The SUPCO t1121 is a chair-style electrical terminal packaged in a 10-piece service pack. Chair terminals provide a secure mechanical and electrical connection point for wire splicing and equipment wiring tasks. Built from brass, these terminals offer reliable conductivity and corrosion resistance. Rated for up to 600 volts and a maximum temperature of 221 degrees F (105 degrees C), they are suited for a range of low- and line-voltage wiring applications. The 10-piece quantity makes this pack a practical choice for service calls where a small supply of terminals covers the job without overstocking a van or parts bin.
Chair terminal service packs like the t1121 are commonly used by HVAC technicians, electricians, and appliance service professionals. Typical applications include equipment wiring repairs, terminal replacements on motor leads, and general electrical service work in residential and light commercial settings. The small pack size is well-suited for single-job use or topping off a service kit.
Designed as a general-purpose replacement or service terminal for use in electrical wiring repairs on HVAC equipment, appliances, and other systems requiring a chair-style brass terminal rated to 600 volts.
Installation is typically performed by licensed electricians or HVAC technicians. De-energize the circuit and verify zero voltage with a meter before making any terminal connections. Use the correct terminal crimping tool to ensure a secure mechanical connection. Follow applicable NEC requirements for the circuit voltage and wire gauge being serviced.
