What does prehung mean here?

The steel slab comes already hung in its frame with the hang side set to R (right). That saves fitting hinges and squaring the door on site.

Will a 50-inch door fit my opening?

A 50-inch door needs a rough opening wider than 50 inches to allow for the frame and shimming. Measure the framed opening before ordering, not the old door.

Does the black enamel finish need maintenance?

Steel with an enamel coat needs little upkeep, but touch up chips promptly. Bare spots left exposed can rust, especially near the bottom and hardware.

Is a steel door good for a front entrance?

Yes. Steel is strong, holds its shape and takes less upkeep than wood. The trade-off is weight and a colder, more industrial feel than solid wood.

Is this door a good buy?

It is the only new listing for this model, so there is nothing cheaper to compare it with. Judge it on the 50-inch steel slab and prehung frame rather than on competition between stores.

Can I reverse the hang to the left side?

This unit is built with a right-hand hang, so the hinges sit on the right as you face it from outside. Reversing it means rehanging the slab or ordering a left-hand version.
