Windlocked Roller Shutters

For any roller shutter you install, consider the added advantages of a windlocking mechanism to help further safeguard it when closed. In tempest conditions, even strong building materials can get caught up and blown by high winds. In situations and locations where extreme wind and weather conditions are possible or likely, the windlock is a viable safeguard to keep shutters firmly closed.

Amongst our other satisfied customers, the Australian military have used our windlocked roller shutters to successfully hold tight, tarmac constructions exposed to the high wind strength of large helicopters and aircraft landing and taking off. As seen in this video, the windlocks firmly hold doors that could otherwise be blown in by the force of winds.

When constructing our windlocked roller shutters, Able Doors use a specially designed locking mechanism, along with curtain guides and steel end clips that interlock and hook together for superior strength and hold.

Custom manufactured with quality materials, right here in our Sydney factory in Wetherill Park, Able Doors’ windlocked roller shutters provide a protective solution for extreme conditions. If you are dealing with the unpredictability of severe weather conditions, or the predictable pressures of high wind force areas, it makes sense to cover your bases with Able Doors’ windlocked roller shutters.

Custom options

The shutters can be supplied as solid steel, or customised with slots or perforations for ventilation, to achieve up to a 37% airflow where needed.

We use conventional sprung drums or Dead Lift motor gear boxes with safety brakes to provide quieter motion when opening and closing. Anti-rattle devices can be fitted into the guides to further reduce the roller shutter’s operation noise. You can choose head or side panel construction, manual by motorised operation, and the bottom rail has an optional rubber weather seal available, and even a brush strip for vermin control.


We offer a range of colour options in Dulux powder coating, galvanised finish or polyurethane.


Able Doors’ roller shutters come with a 12-month warranty or 50,000 cycles for added peace of mind.

Materials and sizes

  • We use galvanised steel in gauges from 0.8mm to 1mm and extruded aluminium or steel for the bottom rail and the interlocking curtain slats, which vary in size as follows:
    • 50mm slat profile – for light Industrial applications
    • 75mm slat profile – for medium Industrial applications
    • 100mm slat profile – for heavy Industrial applications
  • The curtain interlocks with the bottom rail and slats are strengthened with steel or nylon end clips for strength, ease of motion and noise reduction.
  • The guides are folded steel G sections available in 100mm deep x 32mm wide.
  • The drum is manufactured from galvanised steel tubing of custom diameter size and thickness appropriate for the size and application of your project. The drum has self-lubricating bearings turning on a steel shaft with helical springs so as to counterbalance the weight of the curtain, for easier operation.
  • Locking has sliding shoot bolts, hasp and staples and with optional automatic gearbox, working in conjunction with Logic Control System, PE safety beam and handsets, or wired into you access control system.
