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.

Cam Range (mm / in)
In millimeters and inches, the maximum dimensions of the cam lobes when shut tight and fully extended. Since the "usable" range is so debatable, all manufacturers now list the full dimensions to avoid confusion.
If a manufacturer lists the usable range, we'll include it here as well (this is now very rare).

Summary: Introduced in 1984, Wired Bliss cams began the TCU revolution. They still hold a respectable position near the top of the heap, featuring long stems that make plugging the cams into the back of flared corners a cinch, great spring action, and outstanding durability. Plus, the trigger cables are protected by rubber tubing. I carried a Wired Bliss TCU on my rack for six years until someone stole it, and it's probably still going strong. The only real drawback to Wired Bliss units are their lack of cam stops.
Pros: Long stems; ultra-smooth spring action; rubber sheaths protect trigger wires; light.
Cons: No cam stops.
