Full-height access control with battery backup and onsite badge verification, deployed by forklift and connected to the Sitemetric platform.
Sitemetric is trusted by 90% of the top 20 ENR companies
At a busy construction site, every entry matters. The Mission Critical Turnstile Gen-3 combines physical security, backup power and offline access verification to help keep workers moving and access under control.
Integrated battery backup keeps the gate running through power outages.
A full-height, three-rotor barrier and anti-passback enforcement help prevent unauthorized access.
Onsite verification lets the turnstile check badges and log entries when connectivity drops, then automatically sync records when service returns.*
*The turnstile needs an initial connection to sync the current site access list. Without Wi-Fi or LTE it keeps running on the stored list but won't receive updates until it reconnects. While connected, the list updates regularly.
Construction sites are constantly evolving. Access points move, crews change and power or connectivity can be unreliable. The turnstile installs on your site in minutes, with no ladders, overhead work or technician dispatch.
The diamond plate base lifts by forklift. No crane, no concrete pad, no anchor bolts.
One standard 15A circuit powers a group of up to three units. The controller and communications hub are factory-integrated, so there's no field wiring.
On first power-up it connects to the Sitemetric cloud and downloads your site's access list, with no technician or IT setup.
Every entry and exit is recorded and connected to the Sitemetric platform, bringing access control, badging, AI cameras and mass texting into one system. One partner supports the turnstile, the platform, monitoring and Access Control Officers.
Headcount, hours and reports come straight from gate activity.
Sitemetric's AI agents and 24/7 monitoring team help detect equipment issues and support faster resolution, all within one integrated system.
The turnstile reads the same Sitemetric badge workers carry across your jobsites, whether or not a given gate has a turnstile.

Answers to common questions about power, connectivity, installation and certifications.
Integrated battery backup keeps the turnstile locked and monitored for up to two hours or 2,000 rotations, with automatic switchover. Entry is fail-secure and exit is fail-safe, both configurable in the field during setup.
Yes. Badges are verified at the turnstile itself, not in the cloud, so it keeps checking credentials and logging entries through a connectivity drop, then syncs records when service returns. It needs an initial connection to sync the current site access list. Offline, it runs on the stored list and receives updates once it reconnects. It connects over 4G LTE with dual SIM, plus Wi-Fi, so it doesn't depend on site IT infrastructure.
The turnstile arrives on a forklift-ready diamond plate base with the controller and communications hub factory-integrated, so there's no field wiring, anchor bolts or concrete pad. It runs on 120V, with one 15A circuit for a group of up to three units, and downloads your site's access list on first power-up.
Yes. Forklift pockets in the diamond plate base let the turnstile move as gate layouts change from excavation to fit-out, with no electrician and no permanent infrastructure to remove.
Each turnstile is rated for 15 to 30 people per minute in each direction. The number of lanes a site needs depends on peak crew size. Read the turnstile and badge reader guide for how to plan lanes.
A full-height turnstile is not an accessible route, so projects using them generally need an alternate accessible entry alongside. Ideally it reads the same credential and records the same access event, so the entry record stays complete.
It's UL 294:2018 Listed, CAN/ULC S319 Certified and FCC Part 15 Compliant, and manufactured in the USA.
