What you will need
Each Guard is tailored to your window’s exact dimensions. For a perfect fit and total darkness, accurate measuring and proper installation are essential.
Free measurement guarantee
If the fit is not right, we remake it to your updated measurements and reship it with express delivery at no additional cost.
Step 1: Measuring Your Window’s Recess Depth
Before measuring your window, check the recess depth to ensure there’s enough space for the Guard. The minimum required depth is 1.18 inches. 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:
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 1.18 inches of unobstructed recess space to install the Guard 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:
Record the smallest of these three measurements. This ensures your Guard 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:
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:

What's in the box?
Installing your Guard is quick and straightforward and takes just 5 minutes. No tools are needed for the installation.
Step 1: Lay Out The Frames
Unpack the side frames and place them on a clean, flat surface, parallel to each other with their inner channels facing inward for assembly.
Step 2: Position the Top and Bottom Frames
Place the top and bottom frames parallel to each other, and verify that the numbered labels on the adjoining ends match.
Step 3: Connect the Frames
Connect all of the frames together by connecting the fabric and the side frame with the upper and lower frames.
Step 4: Tighten the Cords
Proceed with this step only if your blinds do not latch properly. Using the included screwdriver, tighten the two side-frame screws to tension the internal cords.
Step 5: Insert the Corner Caps
Press-fit the 8 included corner caps onto all frame corners - 4 on the front side, 4 on the back side.
Step 6: Peel back the brush strip backing
Peel off a small part of the protective backing from the brush strip.
Step 7: Apply the brush strip
Press the brush strip down as close to the back side of the frame as possible, leaving free space above it for the weather strip.
Step 8: Split the weather strip
Split the provided weather strip into two equal parts.
Step 9: Peel back the weather strip backing
Peel a small length of the protective backing off one end of the weather strip to begin. You'll peel away the rest as you go.
Step 10: Apply the Weather Strip
Apply the weather strip directly above the brush strip. Continue peeling the backing as you go.
Step 11: Insert and Test Guard
Place the blinds inside of your window recess. Test the blinds by opening and closing them.

Yes! Our Quartz Nolight blinds block out light just as effectively as our Graphite, Navy, and Titanium options.
Nolight is designed to fit most standard windows, but there are a few things to keep in mind.
Our blinds are not suitable for windows that aren't square, and they require at least 1.18 inches of clear recess space for proper installation. If your windows don't meet these requirements, Nolight may not be the right fit.
Below, you'll find a list of compatible and incompatible window types to help you determine whether Nolight is right for your home.
For the best fit, please read our Measuring Guide before placing your order. Accurate measurements are essential to ensure your Nolight blinds fit your windows perfectly. Please double-check your measurements, as incorrect measurements may result in blinds that don't fit properly.
Nolight blinds are easy to maintain. The non-woven polyester fabric helps resist dust and stains, so all they need is an occasional wipe with a damp cloth. No special cleaners or treatments are required.
The interior of your Nolight blinds matches the fabric color you choose, while the exterior is always Quartz to help reflect sunlight and heat. For example, if you choose Graphite, the inside will be Graphite, while the outside remains Quartz. This design creates a clean, consistent look from the outside while helping reflect sunlight.
To install Guard, follow our step-by-step instructions in our Installation Guide.
