Beautifully designed buildings deserve the finest details. Unfortunately, multi-story buildings with concrete decks are prone to deflection caused by loading and concrete sag. This deflection results in unsightly cracks along the inside corners where the walls meet the ceiling. The company’s Ceiling Mounted Deflection Bead is mounted to the roof deck and has a 1-inch leg that hangs down to cover the up to a 3/4 inch gap, left between the drywall and the concrete deck. Since it is only attached to the deck, the bead slides up and down on the wall. It leaves a sharp crisp shadow line along the length of the wall. The product is a permanent fix to deflection reducing your building maintenance costs.
