Glass Vice and Clearline clamps are designed to accept either 9/16″ or 5/8″ laminated safety glass for frameless glass railing installations without a top cap rail, achieving the required 42″ guard height. For installations where a top cap rail is used, 1/2″ tempered glass is also an accepted specification.
For commercial applications — including stadiums, hospitality venues, and large-scale developments — Glass Vice hardware can accommodate thicker glass configurations. We recommend contacting Glass Vice USA directly to discuss the right specification for your project.
Glass specifications should always be confirmed with your glazier, installer, or engineer against local IBC and IRC requirements. Some jurisdictions have specific interpretations on laminated versus tempered glass for guard applications, and your Authority Having Jurisdiction (AHJ) has final say on what is accepted at permit stage.
