Shield — Total Blackout Blinds

Step 1: Measuring Your Window’s Recess Depth

Before measuring your window, check the recess depth to ensure there’s enough space for the Shield. The minimum required depth is 3 cm. To measure, start at the front edge of the recess (farthest from the window) and measure to the shallowest point.

Watch for Obstructions

Common obstructions within your recess space include:

• Window handles
• Latches
• Locks
• Winders or cranks

Measuring with Obstructions

Even with a deep recess, obstructions can block proper installation. To check clearance:

1. Measure the recess depth from the front of the recess to the window.
2. Measure the obstruction depth from the window to the front of the obstruction.
3. Subtract the obstruction depth from the recess depth to find the unobstructed space.

Important: You need at least 3 cm of unobstructed recess space to install the Shield securely.

Step 2: Measuring the Width

Since windows are often not perfectly square, you need to measure the width in three different places to account for any unevenness:

• Top of the window recess
  
• Middle of the window recess
  
• Bottom of the window recess
  

Record the smallest of these three measurements. This ensures your Shield fits the narrowest point of your window.

Step 3: Measuring the Height

Next, measure the height of your window recess. Once again, take measurements from three locations:

• Left of the window recess
  
• Middle of the window recess
  
• Right of the window recess
  

Just like with the width, record the smallest of these three measurements.

Avoid Common Measuring Mistakes

To get the most accurate measurements, avoid these common errors:

• Measuring at an angle: Always hold the tape measure straight and level.
  
• Bending the tape measure: Keep the tape straight to ensure accurate measurements.
  
• Rounding incorrectly: Round to the nearest tenth of a centimeter if needed.
