Inquiry (采购产品): Sliding doors for processing app. I am working on a project that will require three sliding doors that will be pneumatically controlled and actuated. These will be wsed on 72" wide x 105" tall openings. Then I will require a sliding unit that can be mounted on a concrete ceiling and slide to close a 60"x60" hole. We are required to prevent damp warm air from traveling to the upper floor when the lift for the containers is not in use. This lift does not haul personell and this pass through to the second floor does not have any fire protection requirements. This is in an isolated area and the lift will be used in a dumb waiter application. **** Hidden Message ***** Randy Vogt 76028 Company: Tote systems International E-mail: rvogt@totesystems.com **** Hidden Message ***** rvogt@totesystems.com
