The UIAA equipment standard provides a baseline for equipment performance in a test lab under controlled conditions on new equipment. Although these test conditions are relevant to the conditions encountered climbing, conditions encountered at the crags and the condition of the equipment are equally important. This recommendation from the UIAA member federation The British Mountaineering Council (BMC) provides vital equipment information that is NOT explicitly addressed in the standard, particularly failure modes of the equipment and recommendations for the use, inspection, maintenance, and retirement of equipment.
Hotwire
Description
The wiregate carabiner that started it all, the new updated HotWire is our ultra-versatile carabiner that employs a hot-forged design for lighter-weight construction and a larger rope-bearing surface for greater durability on both the carabiner and your rope.
The biner that started the wiregate revolution, the new and improved Black Diamond HotWire carabiner is an integral part of any climber's rack, due to its versatility. Equally at home on either end of a quickdraw, racking cams or on alpine slings, the HotWire excels as a multi-use wire gate carabiner. With updated geometry and a hot-forged construction—allowing us to remove weight where it’s not needed and add material where durability is key—the updated HotWire has a deeper basket for better clipping, while the hinge-end basket is flatter to hold the webbing of quickdraws more securely. A larger rope bearing surface adds durability not only for the carabiner, but for your rope as well. We’ve also optimized the nose geometry to allow for efficient rope clipping and clipping and unclipping from bolts. The HotWire is a modern classic and ideal for everything from after-work sport cragging to big-wall free climbing and long alpine ice routes.

The Black Diamond Hotwire has been redesigned and reengineered with a different geometry in the spine meant to increase space within the basket while reducing wear on your rope and the carabiner itself. The design seems to work, but other attributes of the 'biner, such as its heavy weight and stiff gate, bump it down a bit on the list of our favorite carabiners. While it's a pretty decent product, we also feel like there are better options in the full-sized market.
