Cat Flap Double Glazing
Can the existing toughened unit be drilled?
The aperture must be prepared as part of manufacturing the replacement glass before toughening.

Cat Flap Double Glazing — planning the work
For cat flap double glazing, dimensions alone do not define a suitable pane. Glass construction, edge support and the surrounding frame affect the specification and fitting arrangements.

Can I choose the flap after the unit is ordered?
