I’m going to go through the features
of the GC1140 Ceiling Inlet. It’s an all urethane inlet. It has a removable lid with plastic clips. All the hardware is stainless or
plastic so you won’t have corrosion. The counterweight is adjustable to
open at different static pressures. And it has a feature so we can lock it shut. So if there’s time you don’t want the
ceiling inlets to open, you can put this string on here with an
actuator, or hand winch, whichever and lock it shut so they won’t function. Again, a gravity inlet with a
lockable option of shutting it up.
