WR120B Zip Screen: A Buckle-Guided Wind-Resistant Outdoor Shade System Rated for Level 12 Winds

What Is the WR120B Zip Screen?

A zip screen is an exterior shade that locks its fabric edge into side guide rails, so the screen cannot be pushed out of the tracks by wind. The WR120B is the buckle-guided version of that system. Instead of a slide rod running continuously through a fabric pocket, the leading edge clips into the rail — a design chosen around a mechanical stroke motor and around installers who need to fit and remove panels quickly.

The result is a wind-resistant outdoor shade that keeps its two jobs at once: it blocks sun and spray without sealing out the view, and it stays serviceable after years of exposure.

Key Structural Features

Buckle-Guided Design for Fast Installation

The WR120B is the dedicated buckle-guided version for mechanical stroke motor systems. Its structural design keeps installation deliberately simple — no complex sequence on site, and removal is just as direct. For contractors, that means shorter installation time per opening and faster turnaround when a panel comes back for servicing. For facility teams, it means cleaning and fabric replacement are routine maintenance tasks instead of a shutdown.

Mechanical Stroke Motor: Lower Cost, Stable Power

Two reasons to spec this pairing:

• Lower procurement cost. Mechanical stroke motors carry a clear price advantage over other motor categories, which keeps the total cost of a multi-panel order predictable.
• Mains-power durability. They run directly on mains power in demanding duty conditions, with fewer operating constraints and broader site compatibility than low-voltage alternatives.

Oversized 120 × 120 mm Square Hood

The hood measures 120 × 120 mm — larger than a standard zip screen cover. The extra section does three things: it absorbs greater impact load, it carries the rolled fabric more stably, and it keeps dust and rain away from the internal components. On a coastal or exposed site, hood protection is a direct input to service life.

Level 12 Wind Resistance

Wind performance comes from the whole edge system, not from one component. The WR120B pairs a high-tensile wind-resistant fabric with reinforced guide rails, and the configuration was validated through hundreds of simulated test cycles before release. The outcome is Level 12 wind resistance: the fabric stays locked in the rails under sustained wind load, so the interior behind it stays shaded, dry, and quiet while the weather works on the outside face.

Four Operation Options

Drive selection is what adapts one product line to a mixed project schedule. The WR120B offers four:

Bead Chain and Manual Push

For a residential sun room or a single terrace opening, bead chain and manual push are the lowest-friction options — no wiring, no commissioning, and operation anyone in the household can use.

Crank Operation for Power-Free Locations

Where there is no power run, a crank drive removes the constraint entirely. It suits rear yards, boat docks, garden structures, and retrofit sites where pulling a cable would mean new conduit work.

Motorized Operation for Large and Multi-Panel Facades

Hotels, office buildings, and restaurant frontages generally run large openings and multiple panels. Motorized operation supports remote control and group management, which cuts daily operating time and keeps several openings moving on one schedule.

Where the WR120B Works Well

Hotels, Office Buildings, and Large Facades

On a commercial facade, the WR120B handles solar gain and wind-driven rain across full-height glazing while presenting a clean architectural line. Motorized control lets one operator manage the whole elevation.

Sun Rooms, Patios, and Irregular or Slanted Walls

Over a sun room or terrace, the buckle-guided edge holds the fabric under gust load and blocks light leak along the sides. Slanted and irregular wall geometry — the usual reason a standard outdoor blind gets rejected on site — is a case this system is designed to cover.
