Basic Types & Structural Differences Turnstiles are split into half-height and full-height models by barrier height. Half-height turnstiles (approx. 1.2m tall) only guide traffic flow with weak anti-climb performance. Full-height turnstiles stand 1.8–2.2m tall to create full physical isolation, eliminating climbing risks, making them standard for high-security sites like factories, construction yards and prisons.By barrier quantity, they divide into 3-rod and cross-rod full-height turnstiles. The 3-rod desig…
