Centre Ventilation Key lock - Optional

This multi point key lock is fitted to the centre meeting stiles.

Features:

Secure: The lock self latches as the sliding sash is closed. But for added
security turn the key and lock the window into the external meeting stile
and throw a shoot bolt into head keeper.

Ventilation: The lock throws a shoot bolt into the head (as shown lower left) in the
locked and two partly open positions (50 and 100mm) for secure ventilation.


Centre Latch - Standard
Windows fitted with centre lock meeting stiles can be supplied with this non-key latch (illustrated top left).

Features:

Smooth Operation
Sliding sashes run on large diameter wheels to ensure smooth operation for years to come.

Heavy sashes including double glazed are supported on nylon tyred ball bearing wheels.

The wheel carriage allows sash height adjustment.
