Carpenter/Mason Automatic Chalk Pencil NEO tools 13-810

The NEO tools Carpenter/Mason Automatic Chalk Pencil 13-810 is an automatic chalk holder designed for precise marking on wood, masonry and other construction materials.

The tool is compact and designed for one-handed operation and quick chalk replacement to reduce downtime on the job.

Advantages

The automatic feed mechanism provides controlled chalk advancement for uniform marks and reduces frequent manual sharpening or tapping. The pencil-style form factor and balanced weight allow steady handling and accurate lines. Quick-release or simple access to the chalk chamber makes refilling fast and minimizes interruptions during work. The design is intended to withstand typical on-site use and to be compatible with common chalk stick sizes used in construction marking.

How to use

Open the chalk chamber according to the tool's access point, insert a compatible chalk stick and close the housing.
