MASTER AL Lock is state of the art full-body harness with a revolutionary waist adjustment system. The waist belt is composed of three pieces, which allows you to purchase one standard size and then customize the sizing to your exact fit requirements. User can move the AL positioning points exactly according to his needs. The harness is also comfortable thanks to the reinforced padded waist belt and leg straps.
