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.
Trigger Wire
Description
Here, a specialized "trigger" holds the gate open until the slightest pressure is applied(as when a rope is dumped into the open gate). Also available in a quickdraw set up, the Trigger Wire is an innovative addition to your rack, ideal for desperate clips, use with a stick clip, or as a cheater biner when hanging those draws.

HAIR TRIGGER
Set the eponymous, spring-loaded “trigger” bar to hold the bent-wire gate and voila, you have a wide-open gate, ready to be clipped or stick clipped. (With a little practice, you’ll find it easy to set the trigger one handed.) Like a mousetrap, only the lightest touch on the trigger, which physically occupies almost the entire gate opening, is required to release the gate.
DOUBLE DUTY
The Trigger Wire can be used like any standard biner, too — simply leave the trigger laying flat against the inside of the spine and clip away. The bent-wire gate allows for a generous gate opening and also offers a flat surface that makes clipping easy.
LIGHT MAKES MIGHT
Even with the added trigger hardware, this biner maintains a svelte figure. Meanwhile, the Trigger Wire maintains an ample strength rating (see below).
