Three articles, one decision, designed to be read in sequence by anyone spec'ing access control for a US commercial site.
The 2026 specifier's guide to choosing between speed gates, tripod turnstiles, and full-height turnstiles. Throughput, security tier, ADA + NFPA, vertical fit, and 7-year TCO.
Read part 1An 8-dimension head-to-head between optical speed gates and tripod turnstiles. Tailgating, ADA, integrations (Lenel, Genetec, Honeywell), MTBF, and the real lifetime cost.
Read part 2A 2026 cost guide for commercial turnstiles in the US. Real hardware bands, transparent installed-cost line items, lead times, and 5-year TCO, with no marketing fluff.
Read part 3Recently updated
3 articles updated in the last 30 days.
GuidesHow to keep a turnstile or speed gate installation ADA compliant: the 32-inch rule, companion swing-gate lanes, timing and force, egress, and the mistakes that fail inspection.
GuidesHow turnstiles and speed gates wire into HID, LenelS2, Genetec, and Honeywell: protocols, reader packages, REX, fire-alarm release, and anti-passback, explained for specifiers.
GuidesWhat to prepare before turnstiles arrive: power, conduit, flooring, structural blocking, surface vs embedded mounting, and lead-time sequencing for a smooth install.

Editorial standards
Four rules. The whole methodology fits on a sticky note.
Every claim is cited or labeled.
Manufacturer-published numbers cite the datasheet. Integrator-side estimates are explicitly labeled as estimates. Ranges include their source.
No sponsored content. Ever.
We don't accept payment to feature, promote, or omit. Our articles compare us against the competition honestly because the comparison holds up.
Articles are reviewed annually.
Codes change. Pricing drifts. The Updated date you see at the top of every article is the last time we walked the article line by line.
Real author. Named on every article.
Bylines are credentialed real people, not 'Gatestile Editorial Team.' E-E-A-T isn't a marketing checkbox; it's a discipline.
