Little Giant G110 Chalkline Review
This chalkline from Keson Tool has a rubber grommet that makes refilling easy
This tool saves time when installing shingles or siding over long distances. The system has 110 ft. of heavy poly-cotton line that runs between two separate boxes. The rewind handles are easy to use, but a 1-to-1 ratio makes rewinding tedious. Together the two boxes hold nearly a pound of chalk, making refills few and far between. One of the nicest features of this product is that it has a rubber refill grommet. Just poke the chalk bottle through the grommet and squeeze.
