Quick Take
Black fiberglass entry doors can look very similar from across the street, but the real decision between these four is how much of the entrance unit you need. Two are pre-drilled door slabs, one arrives with a 4-9/16-inch jamb, and one includes brickmould with Low-E dual-pane glass. All four share a black fiberglass surface, a polyurethane core, a swinging single-door design, and a woodgrain finish. Door lock accessories are not included with any of the four.

Decision Matrix
- Need a left-hand inswing slab with pre-drilled hinge and lock prep: choose the COMFLAND left-hand slab.
- Need a right-hand inswing slab with the same pre-drilled setup: choose the COMFLAND right-hand slab.
- Need a left-hand inswing entry that already includes a 4-9/16-inch white jamb: choose the COMFLAND KD Door with Jamb.
- Need a left-hand inswing with brickmould and Low-E dual-pane glass: choose the 36x80 Woodgrain KD Door with Brickmould.
All four use the same core construction and opening size, so the practical difference comes down to handing, included frame parts, and glass type.
Product Notes
36"x80" Black Fiberglass Exterior Door Slab LH Inswing Pre-Cut Hinge & Lock
COMFLAND's left-hand slab gives you a pre-drilled fiberglass door with hinge mortises and lockset holes already in place. The fiberglass surface resists dents and scratches, which lowers the upkeep compared with a plain wood door. This is the smallest-scope option in the group because it is a slab only: the frame and casing are separate items in your project. If you already have the frame and are replacing just the door leaf, this left-hand version is the lowest-priced starting point alongside its right-hand twin.
36"x80" Black Fiberglass Exterior Door Slab RH Inswing Pre-Cut Hinge & Lock
This right-hand slab is the mirror image of the left version. It uses the same COMFLAND construction and the same pre-drilled hinge and lockset preparation. The only meaningful difference is handing: choose it when the opening requires a right-hand inswing or outswing door. As a slab, it does not come with the frame, casing, or lock hardware. That makes it the matching lower-priced option for right-hand openings where the surrounding door frame is already in place.
COMFLAND 36'' x 80'' Fiberglass Exterior KD Door, 4-9/16" Jamb Front Enntry Door
The KD door widens the scope by including a 4-9/16-inch white jamb. The frosted glass is its most visible difference, letting natural light into the entry while keeping the view obscured. It fits a 38-1/4-inch by 82-1/8-inch rough opening, and the handing is left-hand inswing. This unit costs more than the two slabs but lands at the highest listed price in the group. If you want a more complete entry assembly and are working with a left-hand opening, this is the one that skips the separate jamb purchase.
36x80'' Fiberglass Exterior Front Entry Door, Woodgrain KD Door with Brickmould
The brickmould version focuses on glass and exterior trim. It has dual-pane glass with a Low-E coating on the outer pane and tempered glass on the inner pane, which addresses energy efficiency and safety. The brickmould is already attached, covering the exterior trim edge. This version is also left-hand inswing only, so right-hand projects should look at the RH slab. The price sits between the slabs and the jamb unit. If Low-E glass and attached brickmould are your priorities, this door is the direct match.
Final Recommendation
If you are installing into an existing frame and want the lowest listed price in this set, the left-hand or right-hand COMFLAND slab at USD 595.00 is the direct pick. If your project needs a jamb included, the COMFLAND KD Door with Jamb at USD 649.00 is the complete unit. If brickmould and Low-E dual-pane glass matter more, the 36x80 Woodgrain KD Door at USD 629.99 splits the difference. Confirm handing before you order, and plan to add your own lock hardware to whichever door you choose.
