Mechanisms for tilt-turn windows

Only a few, simple operations, a wide adjustment range makes for hassle-free fitting, high quality materials and full operating safety

« Back to mechanism for tilt/turn windows

Wear-and-tear resistant and long life thanks to fully stainless steel construction. Other sturdy construc-tion features include ratchet positioning in proximity to the hinge to reduce clearance and reinforce the closing mechanism itself and stren-gthen the clutch device that prevents the casement from being thrown open or slammed shut by a gust of wind.

This special safety device prevents improper accidental operations that may risk damaging the mechanism or injuring the user.

Improves hopper window operations preventing casement over-projection while at the same time effectively burglar-proofing when casement is ajar.

Permits standard casement opening only with the key without restricting the hopper opening mode.

Striker and ratchetImproves casement seal and burglar-proofing. Consists of a hooked striker for securing to the frame and a mushroom ratchet for fitting to the rod.

Key-operated cremone boltThe ASTRA casement turn-and-tilt system may be mounted with the key-operated OPERA VIP cremone bolt (see). The latter permits handle locking in several opening and closing positions.

The ASTRA casement turn-and-tilt system may be mounted with the OPERA VIP cremone bolt with detachable handle.

The configuration is especially suited to such public venues as schools, hospitals and nursing homes, to name but a few, where for safety reasons OPENING of the window needs to be RESTRICTED to authorised personnel only.

An adjustment dowel located on the bottom hinge support permits -05 mm to + 1.5 mm adjustments with respect to daylight aperture dimensions
Adjustments are made by acting on the PERIMETER ratchets up to 1.5 mm with respect to daylight aperture dimensions
An adjustment screw on the arm permits SIDEWAY drop adjustment

ASTRA is set up for fitting with additional top, bottom, and side latches. The advantage is that additional latches may be fitted even after mounting by simply drilling 8-mm holes and securing the adjustable ratchets up to the desired number. Lock points may be 4, 6 (4+2), 8 (4+4).
