The SG10 system comes in two options Semi-Frameless and Fully Frameless. The Semi Frameless has only a handrail on top and uses 15mm clear toughened glass. The handrail options are either a beautifully designed elliptical handrail or a small rectangular handrail. The SG10 frameless system allows for uninterrupted views without limitation of lengths or sizes and requires no posts at all.
