Description

Our Sentry™ closure design concept relies on a simple locking ring that slides within a groove machined into the outer flange or hub. When expanded to the closed position, the locking ring securely locks the door into position. This design methodology, which is proven within the oil and gas industry, provides distinct advantages of integral safety and avoids the reliance on external clamps with combined screw thread expanders. Heavy-duty components are used to actuate the locking ring and are designed to withstand the rigors of long-term operation. Components are designed and arranged to ensure secure retention of all hinge hardware and simplified handling by fabricators.
