Introducing the BHSF/BHSFL, an extension of the retrofit Balco Hinge System (BHS/BHSL) that accommodates larger joint sizes, up to seismic-level movement with vertical and horizontal shear. The BHSF/BHSFL can open to a max of 24” (12” nominal joint at ±100% movement or 16” nominal joint with ±50% movement), while maintaining capacity for pedestrian loads.
