About Covers

A cover is a stainless-steel decorative plate that fits around the base of a railing post where it meets the floor, deck or fascia, concealing the anchor bolt, base plate and raw fixing beneath a clean, finished disc or square. It slides over the post tube before or after installation and sits flat against the mounting surface, giving the post base a professional appearance.

Strofix supplies base covers in seven variants — round covers in Ø85, Ø95 and Ø105 mm diameters for Ø42.4 and Ø48.3 mm round pipe posts, and square covers in 85×85, 90×90, 105×105 and 108×108 mm for flat-sided posts — in AISI 304 or AISI 316 stainless steel with satin or polished finishes and heights of 18 or 20 mm.

The correct cover depends on post shape and diameter, the desired cover size and the required steel grade.
