093 Zinc Control Joint (ZNCJ)

Drywall or veneer plaster control joint

ClarkDietrich 093 Zinc Control Joint is applied between abutting gypsum panels and is used to relieve the stresses of expansion and contraction of drywall and veneer plaster systems in large ceiling and wall expanses over 30' in length.

Application(s): Drywall, DEFS, Plaster

#093 Zinc Control Joint is typically installed from door header to ceiling, from floor to ceiling in long partition runs, and from wall-to-wall in large ceiling areas. Zinc Control Joints are manufactured from high-quality pure zinc and can be used for interior or exterior applications where heightened corrosion resistance is required. The 1/4" by 7/16" opening is protected by plastic tape, which is removed after joint compound or plaster has been applied and the finish is completed.

Note: Where fire and/or sound ratings are required, a code approved and tested joint assembly must be installed behind the ZNCJ control joint. Consult construction documents for details of construction for the control joint assembly.
