Buttonfix now offers its Type 1 button-fix in a metal option with both the button and the fix being diecast in ZL2 zinc alloy. In addition to retaining all the benefits of the composite polymer versions, the metal button-fix is compliant for use with fire-retardant panels. It can connect parallel panels, be surface-mounted or semi-rebated into a panel, and orientated for vertical or sideways assembly. Also, it features a 316-stainless-steel spring, which allows for use in applications where vibration may be an issue.
