17-48 Melfield Gardens

The espagnolette has adjustable mushroom bolts, locking into the keeps securing the window against forced access.

Mushroom bolts may be adjusted from time to time to increase or reduce the pressure on the seals.

The keep is fitted with both front screws and slanted screws into the frame, which im proves the window’s strength against in truders.

The keep has two slots, the inner slot is for closing the window, while the outer slot produces a gap at the bottom of 10-20 mm for a night ventilation facility which can be securely locked in position.
