In-Ground Installation
Step 5: Working from the bottom of the assembly, in-
stall eight (8) self-drilling, self-tapping screws (provided)
through the extension collar wall and into the adapter
ring. Two of these screws should be installed in each
of the four (4) skirt areas of the adapter ring. Check
the extension collar height dimension frequently during
this operation to ensure that the collar has not moved.
Note: Use caution when tightening these screws to en-
sure that they do not strip.
Step 6: Place the adapter ring/extension collar assem-
bly onto the Trapzilla unit. Position the small cover onto
the extension collar. Secure the adapter ring and the
small cover with the brass nuts and flat washers provid-
ed. Seal the gap between the 18” extension collar and
extension collar adapter ring using a silicone sealant.
Step 3: Remove the extension collar from the adapter
ring and, with an appropriate saw, cut along the line cre-
ated in Step 2 to remove the excessive extension collar.
Step 4: Reinsert the extension collar into the adapter
ring ensuring that the cover alignment key on the ex-
tension collar is aligned with its recess in the adapter
ring. Reset the extension collar height to the dimension
determined in Step 1.
