CVGR Hercules Tempered Laminated Glass Panels are 13 mm thick and have a finished height of 42 in. They are test proven to hold an amazing 2,520# vertical load and a 820# horizontal load. Unlike hardwoods, glass railings don't need repeated painting or finishing for enhancing their durability. ClearView GLASS RAILINGS use 316 stainless steel solid core spigots that do not corrode when exposed to water. CVGR Hercules Tempered Laminated Glass Panels are available in 9 different widths (60 in., 54 in., 48 in., 42 in., 36 in., 30 in. 24 in., 18 in. and 12 in. ). This wide selection of panel widths ensures that Hercules Glass tempered laminated panels provide a solution for any width of every application. The space between CVGR Hercules Glass Tempered Laminated panels can be as small as 1/2 in. to as much as 4 in. Thus a small 2 panel installation may have as little as 1.5 in. total space between panels or as much as 12 in. total space between panels. This is a 10.5 in. spacing flexibility between panels with just a 2 panel installation.
