This Stanley chalk line reel allows you to apply a uniform chalk line up to 100 ft using a long-wearing felt gasket that hugs the line and distributes the chalk coating evenly. Made of a durable, heavy-duty die-cast aluminum body for extra-long life in a blue-gray color, this reel is designed with a plastic and metal universal hook built to endure the rigors of everyday use. This tool can also be used as a plumb bob.
