Unfinished hardwood baseboard outside corner block in various wood types

Quiet detail, strong line

A small, squared column that turns an outside corner into a pause—clean, certain, and ready for the finish you choose.

Corners that count

The moment a room gathers itself

Defined profile, open finish

Corners expose every mismatch. The EWBB63 Base Outside Corner Block fixes the meeting point with a consistent 1-3/8 inch square face and a measured 6-1/2 inch rise, so baseboards meet without guesswork. Its 1/2 inch groove accepts the run, keeping lines true and shadow breaks intentional.

From cut ends to a considered stop

When trim carries through a home, the smallest profile shift breaks rhythm. This unfinished solid hardwood block gives you a known profile and projection to plan around before a single cut. Paint or stain later—first, set the proportion so walls, doors, and cabinetry read as one thought.

For the rooms under revision

Homeowners, renovators, and finish carpenters aligning baseboards at outside corners with a consistent, unfinished hardwood block.

Where it lives

Seat the EWBB63 at an outside wall corner and fit baseboards into its 1/2 inch groove to create a clean, finished termination.
