Simply connects parallel panels, including panels with no clearance at the side. It can be surface-mounted or semi-recessed into the panel and its installation depth matches the Type 1 Button-fix, allowing the two fasteners to be used to hang adjacent panels. The Fix housing is moulded from PBT and the Button is acetal - both strong and durable engineering polymers. As a general guide, four Button-fix Type 3 fasteners on a vertical panel will support loads weighing up to a maximum of 132 lbs (60kg), provided that the screws and substrate are properly matched and all other installation instructions are complied with. Four Type 3 Button-fixes can also support a ceiling panel of up to 22 lbs (10kg). Manufactured in the UK.
