Description: The ZDSCHN-ANZ39 consists of a short cylindrical body, the top of which has an external left hand thread, to take the spherical cap.This cap contains the pull disc to which is attached one end of the short length of the pull cord, the other end of which is attached to the coated friction wire. Within the body is the friction composition contained in a copper capsule. The coated friction wire passes through this composition. The copper capsule is retained in the body of an internal shoulder and retaining disk. Above the retaining disc is a retaining collar, held in place by the closing end of the igniter body, forming an internal rim. At it's base, the igniter body is reduced in diameter and threaded externally. When not in use, a brass transit cap is fitted to the base to protect the friction composition.

Operation: The spherical cap is unscrewed and the friction wire is pulled through the friction composition by means of the pull disc and cord to ignite the friction composition.

Employment: This igniter is primarily used for the ignition of safety fuze in demolition work. Also, it is to ignite smoke candles, to booby trap Tellermines and grenades, and to set off improvised mines and booby traps.

Fuze bodies are known in zinc and aluminium.
