G-DDB Glass Fitting Dog Door Dual Glaze Black
The Dogwalk® G-DDB is a glass fitting dog door in black, manufactured from 100% high-impact polycarbonate. Its dual glaze frame accommodates glass from 3mm to 32mm thick, making it suitable for both single and double glazing. The striking black finish suits dark aluminium window frames, black sliding doors and modern architectural glass. The flap is designed to swing higher to reduce stress on the hinge and minimise broken flaps. For the clear or white version, see the G-DDC or G-DDW.

⚠️ Glazier Installation Required: The G-DDB must be installed by a professional glazier. A 385mm diameter round hole is drilled through the glass using specialist equipment. Do not attempt DIY installation — incorrect cutting may crack or shatter the glass. Note that toughened or sealed double-glazed units cannot be cut after manufacture — a new panel with the hole pre-cut must be ordered.
