Why MDF Radius Corners
The Problem This Solves
L Corner — 3″ Radius
The L Corner profile at 3″ radius provides the same complete two-leg corner geometry as the 4L34 in a more compact footprint. The tighter radius suits narrower cabinet runs, desk returns, and full-height built-ins where a 4″ corner would overhang adjacent elements.
Double Refined MDF
Double Refined MDF machines cleanly, paints to a flawless finish, and holds its shape over time. No grain inconsistency, no void risk — just a consistent, dense substrate that takes primer and paint the way cabinetry demands. A surface indistinguishable from solid wood when properly primed and painted.
Only National Manufacturer
White River Hardwoods is the only national manufacturer of MDF radius corners in the USA — made in Fayetteville, AR. Consistent quality, reliable availability, and a supplier that has been delivering to the cabinetry industry nationally for decades.
Accepts 3/4″ Plywood
Engineered specifically for 3/4″ plywood box construction — the standard substrate for this profile. The plywood box butts cleanly into the radius corner without shimming, scribing, or custom fitting. One piece, right the first time.
