SNAP-IN INTERIOR CURVED SPECIFICATION 

NOTICE: Consult your local Simplex representative or contact Simplex at 800.638.5726 before specifying any optional or custom metal system as shape, material, size, perforation and finish limitations can affect feasibility. The options provided in parentheses are not always compatible

LIMITATION: The SNAP-IN ceiling system is not intended for use in kitchens, food processing, food preparation and cleanroom applications due to potential harsh environments and aggressive sanitation requirements. We recommend an independent evaluation before specifying the SNAP-IN Interior ceiling system in these areas
