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 KFB800 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On power loss or evacuation the wings withdraw fully and stay withdrawn, as EN 17352 requires for escape routes.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; a model without figures has not had them published rather than estimated.

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 KFB800 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.
Complete the Lane
A barrier, a reader and a base.
Readers & Controllers
The signal that opens the lane
Barriers are supplied without readers. QR scanners, RFID and NFC readers, controllers and displays are chosen for each lane.
See readers and controllers →Barrier Pedestals
A base made for the barriers
Where the floor is not suitable for fixing, the barriers stand on a pedestal made to measure, for any type of barrier.

How We Deliver
Three ways to work with us.
Every model in the range is available as a supply-only order, as an installation integrated with the system you already use, or as a complete working solution. The choice is commercial, not technical — the hardware is identical.
01 — Equipment Supply
Hardware for your own integration
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 — Installation & Integration
Integrated with the system you already use
We install, commission and integrate Keyable flap barriers with virtually any professional access-control platform capable of exchanging the required commands and credentials. You keep your software; only the entrance changes.
- Everything in supply, plus:
- Site survey
- Installation and mechanical fixing
- Commissioning
- Integration with your existing access-control platform
- Staff handover and documentation
03 — Full-Service Solution
Everything, as one contract
One point of responsibility from site survey and commissioning through long-term local service support. You approve a design and take delivery of a working entrance.
- Everything in installation, plus:
- Software: entitlements, ticketing, attendance, occupancy
- QR, NFC and RFID identification
- Scheduled maintenance and online support
- Local after-sales service
- Extended warranty on the installed system
All three models cover the full range: speed gates, swing, flap and sliding barriers, tripod, full height and half height turnstiles. Scope, response times and warranty terms are set per project and confirmed in the quotation.
