⚠️ Glazier installation required: The G-DDC 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. Contact us for referrals.

Dogwalk® Glass Fitting · Dual Glaze Dog Door

G-DDC Glass Fitting Dog Door Dual Glaze Clear

The Dogwalk® G-DDC is a glass fitting dog door in clear, manufactured from 100% UV-stabilised high-impact polycarbonate — same material as aircraft windows. Its dual glaze frame accommodates glass from 3mm to 32mm thick, making it suitable for both single and double glazing. The flap is designed to swing higher to reduce stress on the hinge and minimise broken flaps. For slim line single glazing installations, see the G-DDSLC. 3-year manufacturer's warranty. Designed in New Zealand by Pet-Tek International since 1999.

Frequently Asked Questions

What is the difference between G-DDC and G-DDSLC?

Both are clear and share the same 385mm cut-out. The G-DDC is the dual glaze version with a deeper frame accommodating glass up to 32mm, suited to double-glazed units. The G-DDSLC is the slim line version with a lower profile frame, suited to single glazing and sliding doors 4–20mm thick.

What glass thickness does the G-DDC suit?

The G-DDC suits glass from 3mm to 32mm thick, covering standard single glazing and most double-glazed units. For glass thicker than 32mm, please contact us to discuss options.

Can I install the G-DDC into existing double glazing?

Not directly — toughened or sealed double-glazed units cannot be cut after manufacture. A new glass panel with the 385mm hole pre-cut must be ordered and fitted by your glazier as part of the installation. This is standard practice and glaziers do it regularly.

What size dogs does the G-DDC suit?

The G-DDC has a flap opening of 270mm × 313mm, suitable for medium to large dogs. Always measure your dog at the widest point of their shoulders and chest before ordering. Use our Pet Door Selector for a personalised recommendation.

Is the G-DDC available in white or black?

Yes — the G-DDW is the white dual glaze version and the G-DDB is the black version — both with identical specifications.

How much does the G-DDC frame project on each side of the glass?

The G-DDC dual glaze frame projects 12.06mm on the inner face and 22.8mm on the outer face of the glass. The deeper outer projection accommodates the full thickness range of double-glazed units up to 32mm.
