Most sizes of ALIENS are narrower than other 4-cam units! Patented internal spring construction allows placements where even most 3-cam units won't fit - like in pin scars, pockets and mini-huecos. Flexible single cable permits ALIENS to be slotted deeper and "walk" less than other camming devices. Reach for a SUPER LONG with an additional 3/4" reach - for sinking deeper placements and better security. ALIENS rack well and are famously easy to place. Each CCH cam is tensile tested at the factory and also UIAA tested and approved. Shipped first in first out - place your reservation today! Call for delivery guestimate. New 1.25 size is perfect for knuckle sized cracks!
