Designed to provide access control to unsupervised installations. Rugged construction ensures trouble-free performance and durability. Heavy duty mechanism can be mechanical or self-centering and electrically operated. A second set of electrical controls can be added for exit. Any combination of fail-lock or fail-safe is available. Turnstile can be fabricated from anodized aluminum with stainless steel arms (THT-100A), or complete stainless steel (THT-100S). Hot dipped galvanized steel (THT-100C), or powder coated steel (THT-100CP) are also available. The THT-100(3) has 3 rotor sections for 120 degrees of passage space, thereby allowing greater comfort in use. Bottom thrust bearing is dust and moisture proof. Open construction shield minimizes claustrophobic effect and increases visual security. Low voltage 24 VDC operating system requires normally open, momentary, dry contact to release turnstile. Clear anodized aluminum with stainless arms model THT-100EA is shown above.
