The patent-pending Sawhorse Supports (item number 41427) from Rockler Woodworking and Hardware are steel brackets that slip over sawhorses to allow additional 2×4 support inside the sawhorse for creating a work table, a base for a miter saw, or more. Sawhorse Supports can be attached permanently with screws (included in the package) or nails, or removed after use. A pack of four costs $12.99.
