"These clips are multi-use; not just for plumbing. I've been using these recently for tidying cables (electrical and data). In particular for keeping electrical cables away from data cabling. If you use oversized ones the cables slide through smoothly as you are doing an installation."
"Bought these to clip 15mm pipe to wall behind the tiles, didn't encounter any problems. Would have preferred to buy a smaller pack and save a couple of quid as I didn't need this many, but can't fault the product."
