Product Description
QAB-R004 Premium Balustrade Glass Clamp
Stainless Steel 304/316 Square Balustrade Spigot in Mirror or Satin Finish QAB-R004

The QAB-R004 friction spigot is a square-flanged surface-mount fixing designed for frameless glass balustrades. Investment-cast in 2205 duplex stainless steel (SS304/SS316L optional), it delivers outstanding strength and corrosion resistance for demanding architectural applications. The versatile design accommodates both 12 mm and 15 mm glass panels via a friction-fit system that eliminates drilling through the glass – preserving panel integrity while ensuring a clean, minimalist aesthetic. Available in mirror or brushed satin finishes, with an integrated one-piece EPDM gasket, pressure plate, and raised cover ring included. Independently tested to relevant standards at a NATA-accredited facility.
