Answer:
The KJZ-03 is a 414 mm vertical stand engineered for mounting directly on turnstile and flap barrier tops, whereas the KJL-03 is a 1340 mm full-height pedestal engineered for direct floor mounting.
ZKTeco provides distinct mounting brackets depending on whether the installation is surface-mounted on a gate or freestanding on the floor:
- ZKTeco KJZ-03 (Part Number A80072766): Measures 414 mm in height and is engineered specifically for gate-top and turnstile integration.
- ZKTeco KJL-03 (Part Number A80072852): Measures 1340 mm in total length/height and is intended for standalone floor-ground installations when channel-version biometric readers cannot be placed on a gate structure.
