The 12' (3,65 m) Craftsman® Self-Lock tape measure features blades that automatically stay in a locked position until you press a button to retract them. The blade can be locked for extra tension or unlocked for smooth, controlled retraction. The fractions are printed on the blade for quick and easy measurements. The tape is protected by a lacquer coating to prevent blade damage and increased durability. A rubber over mould ensures added grip.
