helping to prevent dangerous cross-loading and ensuring the carabiner remains in its optimal orientation for maximum strength and safety. Whether you are setting up an anchor, rappelling, or belaying your partner, the RockLock provides the security, durability, and user-friendly performance that climbers have trusted for years.

Features:

* Hot-Forged for lighter-weight construction
* Square hinge end holds belay loop securely in place
* Slightly curved spine maximizes gate opening
* Keylock nose prevents snagging
* One-hand operable
* Screwgate sleeve
* Type H or HMS connector. For dynamic belaying using a Munter Hitch or belay device

A good carabiner, great feel

2026/08/28

Raul

It weighs 85 grams but is very strong, the trigger is large and the carabiner eye allows passage even for a knot in dynamic 9 mm ropes, it´s large and of a very adequate thickness, it holds a lot and the shape prevents it from moving or rotating in anchors. I use it for canyoning and when I have gear, it doesn´t turn or move. The screwgate is very functional, it closes and opens well and is easy to handle, but for large hands
