Is this door prehung and ready to install?

Yes. It ships hung in its frame with the slab attached, so it sets into the rough opening as one unit. You still need to shim, level and secure it, and a second person helps on the lift.

Does it fit a standard front door opening?

It is built for a 36-inch-wide by 80-inch-tall door opening, the common US entry size. Measure your rough opening and check the frame dimensions before ordering, since trim and threshold add depth.

Does the steel door need painting?

The brown finish is factory applied, so it can stay as is. Steel doors can be repainted later if you want a different color, but prep the surface and use exterior-grade paint.

Will it rust or dent?

Steel doors resist weather well when the finish stays intact, but chips and scratches can lead to rust if left. They can also dent from hard impacts, unlike fiberglass.

Is glass or a sidelight available?

This model has no glass. If you want light at the entry, look for a glazed steel or fiberglass door or add a separate sidelight.

What is included with the door?

You get the prehung steel slab in its frame. Check the listing for whether hinges, threshold and weatherstripping are included, and plan on buying the lockset and handle separately.
