The Stainless Vertical Round Bar Holder is designed to securely hold a 12mm (1/2") round bar in a vertical position on a 42.4mm (1.66") diameter handrail. It is made from high-quality 316 grade stainless steel, known for its corrosion resistance and durability. This holder is suitable for use on handrails with a pitch ranging from 22 to 33 degrees. To install the holder on a metal handrail, a 6mm tapped hole is required. Please note that the round bar itself is not included with the holder.
