SMC - Spider Descender

The SMC Spider is an Auto Braking NFPA “L” Rated Descender designed for work positioning and personal descent on rope diameters of 11mm to 12.5mm. The Spider provides the ability to easily maneuver and secure oneself while working at height, maintaining full control at all times while also having an excellent “feel” when on rope. This allows users to easily load and unload from the device without having to unclip from their harness, making it an ideal descender for window washers, fire fighters and industrial workers who need a device that provides them with optimal strength and performance. A lever-activated cam allows the user to control the rate of descent, and releasing the lever at any time will automatically lock the device to bring the user to a full stop.
