The Square Base Plate Cover is a stainless steel decorative cover fitting designed to conceal the square base plate, fixing bolts, and structural connection hardware at the base of a square tube handrail post. As clearly shown in the image, the fitting presents a flat-topped rectangular cover body with a smooth, flat upper face, clean vertical sides, and two open channels or slots visible on the underside at each short end the slots enabling the cover to be slid or pressed over the square base plate assembly to lock into position and conceal all hardware beneath a neat, flush-faced rectangular stainless steel enclosure. The compact, precisely formed body presents sharp, clean corners and a consistent satin-finished surface across all visible faces.

This page also presents three related handrail bases and wall mounting fittings from the same range.

The Oblong Plate in Satin Finish at 38.1mm and 50.8mm is a compact oval-rectangular base fitting with a raised central tube-receiving boss and two end-positioned fixing holes, providing a dual-bolt floor or wall mounting solution for round tube handrail posts where a space-efficient multi-point fixing is required within a minimal footprint.

The Wall Stop Mount 37° in Mirror Finish at 38.1mm and 50.8mm is a cast stainless steel wall termination fitting with the tube-receiving boss angled at 37 degrees to match standard staircase pitch geometry. The mirror polish provides a highly reflective, premium finish for high-specification mirror-polished handrail installations where surface consistency throughout the system is a design priority.

The 2 Hole Round Base in Satin Finish at 50.8mm is a flat square plate with a large central circular aperture and two symmetrically positioned fixing holes, delivering a balanced twin-bolt fixing arrangement that resists the overturning moment of a laterally loaded handrail post while maintaining a contemporary, minimal-profile base appearance. Together, these fittings provide coordinated base connection solutions across round and square tube handrail system requirements.
