-- Tabletop Expansion Bracket (No screws included) -- Finally a bracket made specifically for allowing proper seasonal expansion and contraction of solid wood components! Its no secret that solid wood expands and contracts with humidity changes. A 30" wide table can fluctuate in width as much as 1/4"-3/8" each year. Attaching a large wood top to a fixed base without allowing for this movement can be disastrous as cracks and checks can appear very quickly! Fortunately, this bracket allows for proper movement to ensure your furniture lasts year in and year out, without the need to cut complicated slots or holes. Save time and work with these brackets. Use the bracket for attaching a solid wood tabletop to a support base, or any 90 degree connection between two solid wood components. Made from heavy duty 16-gauge zinc plated steel. These are heavy duty and will not bend easily like other cheaper brackets. Contact us for bulk pricing. Screws are NOT included. Bracket measures 1" x 1" on each side. Elongated holes are 3/16" wide and measure 1/2" long.
