A corbel is a large, usually ornate, wall bracket used to support the ceiling, a shelf, molding, or another architectural feature. These large but lovely design features have recently become very coveted for architectural salvage projects.
Are corbels necessary?
Do you need them for support, want them for a specific aesthetic, or both? While corbels are functional in that they support your countertop they can also be used as a design element. You may simply want corbels to adorn your home, but keep in mind that their main purpose is utility.
Where should corbels be placed?
POSITIONING THE CORBELS UNDER A COUNTERTOP OR SHELF
To position the corbels under the shelf or counter top, place one corbel three to six inches in from each end, unless the counter or shelf meets a wall. In this case you should install the end corbel(s) against the wall.
