CMC Survivor 8- Micro Descender- Rappel Device

 The Real thing: Key ring size
This very small Figure 8, Micro 8 descender works well with Escape Lines or other small diameter ropes where minimum size and weight are the primary requirements. The rounded edges reduce sharp bends. The large carabiner hole accepts a wide variety of carabiners and helps prevent binding. Machined of 3/8 inch aluminum stock. Hard anodized in a dark gray for those users that require a non-reflective surface.

 The NFPA 1983 (2006) minimum breaking strength is determined by rigging the descent control device in the manner of use, then locking off. For all CMC Rescue descenders, the failure mode was the rope, not the device being tested.

Benefits

• Extremely lightweight and compact for personal escape applications

• Allows a controlled descent

• Wear resistant finish

Features

• UL classified to NFPA 1983 - Escape

• 3 sigma MBS -5,755 lbf. (25.6kN)

• Weighs 1.5 oz (42g)

• Anodized finish for wear resistance.

• NFPA Auxiliary Equipment Performance Requirements

• Escape Use (Ø 9.5 mm)

• Large Hole (dia.) - 1.25 in. (31mm)

• Descent control devices must not show any permanent damage to the device or to the rope at 5 kN (1,124 lbf) and have a 3σ MBS of not less than 13.5 kN (3,034 lbf).

If the descent control device has a passive breaking feature, the device shall not slip more than 25 mm at a force of 1.35 kN (300 lbf.) when tested on the smallest and largest diameter specified by the manufacturer.

REVIEWS:

Here's another goodie I picked up - CMC Rescue's Survivor 8 descender. Far smaller and lighter than my CMI Rescue Figure-8, this micro version is designed for personal emergency escape. Forged from aluminum, it is machined to shape and given a mil-spec hard-anodized finish. In conjunction with a lightweight carabiner and a rigger's belt, a very unobtrusive escape rig can be put together without a massive weight penalty. The figure-8 and a lightweight carabiner can be easily pocketed or stashed in something like a double handcuff case or exam glove pouch on your rigger's belt. I haven't had the opportunity to test it out yet on a descent, but put it on some rope to see how it would function. It is designed for smaller 9mm ropes.
