How close to the edge a side-mounted glass balustrade can be installed depends on the material of the substrate, fixing, and the load. There is no single edge clearance that works for all railings and substrates, so the distance is determined based on the design. The correct distance protects both the substrate and the railing.
In concrete, the fastener must be placed far enough from the edge so that the load does not cause cracks; the distance depends on the type and size of the fastener, the concrete, and the load on the balustrade. In wood, the most important thing is that the fastener reaches a load-bearing stud or beam. The profile or post must be supported against the substrate. Check the substrate and the distance from the edge before drilling.
