INSTALLATION
MOUNTING
For each Terra Drum fixture, an in-ground aluminum sleeve of the same length is required
(see page 3 for part codes and page 27 for dimensions). Sleeves feature four
removable 2” rubber knockouts as well as an acrylic pour cover for the upper surface,
which fully protects the internal chamber while surface work is in progress.
IMPORTANT: To achieve a full 6000 lbs (2,721kg) drive-over rating, the sides of
each sleeve must be fully supported on 8” (203mm) concrete. Otherwise the
fixture must be reduced to a walk-over rating of 2000 lbs (907kg).
