Opening-Set for single- and double-offset doorsEvery locksmith knows the problem of closed double-offset doors. The new ACE spiral needles, made of high quality spring steel, allow the non-destructive opening of double-offset doors in most cases. The use is very simple: The tool is inserted in the narrow gap between door and frame by turning until it makes contact with the latch. Continued turning pushes back the latch. Usually this process does not cause any damages except a pierced sealing strip. The set consists of four (4) different tools for doors with the lock mounted either on the right or on the left and 2 different material strengths (1.5 and 1.7 mm) for the different types of offset door designs. Of course, the ACE-tools are very well suited for opening simple offset doors as well!For very tightly engaging (closing) double and simple offset doors the ACE-Mini-Set (2 pieces) of only 1.25 mm needle-strength is especially suited.
