Our take on the Therma-Tru Grid Entry 68-in 80-in x 6-9/16-in Fiberglass 3/4 Lite Right-hand Inswing Black Painted Prehung Front Door with Sidelights

This is a prehung fiberglass entry door with two sidelights, a 3/4-lite decorative glass panel and a right-hand inswing. The fiberglass slab has an insulating core and resists dents, rot and rust, and the aluminum impact frame comes with weatherstripping and brickmould. It ships painted black and ready for a lockset and deadbolt. The best new price is $2,171.04 at Lowe's as of November 8, 2026, the only new price found.

Questions and answers

Is this door energy efficient?
It has an insulating core and a fiberglass slab, which holds up better than wood against heat and moisture. The impact-rated aluminum frame and weatherstripping help seal the opening.
What does right-hand inswing mean?
The hinges are on the right as you look at the door from outside, and it swings inward. Measure your opening and check the swing before ordering.
Is the door painted or unfinished?
The listing says black painted and also lists the finish as unfinished. Confirm with the seller before buying if a factory finish matters to you.
Does it come with a lockset?
No. It is prepared for a lockset and deadbolt, which you buy separately. The lock case spec is ASSA 2002.
What are the actual dimensions?
The unit measures about 81.5 in high and 37.5 in wide, with a 6-9/16-in jamb depth. The common size is 36-in x 80-in.
Is $2,171.04 a good price?
It is the only new price found as of November 8, 2026, so there is no recent range to compare against. Compare it with other sidelight door units before deciding.
