2x 900 mm height, 48.3 mm diameter pipes
Hot-dip galvanised steel construction
100x100 socket with tap bolt securing
Part of the GS89 ecosystem

APAC's GS89 galvanised steel headframes are designed to slip over the top of any GS89 series mast. The 100x100 socket secures over the 89 x 89 mm mast with the supplied 4x M12 tap bolts. The term spigot, tenon, and single-tube headframe are used interchangeably.

Two-Sector headframes, also known as butterfly mounts, provide two uprights offset from the central mast, doubling the real estate available for mounting equipment. The standard offset distance for GS89 mounts is 500 mm but fully customisable on request.

Constructed from a 900 mm (0.9 metre) length of 48.3x2.9 mm Circular Hollow Section welded to a 100x100 SHS socket. The central column is capped to prevent water ingress.
