Where the RCL4 Crimp Link Is Used

A compression crimp link joins two conductor ends together — the conductors are inserted from each end of the link body and a compression crimp tool closes the barrel around both conductors, making a permanent, mechanically secure, low-resistance electrical joint. The crimp link is the correct method for extending a conductor run, jointing cables in a junction box or enclosure, or connecting two cable ends where a screw terminal or connector block is not appropriate or practical.

The RCL4 is sized for 4mm² conductor — the cable size used for higher-current circuits in Australian residential and commercial wiring including air conditioning circuits, stove and oven sub-circuits, and other dedicated appliance circuits where 2.5mm² conductors are insufficient. The tinned copper construction combines the excellent conductivity of annealed copper with a tin electroplated surface that resists oxidation and maintains a clean, low-resistance contact surface over the life of the joint. The single crimp is applied with a K25 crimping die using a standard compression crimp tool.

Crimp links in the RCL range are available in sizes from 1.5mm² through to 70mm² — covering the full range of common cable conductor sizes used in Australian electrical installations.

Q: What is the difference between a crimp link and a crimp lug?
A: A crimp link (RCL4) joins two conductor ends together — it has an open barrel at both ends, one for each conductor. A crimp lug terminates a single conductor to a bolted connection point — it has one barrel end and one lug or ring end. Use a crimp link for conductor-to-conductor joints; use a crimp lug for conductor-to-terminal connections.

Q: What crimping tool and die is required for the RCL4?
A: The RCL4 requires a K25 crimping die with a standard compression crimp tool. Confirm your crimp tool is rated for 4mm² copper conductors before use.

Q: Is the RCL4 sold individually or in a bag?
A: The RCL4 is sold individually.
