Is this door prehung and ready to install?

Yes. It ships hung in its frame with the right-hand swing set, so it goes into a prepared rough opening rather than needing a separate frame and hinge work.

What size opening does a 36 by 96 inch door need?

Plan a rough opening a bit larger than the door on each side and at the top to allow for shimming and squaring. The 96-inch height is taller than the common 80-inch door, so check your header height first.

Does the steel and aluminum build rust?

The aluminum frame will not rust like steel or wood, and the steel face is typically finished to resist corrosion. Chips and scratches in the finish should be touched up to keep moisture out.

Can I add glass or a window later?

This model is solid with no glass, and adding a window means cutting the panel, which voids most warranties. If you want light, choose a glazed model in the same line instead.

What does right-hand hang mean?

Standing outside facing the door, the hinges are on the right and it swings inward to the right. Measure your opening and swing clearance before ordering, since this model is not offered in a left-hand version here.
