Cat Flap in a Origin Grey (RAL 7015) Door
Slate Grey (RAL 7015) is Origin's most-specified colour on OB-49 and OB-72 bi-folds — a mid-to-dark grey that reads slightly bluer than Anthracite.
Origin OB-49 and OB-72 bi-folds in Grey RAL 7015 are among the most premium installations we handle. The aluminium frame is never cut — we supply a new toughened glass panel with the cat flap aperture factory-cut, then swap it into your existing frame.
From £400 supply & fit · 3-year workmanship guarantee
Pet-Tek G-SDDW (Round Cat)
Pet-Tek round flaps are designed for glass panels and complement Origin's minimal aluminium aesthetic — square flaps look bulky next to slim aluminium profiles.

How-To GuidesHow to Replace an Old Cat Flap Without Damaging Your Door or Glass
Start by measuring the existing hole, not the old flap. Most standard cat flaps use a 170mm circular cut-out, so a like-for-like swap is straightforward. If the new flap is larger you can enlarge the aperture in uPVC, composite, wood and aluminium — but never in glass, where a new pre-cut toughened panel is the only option.
How-To GuidesCan You Put a Cat Flap in a Sash Window? What's Possible and What Isn't
Yes, but rarely in the moving sash itself. The practical routes are a cat flap in a fixed lower pane where the glazing can be replaced, a purpose-made panel that fills the opening of a raised sash, or — far more commonly — a flap in a nearby door or side panel. Original single-glazed timber sashes can sometimes be reglazed with a pre-cut pane; modern toughened double-glazed sashes need a whole new unit.
