Installation Procedures

Tighten the hardware if the seam is correct starting from the center and working towards
the outside of the reflector. Before tightening hardware, verify that the reflector seam
gap is even along its length. Push from both directions of the seam if necessary.
NOTE: The installer positioned inside the reflector must hold the bolt head with a
wrench, while the nut on the outside is tightened.
