Extension Rail Assembly
When attaching the extension to the EG4
®
BrightMount Adjustable Cat1, first remove the original splice
connector. Then, insert the extension rail along with the new splice connector in its place. Be sure to
maintain a gap of 0.4 in. (10 mm) to accommodate thermal expansion and contraction.
Step 2: Install an “L” bracket on each end of the main beam as shown in the figure below. Secure
the “L” brackets to the main beam using an M8x80 mm bolt, a flat washer, a spring washer, and a 13
mm hex nut. Hold the M8x80 mm bolt head with a 6 mm Allen wrench and torque the 13 mm nut to
97 in-lbs. (11Nm).
NOTE:
If needing to expand the rail for solar panel’s above 43.3 in. (1100 mm), the end
user can purchase a rail extension kit to increase the rail’s length.
