The STANLEY® FATMAX® Chalk Line rewinds 3x faster due to its 3:1 gear ratio. Not only does it have a water-resistant, high-impact ABS case with rubber grips that make it comfortable to hold, but there is also a stainless-steel end hook for added durability and rust prevention. Its large 45g chalk well helps to reduce refilling times, while the chalk view window also allows you to see exactly how much chalk you have left. The high-grade Blue Chalk Refill is packaged in a square bottle which is designed to not roll off work surfaces. Plus, the bottle features an easy-pouring, twist-to-open spout! Ideal for electricians, plumber, and general contractors, the ink in the Fine Tip Black Marker is quick drying and ideal for avoiding smudged lines. It can be used for marking copper roofing material, gas pipe, black pipe, wood, and metal and marking tools and equipment. Suitable for colouring nuts and bolts that need to be black!
