WC-01Gather your tools and materialsGet everything together before you start: a cordless drill with a masonry bit, a spirit level, tape measure, pencil, and a vacuum or dust sheet for tidying up. Check your clock's hanging point (usually a slot or hook on the back) so you know exactly where the fixing needs to sit. Working on brick or block, you'll need a wall plug and screw sized to suit the weight of the clock, not a picture hook.
