The system supports two sizes of glass thickness 3/8” and 1/2”. The pictures are showing 1/2” glass.
The recommended distance between the posts is a maximum of 5ft for 1/2“ glass thickness and a maximum of 4ft for 3/8” glass thickness.
Our stock sizes are 36” and 42” high posts. When a top rail is needed, a cone handrail bracket (adjustable for stairs) can be mounted on top. Custom sizes are available at comparable prices.
Unfortunately it’s not available in 90° since the glass clamps are wide enough to get into each other when mounted at this angle. On the other hand other custom degree sizes larger than 110° can be fabricated at no additional cost. Our Virgina Round glass systemexists in 90° for 1/2″ glass thickness.
