  Measuring Tape, Fiberglass, 300 Ft.

  This open reel case is easy to read and highly accurate. Two color tape is imprinted on both sides - one side in feet, tenths and hundredths; the other in meters, cm and mm.

This fiberglass measuring tape comes in three sizes: 100 feet (30 m), 200 feet (60 m), and 300 feet (90 m).
