Model GBWM Copper Ground Bus Wall Mount is a very rugged device for mounting up to 4 Alpha Delta Model TT/ATT3G50 series broadband coax surge protectors. Heavy gauge (.0937, 13 ga.) copper prevents twisting or flexing from the weight of long coax cable runs. See photo for mounting details of supplied ground lugs, ring terminals and hardware. • Remove plastic PVC protective cover sheet from bus bar before mounting. Can hold up to 4 TT/ATT3G50 coax surge protectors. Can be used indoors/outdoors. • Use supplied stud and nut that comes with the TT/ATT3G50 units to mount units to bus bar. 2 Model TT/ATT3G50s units shown for illustration only. • Use anti-oxidant grease (Penetrox/Noalox) between protectors and copper bar. Be sure to seal mating PL-259 or N male connectors on coax, from connector shell over coax, for weather proofing. Check dealer for sealant types. • Wall mounting screws are common types (#10 pan head or common black drywall screws).
