Drilling a hole “no greater than 1/8” (3mm) larger in diameter than the hardware being installed”, per 33.5.6, can avoid excessive wounding in decayed areas, if that hardware is the cable itself. “When installing through-hardware”, 33.5.10 calls for washers to be used, and 33.5.20 states that “Installations shall follow manufacturers’ recommendations”. However, the makers of two fasteners on the market that anchor cables installed through limbs, wirestops and wedge grips, do not require washers because these fasteners are wide enough for most applications. It may be best to use washers anyway, until that standard is changed. ANSI standards are reviewed on a 5-year cycle, so they can incorporate new technology and research.
Through-fasteners do need more recognition. this may happen if users send their comments and experience to their A300 reps.
