Our take on the National Door Company ZZ29343L Steel Primed 6-Panel Left Hand In-Swing Exterior Prehung Door, 64"x80"

A prehung exterior entry door with a 36 x 80 inch 24-gauge galvanized steel slab in a traditional six-panel pattern, factory-primed and set in a 4-9/16 inch frame. It is left-hand in-swing, with satin nickel hinges and a 2-1/8 inch deadbolt bore. The steel skin resists dents, warping and weather better than wood, and the primed finish is ready for paint. The best new price is $1,242.42 at Amazon as of November 8, 2026, and only one store lists it new, so there is no recent low to compare against.

Pros
  • 24-gauge galvanized steel resists dents, warping and moisture
  • Prehung in a 4-9/16 inch frame, so it installs as one unit
  • Primed and ready to paint in the color you choose
  • Six-panel traditional look suits most home styles
  • Deadbolt bore and satin nickel hinges already done
Cons
  • Heavy steel slab is hard for one person to hang
  • Left-hand in-swing only, so it will not fit every opening
  • Primed, not finished, so it needs paint before installation
  • Steel dents under hard impact and can feel cold or industrial
  • Only one store lists it new, so price shopping is limited

Questions and answers

What size rough opening does this door need?
Plan for about 38 x 82.25 inches. The unit itself measures 37.5 x 81.75 inches, and the frame is 4-9/16 inches wide.
Is this door left- or right-handed?
It is left-hand in-swing. Standing outside, the hinges are on the left and the door opens into the house.
Does it come painted?
No. It ships primed only, so it needs a topcoat of exterior paint before or right after installation.
Is the deadbolt hole pre-drilled?
Yes. It has a 2-1/8 inch deadbolt bore, but the lock and handle are not included.
Is $1,242.42 a good price?
Only one store lists it new at that price as of November 8, 2026, so there is no recent range to judge it against. Compare it with similar prehung steel doors before buying.
Can I install it myself?
A helper is strongly advised. The steel slab and frame are heavy, and the unit must be plumb and square in the opening.
Where is the National Door Company ZZ29343L Steel Primed 6-Panel Left Hand In-Swing Exterior Prehung Door, 64"x80" cheapest?
At Amazon, for $1,242.42, as of our latest check.
