Pin Fixed. Stairs. Flat Handrail

05/11/2013 •

The X1 Series point fixed frameless glass balustrade with flatbar handrail system is designed to fix to the face of the landing or stair stringer structure, with stainless steel point fix standoffs, without the use of any stanchions.

It can be fixed to a concrete slab edge with a minimum depth of 240mm, masonry, timber framing or steel beams.

The 50×10 handrail fully complements the X1 Series stanchions and is designed to maximise the views attainable through the balustrade whilst complying with the “interlinking handrail” requirements of AS 1288.
