Folding Openers

Folding Openers

Folding openers are used to positively lock a window in a closed or open position with a specific gap, to deliver safe and secure restricted opening. They are gravity dependent, so they’re best suited to top hung windows. However, they may also be fitted to bottom hung, fully reversible and pivot windows as long as the units are not installed on an angle (e.g. sloping roof windows).

Choose from our extensive range of Caldwell and DUOFLEX folding openers to find a system suitable for aluminium, PVC-U, timber, steel and composite windows.
