Dog Doors in Glass – Supply Only
Specialist Dog Flaps for Single and Double-Glazed Glass Panels
At Master Plastics SW Ltd, we supply a dedicated range of dog doors explicitly designed for glass, including single-glazed, toughened, and double-glazed panels. These flaps are ideal for anyone replacing a glass unit or ordering a new panel with a pre-cut hole through a glazier.
It is best practice to ensure there is at least 100mm around the hole cut in the door.

Important Glass Fitting Information
These models are designed for use in glass, but they will also work on wood or panels less than 32mm thick. Installation requires a new glass panel with a factory-cut hole. These dog doors are not suitable for retrofitting into existing units with toughened or sealed glass.
A qualified glazier must carry out professional installations. Is professional installation required?
