Glass Mount Handrail Brackets

GLASS MOUNT BRACKETS
In a stairway, guard application – 42" high – codes will generally require that a handrail be provided at a height of between 34" and 38". With glass railing systems, these glass mounting brackets permit attachment of brackets directly to tempered glass structural balustrades.
NOTE:
These brackets require that a hole be drilled in the glass which must be done prior to tempering. Attempts to drill holes or grind the glass after tempering will most likely cause breakage.
*For 1/2" glass. For 3/4" glass, order longer bolts

HOLE SPECS FOR GLASS
Glass Mount Handrail Brackets require that a hole be drilled in the glass (3/4" hole for 1/2" glass; 9/16" for 3/4" glass) which must be done prior to tempering. Attempts to drill holes or grind the glass after tempering will most likely cause breakage.

Per ASTM C 1048, this chart should be used to determine minimum sizes and placement for tempered and heat strengthened glass.
