COMFLAND 36"x80" Black Fiberglass Door Slab: LH vs RH Inswing - Which Handing Do You Need?

Both COMFLAND fiberglass door slabs cost the same and share the same black woodgrain look, but the LH and RH inswing versions fit different openings. Here's how to pick the one that matches your door configuration.

Last updated Aug 17, 2026

Choosing an exterior door slab usually comes down to material, color, and size. With the COMFLAND 36"x80" Black Fiberglass Exterior Door Slab, the two versions being compared here share the same black fiberglass look, polyurethane core, swinging closing mechanism, and new single-door design. Both carry the same $595.00 listed price and are pre-cut for hinges and a lock. The decision, then, is about handing: left-hand inswing or right-hand inswing.

Quick Verdict

Pick the LH inswing version if your door is configured for left-hand inswing/outswing. Pick the RH inswing version if it is configured for right-hand inswing/outswing. Color, core, and pre-cut preparation are the same, so your opening dictates the choice.

Product Notes

COMFLAND 36"x80" Black Fiberglass Exterior Door Slab LH Inswing Pre-Cut Hinge & Lock

This left-hand inswing slab is the one to pick when your entry is set up for left-hand operation. The fiberglass surface resists dents and scratches, and the polyurethane core adds rigidity. It arrives pre-drilled with hinge mortises and lockset holes, which is a real installation aid for a slab-only project. Like its RH counterpart, this is a door slab only: frame, casing, and lock accessories are not included. It is rated for residential use, not commercial applications, and the 35-3/4" W x 79" H x 1-3/4" D slab size gives you the actual dimensions to plan around. If your opening needs left-hand inswing, this is the right match.

The right-hand inswing version exists for the same reason: to match an opening that is handed the other way. The slab shares the same fiberglass surface, polyurethane core, black color, frosted glass style, and pre-cut hinge and lock preparation. So the buying decision is not about one door being better than the other; it is about which one aligns with your configuration. If your entry is right-hand inswing, this is the slab that fits without reversing the preparation. The same limitations apply: no frame, casing, or lock hardware included, and the door is intended for residential use rather than commercial traffic.

Final Choice by Use Case

  • For a left-hand inswing opening: Choose the COMFLAND LH Inswing slab. It offers the same construction as the RH version but is prepared for left-hand placement.
  • For a right-hand inswing opening: Choose the COMFLAND RH Inswing slab. It matches the right-hand configuration and avoids having to reverse hinge and lock prep on site.

If you are still measuring, remember this: the two slabs are identical on paper except for handedness. Confirm which side the hinges sit on and which direction the door should swing inward, then pick the matching LH or RH version. The pre-cut hinge and lock holes handle the rest.
