What do I check for finish work: sidewall grille / register fit?

Sidewall air devices must match the wall opening, sit flat, cover the cut cleanly, and not expose a crooked duct sleeve or ugly backing.

Stop if

• The wall opening/backing is rough and the grille will not sit clean. Do you want the opening corrected before I install it?

Watch out

• Stop if the wall is finished and the grille will not cover the opening, has no backing, or conflicts with architectural elevation/details.

Check

• Dry-fit the grille before final screws.
• Check level and reveal around all sides.
• Use correct anchors/backing if wall material requires it.
• Do not over-tighten and bow the frame.
• Clean face and wall after install.
