Handles

Cockspur Handle
A cockspur handle provides a window with a single point of locking. The cockspur works on the principle of the handle nose moving across a wedge in a closing position to pull the sash of the window tight against the frame.

Espag handle
Espag handles are used to drive multi-point locking mechisms, such as espag bars and shootbolts. The handle has a protruding spindle that locates into the gearbox of the lock. The handle operation then determines the drive path of the spindle and the opening or closing operation of the lock.

TBT Handle
Tilt Before Turn handles are used specifically to operate a TBT style of window. The handle has three key location positions that determine the operation of the opening vent or sash. The first position holds the window closed, the second position holds the window in the tilt only mode and the third position allows the window to turn inwards to 90°.

Restrictors
Restrictors are often fitted to opening vents or sashes to restrict the opening range of a window. These are used inconjuction with a standard friction stay. The restrictor generally stops the window at an initial opening point of 100mm and can then be disengage to allow the vent or sash to open to its maximum.

Trickle Vents
Trickle vents are designed to provide a steady and constant airflow into a room with out the need for a window to be opened.
