Rod is 12” x 3/8” dia. Part number RSP13 and ARSP13.This can be used on any flat surface with any degree pitch and the lightning rod can be adjusted with the swivel. Especially useful on rubber roofs, metal roofs or any roof you do not want to penetrate the surface with screws or nails. These are adhesive glue down bases. Apply the #UC Adhesive liberally to the base and put in place. Allow this to cure for 12 to 24 hours before connecting cable to it. The adhesive will cure faster under wet or more moist conditions. This adhesive will have a rubbery texture like silicone caulk when dry, but it will be secure. Aluminum rod is 1/2 inch diameter by 12 inches long. Available in copper or aluminum.
NEVER use aluminum for grounding. Transition from aluminum cable to copper cable by using the bimetallic connector #M3
