The package contains two reflector joint pieces (P/N 02750901), one 8’ reflector and 18 x #8 sheet metal screws.
Install the U-tube cover using the following procedure.
Step 10.2.1
Cut the 8’ reflector in half to be used on both sides to
cover the U-tube.
Step 10.2.2
Flatten 4’ reflector edge where joint piece matches. Put a
mark on the 4’ reflector, directly over the tube center.
Center the accessory joint piece on the mark and scribe
its contour on the reflector. Scribe the location of the
mounting holes.
Step 10.2.3
Cut away the reflector to clear the tube, leaving about 1”
of material inside the scribed contour to attach the
accessory joint. Drill or punch six 3 mm diameter holes in
reflector in the positions shown below.

Use six #8 sheet metal screws to attach the joint piece.
