Modular Contractor® Terminal Blocks
Cliff™ modular contractor® terminal blocks are primarily intended for use in permanent installation situations. They are designed as a superior alternative to old style screw terminal barrier strips. They can be used in power supplies, amplifiers, car equipment, shower controls and various touch-proof and tamper-resistant electrical and electronic equipment.
