BP-R42 Stainless Steel Railing Base Plate for Ø42.4 mm Post
The BP-R42 floor base plate anchors a Ø42.4 mm round railing stanchion securely to concrete, stone, or wooden floors. As the compactest member of the round-post base plate range, it suits residential balustrades, interior railings, and light commercial decks where a 42.4 mm tube is the specified handrail post size.
Precision cast in SS304 / SS316 stainless steel, it combines pre-drilled anchor holes with a welded socket that receives the post tube, giving installers a simple, bolt-down fixing that reads cleanly once a cover plate is fitted. The compact footprint also leaves room for adjacent glass panels and floor finishes on tight stair and balcony layouts.

A matching cover plate is then fitted to conceal the anchor bolts and leave a tidy base detail on compact stair and balcony layouts.
