Riga Roof Window Wind Restraint System
Riga Roof Window Wind Restraint System
The Riga Roof Window Wind Restraint System is a stainless steel cable kit that limits how far your Riga roof window can open in high-wind conditions. When the automatic opener pushes the window open, the restraint cables act as a tether — preventing the window from being blown fully open, over-extended, or torn off the frame by strong gusts. Each kit covers one roof window and includes all hardware needed for installation.
Compatible with: Riga IIs, Riga IIIs, and Riga III.
What’s Included
- 2 × 15" stainless steel cables

Wind Restraint vs. Quick-Release Arm — What’s the Difference?
| Feature | Wind Restraint Cables (this product) | Quick-Release Arm (on the opener) |
|---|---|---|
| Function | Limits maximum window opening angle; prevents window from being blown open or off | Allows the opener to be manually disconnected from the window frame |
| When Used | Passive — always in place; activates automatically if wind pushes window beyond cable length | Active — manually disconnected before adverse weather; requires user action |
| Protects Against | Window being blown fully open or off the frame during a sudden gust | Opener piston being damaged by snow weight or forced closure |
| Installation | Permanent — cables remain attached at all times | Built into the opener; no separate installation |
The wind restraint cables and the quick-release arm serve complementary but different purposes. The cables are a passive safety system that limits window travel — they are always in place and require no user action. The quick-release arm is an active mechanism that you manually engage before a storm to disconnect the opener from the window. For maximum protection in high-wind environments, both systems should be used together.
How Many Kits Do You Need?
| Model | Roof Windows | Kits Needed (all windows) | Total Cost |
|---|---|---|---|
| Riga IIs | 1 | 1 | $32.99 |
| Riga IIIs | 1 | 1 | $32.99 |
| Riga III | 1 | 1 | $32.99 |
Each kit covers one roof window. All three compatible models (IIs, IIIs, III) have one roof window each, so one kit is sufficient for full coverage.
Note: This wind restraint system is designed for the Riga IIs, IIIs, and III. If you have a Riga IVs, IV, V, or XL model with multiple roof windows, contact us to confirm the correct restraint system for your model.
Frequently Asked Questions
Do I need the wind restraint system if my opener already has a quick-release arm?
They serve different purposes. The quick-release arm lets you manually disconnect the opener before a storm — but it requires you to be present and take action. The wind restraint cables are passive: they are always in place and automatically limit how far the window can open if a sudden gust hits while you’re away. In high-wind areas, both are recommended.
Is this compatible with the Riga IVs, IV, V, or XL models?
This kit (SKU RIGA-WIND-1) is specified for the Riga IIs, IIIs, and III. If you have a larger Riga model, contact us before ordering to confirm compatibility and the correct kit for your roof window configuration.
Does one kit cover both roof windows on models with 2 windows?
No — each kit covers one roof window. The Riga IIs, IIIs, and III each have one roof window, so one kit provides full coverage for these models.
Are the cables stainless steel?
Yes — both cables are stainless steel for corrosion resistance in the humid greenhouse environment.
Is this included with the greenhouse or purchased separately?
The wind restraint system is sold separately. It is not included in the standard Riga greenhouse package. It is recommended for installations in areas with frequent high winds or exposed sites.
