Door Axis 30 in x 80 in Flush Smooth Hollow Core Composite Interior Door Slab, Primed White

The Door Axis Flush Smooth Hollow Core Composite Interior Door Slab is the cleanest door a modern interior can wear: one uninterrupted smooth face, no panels, no profile. It serves minimalist renovations, apartment turnovers, and paint-grade projects that need an affordable flush slab for an existing frame.

The slab pairs smooth skins with an engineered wood frame and hollow core, holding a flat, true face that composite construction keeps from warping, shrinking, or cracking with the seasons. Most of the range wears a primed hardboard skin ready for paint; the 30 in size is also offered with a stain-grade birch veneer skin for a natural wood look under a clear or stained finish. At about 25 lb in the 30 in size, one installer can transfer hinge mortises from the old slab and hang it in an afternoon. Choose With Lockset Bore for a standard single bore, or Non-Bored to drill on site for nonstandard strike heights or specialty hardware, and seal all six edges after finishing.

Included Components

• Factory single lockset bore on With Lockset Bore variants
• Installation instructions

Installation Notes

• Measure the old slab, not the opening: match width, height, and 1-3/8 in thickness, and order the slab size that matches the existing frame.
• Transfer hinge mortise locations from the old slab with the new slab clamped alongside, then rout or chisel to the same depth.
• Check the bore position against your lockset before ordering; pick Non-Bored when the strike height or backset is nonstandard.
• Maintain about 1/2 in of clearance above the finished floor, more over carpet or thick flooring; heavy trimming voids the warranty.
• Finish both faces and seal all six edges: paint on the primed skin, stain or clear coat on the birch veneer skin, so the core stays dry and the slab stays flat.

Warranty and Support

• Limited manufacturer-backed warranty, confirmed during quote review.
• Support includes slab sizing checks against your existing frame measurements before release.

Frequently Asked Questions

Is a flush slab right for a modern remodel?
Yes. The uninterrupted face reads as a clean plane, pairs with minimal casing or drywall returns, and takes any paint color. The birch veneer option gives the same plane in natural wood.

Can I stain the primed version?
No. The primed hardboard skin is made for paint. For a stained or clear finish, order the Birch Veneer Stain-Grade variant in the 30 in size, or ask for a quote on other veneer sizes.

Should I pick With Lockset Bore or Non-Bored?
With Lockset Bore ships with a standard single bore that fits common locksets. Pick Non-Bored when your existing strike sits at a nonstandard height or backset, or when using specialty hardware.

Will it fit my existing frame?
Measure your current door. This slab is 1-3/8 in thick, 80 in tall, in widths 24 to 36 in. If the old door matches, the new slab hangs in the existing frame after hinge mortising.
