Why MDF Radius Corners

The Problem This Solves

⌒

Econo Quarter Round — 3″ Radius

The Econo Quarter Round profile at 3″ radius, engineered for 3/4″ plywood. The tighter 3″ radius is the right choice when the wider 4″ profile would overhang adjacent elements or conflict with hardware placement.

▣

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.

Installation

Working With Radius Corners

1

Plan Your Layout

Determine the location and orientation of each radius corner. The piece is 97″ long — cut to your finished height. Mark cut lines accurately before cutting; MDF does not forgive mis-cuts at visible faces.

2

Cut to Height

Cut with a fine-tooth carbide blade — MDF dulls blades quickly. Cut from the finish face to minimize tear-out. Support the full length when cutting to prevent binding and chipping at the cut line.

3

Dry Fit First

The 3/4″ plywood box should seat cleanly into the radius channel. Dry fit before applying any fasteners or adhesive — confirm seating depth and check that the radius face is flush with adjacent cabinet faces.

4

Fasten & Secure

Secure with construction adhesive and finish nails or screws through the cabinet box. Pre-drill to avoid splitting. Set fasteners slightly below the surface — MDF fills cleanly and holds fasteners well when properly pre-drilled.

5

Fill & Prime

Fill all nail holes and seams with lightweight filler. Sand flush when dry. Apply a quality MDF primer before finish coats — MDF is highly absorbent and requires a sealing primer coat for a smooth, paint-ready surface.

6

Finish to Match

Apply your chosen paint in thin, even coats over the primed surface. Two finish coats over primer is standard for a smooth painted cabinet finish. Sand lightly between coats with 220-grit.

Always Prime MDF Before Finishing

MDF is highly absorbent at cut edges and faces. A quality MDF-specific or high-build primer is essential before any finish coat. A properly primed MDF radius corner paints to a finish indistinguishable from solid wood — skipping the primer step results in an uneven surface that requires significant additional work to correct.

Shipping — LTL Freight

Soft Leather. Fits all my cards.
Color: Ingram Brown
I like the feel of the leather and it’s wearing in nicely. Some of the stitching on the inner liner has worn after taking cards in and out. Happy so far with my purchase.

Look nice
Color: Hayes Brown, Color: Hayes Brown
“I recently purchased a Fossil wallet, and I couldn’t be happier with my choice! The leather feels premium and durable, and the stitching is precise, adding to its overall quality. It’s the perfect size to fit in my pocket comfortably while still offering plenty of room for cards, cash, and even coins. I love the sleek and timeless design that matches both casual and formal outfits. Fossil truly delivers on craftsmanship and style. Highly recommended for anyone looking for a reliable and stylish wallet!”

Buy it, will not be sorry
Color: Ingram Brown
Had previously ordered a Dockers Trifold after having two in the past, it fell apart within a couple weeks. This Fossil wallet, on the other hand, is VERY nice. Very happy with my new wallet, worth the extra $15-20

Only wallet I've owned for 40+ years, I expect this 3rd one to last another 20 years
Color: Ingram Brown
This is the second wallet I ever bought after the original wallet given to me by my father wore out. I love the trifold wallet and this one has been perfect for me. It's made of all leather which is key to long life. All my wrangler jeans have a faded outline on the right front pocket where I carry it. It has multiple slips for my many credit cards, grocery reward cards, insurance cards, business cards, driver license and passport card. There are some pockets behind those for my library card (I seldom need it since I know the number by heart) and my America the Beautiful pass which I only need when I visit a national park. The only complaint still remains from the first version and is that the pockets are about 1 mm to skinny on a new wallet. Maybe that's a good thing so everything doesn't fall out when I open it up to use it. I'm highly partial and highly surprised this wallet is still being made. I'm looking forward to buying another one in 20 years.
