Key Features
Overview
The Klein Tools Blue Chalk Refill, 5-Pound (CHLK5B) refills chalk line reels with ultra-fine blue marking chalk. This is a bulk chalk line refill designed for everyday layout on framing, drywall and concrete. Klein says it can be used with all chalk reels and specifically lists its CHLK30S, CHLK50S, CHLK100S and CHLK150 reels.
Blue is the go-to for general layout. Klein rates it 1 on its permanence scale, the most removable color in the line, and lists it as fade and water resistant so lines do not wash and bleed away in damp conditions. The pigment is ultramarine blue in a calcium carbonate base.
Blue provides contrast on drywall, concrete, stone, wood and plastic, which covers most of what gets snapped on a jobsite. The ultra-fine chalk dispenses evenly from the reel for consistent coverage and vibrant lines.
The fine-tipped nozzle fits into chalk reel openings for a clean refill, and the pop-off top stays attached to the cap so it does not get lost in the dirt and the bottle does not spill in the bag.
The 5 lb (2.3 kg) bottle is the bulk size for crews who snap lines all day. One bottle refills a reel many times over, so it makes sense to keep it in the gang box or on the truck and top off reels as needed.
Who should buy it: framers, drywall hangers and general contractors snapping everyday layout lines, and anyone running a Klein chalk reel who wants refills that match.
Refill Without the Mess
The fine tip goes straight into the fill port, which keeps the chalk in the reel and off the truck seat.
