Where the CTL2.5-5 Crimp Lug Is Used

A compression crimp lug terminates a single conductor end to a bolted connection point — the conductor is inserted into the barrel and a compression crimp tool closes the barrel around the conductor, making a permanent, mechanically secure, low-resistance termination. The tongue of the lug is then bolted to the connection point — a terminal block, earth bar, busbar, equipment stud, or similar — using an M5 bolt through the 5mm stud hole.

The CTL2.5-5 is sized for 2.5mm² conductor — the standard cable size used for power circuits in Australian residential and commercial wiring including ring mains, power points, and general purpose outlets. The 5mm stud hole suits M5 hardware, commonly used on terminal blocks, earth terminal bars, DIN rail terminal connectors, and light duty equipment terminals. 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 at the bolted joint over the service life of the installation.

Crimp lugs in this range are available across a wide range of cable sizes and stud hole combinations — covering the full range of conductor sizes and connection hardware used in Australian electrical installations.

Q: What is the difference between CTL2.5-4 and CTL2.5-5?
A: Both are 2.5mm² tinned copper tube crimp lugs with identical barrel and cable specifications. The only difference is the stud hole — CTL2.5-4 has a 4mm stud hole (suits M4 bolts) and CTL2.5-5 has a 5mm stud hole (suits M5 bolts). Select the correct size to match the bolt or stud at the connection point.

Q: What stud or bolt size suits the CTL2.5-5?
A: The CTL2.5-5 has a 5mm stud hole, suited to M5 bolts and studs — commonly used on terminal blocks, earth terminal bars, and light duty equipment connection points.

Q: Is the CTL2.5-5 sold individually or in a bag?
A: The CTL2.5-5 is sold individually.
