The No 7953 surface bolt is typically used on the passive leaf of a double door at top and bottom. The architectural rectangular body and ogee-topped backplate provide a classical decorative element. It can be used in conjunction with the No 7951 cremone bolt or a mortise lock on the active leaf. The bolt is available in 8", 12", 18", and 24" lengths. All Nanz plated and patinated finishes are available.
