Features
4-way lockingIn only, out only, fully open or locked — control exactly when your dog comes and goes.
High-swing flapThe flap swings higher than standard designs, reducing stress on the flap and hinge.
Self-lining, no external screwsA clean finished look on both sides of the glass.
Quiet, sealed actionFull brush seal and near-zero flap tolerance keep draughts out — with a light closing action every pet can manage.
Built for Australian sunUV-stabilised, high-impact polycarbonate that won’t yellow, fog or harden.
Easy flap replacementYears from now, a new flap (G-DDRF) brings it back to new in minutes.
Good to know: toughened or double-glazed panels can’t be cut after manufacture — your glazier orders a replacement panel with the 385 mm hole pre-cut, then fits the door. Any glazier can arrange this, or use our installer directory.
Common Questions
Will this door fit my dog?
The flap opening is 270 mm wide × 313 mm high, which suits medium to semi-large breeds. Measure your dog at the widest point (usually the chest) and compare it with the 270 mm flap width, or let our Find Your Fit tool pick the model for you.
Can it go in my sliding glass door?
Yes — it glazes into a round 385 mm hole cut in the glass panel itself, in glass 3–32 mm — single and double glazing.
My glass is toughened — is that a problem?
Toughened glass can’t be cut after manufacture, but the fix is routine: your glazier orders a replacement panel with the hole pre-cut and fits the door into it.
Who installs it?
A glazier does the glass cutting and fitting — use our installer directory or any local glazier. The door itself clamps into the hole with no external screws.
Will it keep the weather out?
Yes — a full brush seal and tight flap tolerance block draughts, and internal drainage angles carry water out of the door body. In truly exposed, gusty positions, pair it with an external deflector and the in-only lock setting.
What happens if the flap wears out years from now?
You replace just the flap, not the door — the G-DDRF replacement flap clips in within minutes and brings the door back to new.
