The CR/BW and CR/BV types are backstop clutches manufactured by Cross-Morse. These instruments are designed to function for backstop operations. The clutches have been developed to suit conveyor or elevator handshafts, since the structure of the tool is easy to install on new or existing units. These devices are lubricated for life with labyrinth seals suitable for dust laden environment.

These clutches are equipped with a torque arm with slot to employ a fixed bolt to machine frame. Sprags are used to offer a high torque capacity at a cost-effective price. Plain metal brushes with seals that retain grease acts as its bearing support.

It is also provided with ramp principle for extended wear life and rapid application speeds, while its sealing is guarded with labyrinth seals.
