1. INSPECT ALL CRATES FOR DAMAGE IMMEDIATELY UPON ARRIVAL. Carefully check for any concealed damage. If glass or frame is damaged, take photos and notes and immediately contact Terra. WARNING: Read separate instructions for unpacking glass before opening crate with glass. Any glass or frame damage must be recorded and reported to Terra immediately.
2. Rough Opening: Rough opening size may be 1/4″ to 1″ greater than overall dimensions of frame (1/8″-1/2″ gap on each side). Ensure the rough opening is dry, clean, and free of any loose debris. Check the opening for plumb and level. Confirm frame will fit in the rough opening.
3. Install frame into rough opening a. Unpack frame from crate b. Place the frame into the rough opening with the “Clean” side of the window mounted flush against the drywall of the “Clean” side of the wall. c. To center the frame in the rough opening, sandwich fire-resistant shims between the outer trim and the window frame. Horse-shoe opening of shims should face the “clean” side aka “flush-mount” side. d. Install 4 trim pieces around perimeter of the window frame. The flat portion of the shim should be touching the rough opening of the wall, with the bend facing the flush mount side aka fire- side. The shims should be stacked between the window frame and the trim. See green highlighted trim in below screenshot, and below photos for reference.
e. Measure to make sure frame is level and straight.

Place 4″x4″ blocks underneath on one side to tilt back and prevent the glass from falling forward/out. WARNING: To safely uncrate glass, see separate glass handling instructions included with glass.
5. Before installing Glass: a. Remove glazing beads from the frame. b. Check that the white glazing tape is installed on both the frame and 4 glazing beads, and that the tape is not damaged. Replace any sections of damaged glazing tape.
c. To properly support the glass, use the supplied setting blocks at quarter points of daylight opening. Setting blocks must rest flush on the frame. Ensure the setting blocks are centered underneath the glazing. The glazing should not overhang.
