Installation Instructions

Ensure the grates are aligned with an equal distance to each sidewall

before tightening the bolts.

Note: Frame Guards if speciﬁed must be installed before the grates, and

prior to the concrete pour.

14.) Install the construction covers to protect the grating and prevent

construction debris from entering the channels.

Concrete Pour

1.) Check the excavation to be sure a minimum of 4" of concrete can be

poured under, and on all sides of the channels.

2.) Check the entire system for proper anchoring, alignment, leveling, and

connections. While the Dead Level

design dramatically reduces the risk of

oating, a poorly anchored system is likely to shift during the pour.

3.) The edge of the trench frame should be set approx. 1/16" below the

surface after the nish troweling. This will ensure the frame remains at or

below grade after the concrete is fully cured.

4.) Concrete must be adequately vibrated as it is placed, to completely ll

all potential voids around the trench system.

Catch Basin Cutouts

1.) Catch basins may ship in two pieces - attach the frame to the basin prior to

making cutouts.

2.) Invert the basin on a at surface and butt the trench section(s) shown on

the installation diagram against the pattern on the basin.

Note: Catch basins will only mate properly with the downstream end of a #5

channel section, or a neutral channel section.
