The Kapron 211 marking snap case is a super durable snap with an Easygrip surface that's comfy to use even for long periods. The hook attached to the line grabs firmly onto nails, edges, and drywall. Thanks to the tight filling compartment, the marking powder doesn't spill out during filling.

Marking devices/snaps are used to mark long straight lines. Attach the line to one end of the line to be marked, then pull the line with the marking device to the other end of the line to be marked. Secure both ends to the ends of the line to be marked, like with a nail. Lift the line into the air and release. When it snaps down, the marking powder stuck to the line transfers to the surface below and creates a straight long line.
