CAS Single Conductor Blocks

The block wheels are made of aluminum alloy mounted on ball bearings; the groove is lined by a neoprene ring or by wear-proof interchangeable nylatron or aluminum sectors. The frame is made of galvanized steel. The blocks can be supplied with three types of connections: fixed (B and B1), swivel-type (C and C1) or with a hook supplied with safety lock (D and D1).

Grounding device or complete conductive sheaves are available upon request.
