[[image:Cable clips 0963-2.jpg|300px]]

===Nails===
[[Cable]] clip [[nail]]s are hardened, and usually go into
[[masonry]]. If getting them in proves impossible, [http://
http://www.cef.co.uk/catalogue/categ...ammerfix-range pin
plugs] may be used. These are little [[wallplug]]s designed for pins.
Or any type of resin [[glue]] can go into masonry [[Drill bit|holes]]
instead.

===Spacing===
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

I would add the comment from Table 4A OSG about the dimension of the
major axis being taken as the diameter for flat cables such as T&E

I wonder if it is worth mentioning that if a clip cannot be hammered into
the horizontal mortar joints they can still often be hammered into the
vertical joints

Does seem to depend a bit on the bricky!
