01
Wings that withdraw
A flap retracts into its housing rather than sweeping through the lane. No arc means no clearance zone, so barriers can sit closer to walls, columns and each other than any swing gate allows.

Flap Barriers
Wings that withdraw instead of swinging. Nothing sweeps into the walkway, so the lane needs no clearance around it — the reason flap barriers hold their ground in transit halls and tight lobbies.

Key Features
Built for the lanes that have no room to spare.
02
From 800 mm of floor
The KFB1000 occupies 800 mm — the smallest footprint in the entire Keyable range — while still carrying a full 600 mm passage, readers and infrared safety.
03
A column of infrared
Sensor windows run the full height of each inner face, reading presence across the lane rather than at a single line. That is what separates anti-tailgating from a simple beam break.
04
Fail-open by law
On power loss or evacuation the wings withdraw fully and stay withdrawn, as EN 17352 requires for escape routes. A retracted flap leaves the lane completely unobstructed — there is no arm left standing in it.
The Range
7 models in the flap barrier family.
Shared electronics, readers and control across the family. What changes is the housing, the finish and the setting each one is built for. Technical figures as published by the manufacturer, March 2026; a model without figures has not had them published rather than estimated.

Five lanes at peak flow, ticket validation at the gate, no arc sweeping into the crowd.
University Library
A single discreet lane at the threshold — controlled access that does not announce itself.
Common Questions
Answers, briefly.
What is a flap barrier?
A flap barrier is a pedestrian gate whose wings retract into the housing instead of swinging across the lane. Because nothing sweeps outward, it needs no clearance zone around it.
What is the difference between a flap barrier and a speed gate?
A speed gate swings its glass wings through an arc and needs clearance either side. A flap barrier withdraws its wings into the body, so it can sit hard against a wall or another lane.
What is the smallest Keyable flap barrier?
The KFB1000 occupies 800 mm of floor, the smallest footprint in the range, while still carrying a full 600 mm passage, readers and infrared safety.
How do flap barriers prevent tailgating?
Infrared sensor windows run the full height of each inner face and read presence across the whole lane rather than at a single beam, so a second person following through is detected.
How We Deliver
Two ways to work with us.
Every model in the range is available either as a supply-only order or as a complete installation. The choice is commercial, not technical — the hardware is identical.
01 — Supply
Hardware only
You already have an integrator, an access platform and a programme. We deliver the equipment and the paperwork, and stay out of the way.
- Barriers, readers and controllers
- Technical datasheets and dimensioned drawings
- CE marking and EN 17352 declaration
- Delivery to site, anywhere in Europe
- Manufacturer warranty
- Spare parts held in Europe
02 — Turnkey
Everything, as one contract
One point of responsibility from the site survey to the fifth year of service. You approve a design and take delivery of a working entrance.
- Everything in supply, plus:
- Software: entitlements, ticketing, attendance, occupancy
- Installation and mechanical fixing
- Commissioning and integration with your systems
- Staff handover and documentation
- Scheduled maintenance and online support
- Extended warranty on the installed system
Both models cover the full range: speed gates, swing, flap and sliding barriers, tripod and full height turnstiles. Scope, response times and warranty terms are set per project and confirmed in the quotation.
