Is this door steel or wood?

The name says prehung steel, but the material field says teak. Ask the seller for the actual slab construction before you buy, since the two imply very different weight, security and maintenance.

The listing shows glass as both yes and no, so the glazing is unclear. Confirm whether the slab is solid or has a lite, and what glass type, with the store.

What does prehung mean for installation?

A prehung door comes mounted in its frame with hinges set, so it drops into a prepared rough opening rather than needing a separate frame and hinge fitting.

Which way does it swing?

It is listed as a right-hand door. Check your opening against that handing before ordering, because reversing a prehung door is not a simple swap.

What size opening does a 48-inch door need?

A 48-inch leaf needs a rough opening wider than the slab to allow for the frame and shimming, typically a few inches more. Have your contractor confirm the rough opening before ordering.

Is this door worth it against similar doors?

Only one store lists it new, so there is no competing price to benchmark against. Compare its construction, glazing and handing with similar prehung exterior doors before committing.
