Gemini double door locking system

The Gemini system makes composite or timber double doors simple. With both master and slave lock either mounted on hard wearing aluminium extrusions or directly on to the timber sashes, fitting is simple.

The 3 deadbolt master lock interlocks with the slave, locking the top and bottom shootbolts in place. Gemini has achieved both PAS23/24 and Secured by Design approval.

Suitable for both 44mm and 56mm door widths, Gemini is available in a range of hardwearing finishes. When matched with the Fullex ABC anti snap and bump cylinder system, Gemini is at the forefront of residential double door security.
