The Stanley FatMax® Closed Case Long Tape has a 10mm wide stainless steel blade that resists rusting. Its closed case design helps to protect the blade and internal workings and has a non-slip rubber grip. The 3:1 gear ratio provides 3x faster rewind and a steel roller cage protects the case from being cut by the blade during retraction. There is also a corrosion resistant Tru-zero folding end hook for accurate measurements. Available with metric only or both metric and imperial measurements. Ref: UTTK14865
