The Mull-It-Over Mullion Trim Cap is a simple and clean trim detail for the exposed end of a partition wall that allows for differential movement between the partition and glass systems. Easy to install during new construction or added during retrofit to correct existing sound transfer problems or code violations. Mull-it-Over trims provide up to STC 60, with optional 1 or 2 hour fire rating.
