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 vs Therma-Tru Grid Entry Fiberglass Front Door

Both are Therma-Tru fiberglass prehung entry doors with sidelights, right-hand inswing, black paint and an ASAA 2002 lock case, so the build and hardware are effectively the same. The real split is the slab and the wall: A is a 36-in door with a 3/4-lite decorative glass panel in a 6-9/16-in impact-rated aluminum frame, while B is a narrower 32-in door with a full-lite Crepi glass panel in a 4-9/16-in frame. Buy A for a standard 2x6 wall opening and more privacy at the bottom of the door; buy B for a 2x4 wall and a taller glass look. Owners of Therma-Tru fiberglass doors generally report the finish holds up and the insulating core cuts drafts, and the common complaint is that sidelight glass and trim need careful sealing at install.

• Choose the 68-in Grid Entry if you have a 2x6 wall, want a full 36-in slab, and prefer a 3/4-lite panel that keeps the lower door solid.
• Choose the 64-in Grid Entry if your rough opening is built for a 2x4 wall and you want a full-lite door that lets in more light.
