Scope of Use

JH Clamp Balustrade is for Domestic and Residential Occupancy types A, A Other and C3 and for Commercial Occupancy Types B, E, A Other and C3 Occupancy Types as per AS/NZ 1170.1.2002. 

Edgetec JH Clamp balustrade is suitable for deck and balcony barriers, internal stairways or landings and can be fixed to timber (including waterproof decks), concrete, and steel.

Additionally, the JH Clamp system is available with a detail that hides both the external boundary joists and the JH Clamp, so the glass panels have no obvious fixings.
