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.
Mountain D
Description
The SMC Mountain D Series is the result of a brilliant blending of a straight gate with our best selling Locking D frame. The SMC Mountain D is ideally suited for use as the main connector or in backup applications. Got numb fingers or thick mittens or you are otherwise known by your climbing buddies as a "climbing klutz”? We’ve got you covered with this oversized, easy clipping, easy handling, and high strength carabiner. Definitely this carabiner is designed to fit your day-to-day rescue and climbing needs.
As one of the most versatile mid-sized non-locking carabiners on the market you will find that form and function are no compromise as with all other SMC products. Similar to the Locking D and Light D Series Carabiners, SMC has incorporated stainless steel components internally. Without question this is truly one of the best carabiners ever made.
SMC assures that all carabiners are 100% visually and physically inspected. It is SMC’s attention to detail and precision craftsmanship that guarantees you receive the highest level of quality, value and flawless performance insuring your carabiners are amongst the finest you can buy anywhere in the world.
