This page presents the complete Round Base Plate & Cover range alongside the associated round base plate fitting family, providing a comprehensive overview of the stainless steel base fittings available for round tube handrail and balustrade post installations. As shown in the image, two fittings are presented side by side: on the left, the smooth bowl-shaped decorative cover with its curved domed exterior, and on the right, the flat circular base plate with its evenly spaced fixing holes around the perimeter, the two components that together form the complete Round Base Plate & Cover assembly.

The Round Base Plate & Cover is available in three supply configurations. Cover & Plate the complete two-piece assembly covers the full size range from 12.7mm through to 76.2mm. Cover Only is available at 38.1mm and 50.8mm for installations where the base plate is already in place. Mirror finish, a high-polish reflective surface, is available at 50.8mm only, providing a premium option for mirror-polished handrail systems.

The Heavy Duty Base Plate, available in 38.1mm and 50.8mm, provides a heavy-section cast base with reinforcing ribs for structurally demanding installations. The 1 Hole Round Base in Satin Finish is available in 50.8mm, providing a compact, single-fixing base for lower-load applications. The 2 Hole Round Base in Satin Finish at 50.8mm offers a twin-fixing square plate with a large central aperture for improved bending resistance. The 3 Hole Round Base in Satin Finish is available in 38.1mm and 50.8mm, delivering maximum structural performance through its triangular three-point fixing arrangement.

The Round Converters in Grade 316 stainless steel, available in Satin at 38.1mm and 50.8mm and Mirror at 50.8mm, provide the tapered conical adapter that transitions between the round tube and a base plate interface. Together, this range offers a complete, coordinated solution for every round tube post base connection requirement across the full spectrum of handrail and balustrade applications.
