The UltraTRAK slotted system utilizes a UltraTRAK slotted deflection track in conjunction with the UltraBEAD providing a 1 or 2 HR rated assembly for a ¾” max joint and is UL 2079-Fifth Edition compliant. UltraBEAD creates an easy attachment that is attained with staples through the bead flange. Multiple perforations along the 1-1/8" flange enhance strong compound adhesion and the raised shoulder provides for a flush finish. Rigid vinyl is rust proof, dent resistant and easy to field cut without distorting profile or leaving sharp edges and burrs. Deflection track details must be designed for the specific conditions of a building to accommodate the required deflection and end reactions of the studs. Deflection tracks cannot be used in axial load-bearing stud conditions or above continuous window spandrels.
