Horizontal Closures
To install horizontal closures across the top front surface of the sound-isolation room,
proceed with the following steps:
1. Install closure brackets along the top surface of the wall panel sections at the front of the room.
a. Space the brackets a maximum of 2-feet (610 mm) apart.
b. Position each bracket

" (21 mm) back from the front surface of the room.
c. Attach the brackets to the room using two #8-18 x ¾" self-drilling screws in each bracket.
2. If the closure panel is being mounted flush to the ceiling, attach a 2 x 4" metal stud
to secure the top of the closure panel.
If there is no ceiling directly above the closure panel, a 2 x 4" metal stud frame
must be built to secure the top of the closure panel.
