Nails

Cable clip nails are hardened, and usually go into masonry. If getting them in proves impossible, its worth trying the vertical mortar joints rather than horizontal. The other option is pin plugs. These are little wallplugs designed for pins. Or any type of resin glue can go into masonry holes instead, and the cable clips whacked in once set.

Spacing

Consistent spacing looks much neater than spacing estimated by eye. The quickest way is to cut a piece of card to the fit the gap between clips.

Maximum permitted distance between cable fixings:

  • PVC cable upto 9mm dia: horizontal 25cm, vertical 40cm
  • PVC cable 10-15mm dia: horizontal 30cm, vertical 40cm
  • PVC cable 16-20mm dia: horizontal 35cm, vertical 45cm
  • PVC cable 21-40mm dia: horizontal 40cm, vertical 55cm
  • MICC upto 9mm dia: horizontal 60cm, vertical 80cm
  • MICC 10-15mm dia: horizontal 90cm, vertical 1.2m
  • MICC 16-20mm dia: horizontal 1.5m, vertical 2m
  • For flat cables, the widest dimension is regarded as the diameter

Shapes

Standard cable clips come in flat and round varieties. There are slight differences in proportions between T&E, twin and 3&E clips.

Colours

As well as white & grey clips, red & orange are also used with fire alarm cable.

Much like a standard plastic cable clip, but fixes 2 cables and has 2 nails, one on each side of the cables. Not popular.
