The MARSHALLTOWN Leaf Point Line Pins help stretch mason’s line while laying a brick or block course. The leaf point design allows you to place the Line Pins easily into mortar joints or stake them into the ground. They feature a large circular head for a wide striking surface. The Line Pins are chrome-plated to prevent rust and wear, and they are forged into a single piece of hardened steel to prevent bending, cracking, and breaking.
