MTU Instruction
for Armorcast Composite Pit Lids
Note on setting the torque range: On a
drill-driver that has about 20 settings
(positions), set the adjustment to #6. Use
the lower speed range of the drill-driver.
This should amount to approximately 8 in-
lbs of torque. Reference the operating
instructions for your particular drill to
more accurately determine what setting to
use to achieve a torque range of
approximately 8 in-lbs.
Step 3 – Use a hammer to gently tap
anchors into the holes indicated in the

Step 4 – Position the MTU face-up on the
bottom surface of the pit lid. Place 2 #8 x
2” galvanized sheet metal screws through
the mounting holes as shown below, and
guide the screws into the anchors.
