From the maker · Steves & Sons’s description

Durable fiberglass exterior door slab from the Reliant Series, primed white and ready to paint. Features clear Low-E 9‑lite glass and an integrated extra‑large pet door for pets up to 120 lb, ideal for replacing an existing slab opening.

Classic Cottage Charm with Pet‑Friendly Ease

This door invites sunlight to dance through its crisp 9‑lite grid, giving your entry a timeless, tailored presence. I love the seamless integration of the extra‑large pet door—it’s practical luxury for modern living. Paint it a soft sage or inky black to punctuate your facade and let the clear glass visually expand the threshold. A refined essential that balances everyday function with elevated curb appeal.

Guide

What to measure before ordering

These notes are a planning aid. Product names, photos and shared descriptions do not confirm fit. Check the selected SKU, manufacturer specifications and installer measurements before ordering.

  1. 1

    Identify what you are replacing.

    A slab is the door panel. A prehung unit includes a frame. Record whether you need a slab or a complete unit, and check exactly what the selected product includes.

  2. 2

    Measure the opening and the frame.

    Record the width and height in several places, plus the wall or jamb depth. Keep rough-opening measurements separate from the existing door's dimensions. Include the units with every measurement.

  3. 3

    Confirm the swing and the exact model.

    Note which side the hinges sit on, the side you are viewing from, and whether the door swings toward or away from you. Confirm handing terminology and required clearances against the manufacturer's documentation for the selected SKU.
