Description
Flanged mounting base for balustrade ⌀42.4 mm – steel with holes

Flanged mounting base (collar) designed for mounting balustrade posts from tube with diameter 42.4 mm. Solid steel casting with three reinforcing ribs ensures rigid and durable connection of the post to the substrate. Three mounting holes enable secure fixing of the base to floor, ceiling or side of structure — ideal solution for installers of internal and external balustrades.
The element is ready for welding or press-fitting the balustrade tube into the central collar. Radially distributed reinforcing ribs increase the load capacity of the connection and prevent loosening of the post under lateral loading.

Internal diameter 42.4 mm corresponds to standard balustrade tube ⌀42.4 mm (1¼"), which guarantees full compatibility with the most popular balustrade systems available on the market.
