3. Your site measure: We’ll confirm the measurements and bring samples, stain colours, screen door samples and frame upgrade samples to help you choose.
4. Start your order: After the site measure, the next deposit is due so we can get your order underway.

Corinthian Backdoor No. 7 – Supplied & Installed
A practical Corinthian external backdoor, supplied and professionally fitted. Choose your door size and specification, installation option and finish.
Installation options
- Fit new door into existing frame: the new door is fitted into your existing suitable frame. A new frame is not included.
- Supply and fit new door and frame: includes supply and installation of the new door, a new frame and architraves.
Suitability of the opening and any existing frame must be confirmed before ordering.
Raw or Painted
- Raw: doors are supplied as received from the manufacturer, without additional preparation or painting by Just Doors QLD. The manufacturer's finish is shown in the selected door specification.
- Painted: for existing-frame installations, painting covers the new door only; the existing frame is not painted. For new-frame installations, painting covers both the new door and the new frame.
Choose a paint colour to suit your home. We can paint in your preferred colour; please provide your colour selection when ordering.
Handles & Locks
Handles and locks are not included in the listed package price. Choose from our range of handles and locks for us to fit, or supply your own suitable hardware for fitting. Please confirm your hardware selection with us before installation so we can check compatibility and include any applicable costs in your quote.
Optional extras
Weather seals and an Eco frame upgrade are available at extra cost. A Crimsafe security screen is also available. Contact us to include these options in your written quote.
Door specifications
Honeycomb and solid MDF primed constructions, with clear or translucent glazing, are available in the listed model-specific size combinations. Select the exact size, construction and glazing required. Not every combination is available. Dimensions are nominal.
Opening protection
This external door requires a weather-protected opening. Follow Corinthian’s current model-specific finishing, care and installation instructions.
