Blinds and shades are installed to windows to control the amount of light pouring into your house and to provide privacy. Despite this you find that most shades end up leaking at least some light into your home. This light may be acceptable to some, but it can be a real pain to others, especially in critical spaces such as a bedroom or media room.


Product Detail

Light leak happens due to light gaps that are formed when the blinds and shades that you have chosen for your windows don’t make a snug fit on your windows. This is common on any inside mount shade. A great solution to this issue is to use light blockers to cover those gaps on the sides of the window. These are pieces of material that are added to the insides of the window trims to help seal off light.

Special Features of Light Blocker

  • The Universal Light Blocker comes in one color, ‘white’
  • Each blocker is a two piece set: a base that is installed to the window frame, and an extension that is slotted into the base for light control.
  • These blockers are designed to be cut down and trimmed on site so that they fit your window specifically. When you order, you should order at a size larger than the height of your window for the sides, and larger than the width of your window for the sill. Note that there is a height tolerance of 1/8 to 1/4" from the ordered height of the blocker.
  • These light blockers can be added on to any blind or shade so long as you have enough depth to mount them. They are designed to cover a maximum gap of 1 1/2" in width.

Installing Miracle Fit to Your Blinds

To install your Miracle Fit to the blinds follow the simple steps given below:

Step 1: Take all required measurements.

Take measurement of the height of the window from the top to the bottom of the window frame. Measure the gap between the window frame and the window covering fabric, and measure each side separately. Measure the distance of your window covering from the back of the window frame. Order at a size larger than your needed measurements so that you can cut it down to perfect fit.

Step 2: Cut the Pieces.

Using your height measurement, cut the base to achieve your total height.

Step 3: Installation

Using depth measurement place light marks along the side of the window frame so you can line up your base in a straight line. The light blockers should be installed in front of the shade as close to the fabric as possible without impeding its movement.

Take a piece of the base and peel the seal off of the back exposing the double sided adhesive, attaching it to the sides of the window opening starting from the bottom of the window up along the markings on the window frame. Firmly press the piece onto the window frame and clip the extension to the base. Your Universal Light Blockers for your shades are successfully installed.


- Miracle Fit comes in a two piece set always, Miracle Fit Base and Miracle Fit Extension.
- For Installation the Miracle Fit Base has two sided tape attached to it that is peeled off when installing on the inside of the window trim. If necessary silicone can also be used around the edges of the base or screws can be drilled through the back lip of the base for extra support.
- Optimum positions for installing the Miracle Fit is either directly behind the fabric of the shade or parallel to the fabric of the shade depending on the needs of the customer. The Standard 1 1/2 ” Miracle Fit will be used the vast majority of times as gaps on the sides of the shades or blinds rarely exceed 1”.
- For shipping and packaging purposes, when the Miracle Fit is ordered with shades or blinds at the time of order the Base will be cut to the maximum width of the blind and you may have multiple pieces of the Base being sent depending on the height of the shade ordered but the Extension will always be the full height of the shade or blind ordered in one full length piece.
- When ordering the Miracle Fit please keep in mind that you are ordering two times the height of the shade as it goes on both sides and we will round up to the nearest foot. If a Miracle Fit Sill Option is required then you require two times the height and one time the width of the shade to be ordered for the Miracle fit.
