Mounting antennas to existing building structures, corner or flat mount and to existing tower structures in the past posed a problem for it usually consisted of going to site and measuring up were after a bracket then had to be designed to fit. With this in mind Graffo set of to design a multipurpose bracket witch could be kept as a stock item, and could work for most of the configurations required. The bracket gives a snug fit onto existing tower leg structures, therefore not creating any high stress points. The bracket is easily upgradeable with different pipe size clamps for deferent requirements. Clamps can be altered to change from a horizontal to vertical installation.
