The Hole Marker is a precision marking tool designed to help you accurately mark the center point for drilling—especially when used alongside accessories like the joist adapter, double joist adapter, or radiator valve.

Saves time when marking pipework
One of the key features of the adapter is that it’s magnetic. This makes it especially handy for plumbers and electricians—allowing the adapter to be quickly and securely attached to pipework, joists, or an electrical box.

Locate position across room with 3mm tolerance
You can mark an electrical box or any fixture on one side of a room and get an identical position (within a 3mm tolerance) on the opposite wall—perfect for consistent, professional results every time.
