How to Fit a Window Restrictor

HOW TO FIT A WINDOW RESTRICTOR

Window restrictors limit how far a sash opens, improving safety — especially for children’s rooms. Here’s how to fit one quickly and neatly.

🧰 TOOLS YOU’LL NEED

  • 🪛 Screwdriver
  • 📏 Measuring tape
  • ⚙️ Window restrictor kit – Shop Restrictors

🔧 STEP-BY-STEP GUIDE

1️⃣ Mark the Mounting Points

Position the restrictor arm 100–150mm from the hinge side and mark screw holes.

2️⃣ Drill Pilot Holes

Drill shallow pilot holes to prevent the frame from cracking.

3️⃣ Fit the Restrictor

Secure both arms with screws, ensuring they align correctly when the window closes.

4️⃣ Test the Operation

Open and close the window to confirm restricted travel and smooth locking.
