ClarkDietrich H-Studs are 2" wide vertical members used to secure two 1" thick pieces of gypsum shaft liner in Area Separation Wall assemblies. H-Studs are inserted into C-Runners and slid over gypsum panel liner edges. The process is repeated until the desired wall length is achieved. 

Area separation walls are non-load bearing, 2-hour and 3-hour rated vertical wall assemblies that provide fire-resistant protection between adjacent living units in apartment buildings, condominiums and townhouses.
