Black Flat Twin & Earth Cable Clip

Twin and earth cable clips are one of those things you get through by the hundreds on any electrical installation job, so it’s worth using ones that actually work. These Unifix black flat twin and earth cable clips are made in the UK and come with hardened extra-length nail pins that drive cleanly into masonry and plasterboard without bending or bouncing back at you. The countersunk pin holder is a small but genuinely useful detail — it distributes load around the nail head and stops the clip from splitting when it’s driven home.

Internal grips hold the cable firmly in place once clipped. That matters more than it sounds — a clip that lets cable shift around looks poor, and on a long cable run you’ll notice it immediately. These hold.

Where Unifix Twin and Earth Cable Clips Get Used

These clips are aimed squarely at domestic and commercial electrical first fix, where flat twin and earth is your go-to cable type. Whether you’re running circuits across a timber stud wall, fixing cable to plasterboard, or chasing a run across brick, the hardened pins handle the variation in substrate without fuss. Black finish makes them the right choice wherever standard white would look out of place — garages, outbuildings, loft spaces and industrial units being the obvious examples.

The three available sizes, 2.5mm, 4.0mm, and 6.0mm, cover the most common flat twin and earth cable gauges used in residential and light commercial work. Buying a box of 1000 means you’re not running to the merchant mid-job, which is a small thing that saves a disproportionate amount of time across a full installation.

Unifix is a recognised UK brand with a solid reputation among electricians. The premium construction here is evident in how the pins perform — no skipping, no misalignment, no cracked clips.
