These square discs are attachments for the Zebra range of line marking machines.
Designed for line marking on hard surfaces such as concrete and tarmac, they can be installed either side of the spray nozzle (as pictured) on a Zebra line marker, in order to provide crisp, sharp and clean edges to the lines.
The distance between the two discs can be adjusted in order to set your required line width.
Using these square discs, a Zebra line marker can be used to line mark car parks, industrial floors, hard sports courts & more.
Made from metal, these discs are easy to clean after a line marking job.
If you have previously purchased a Zebra grass line marking machine with round discs, you can replace the round discs with these square discs to use your Zebra machine for line marking on hard surfaces such as concrete and tarmac.
