Try one before you buy multiple tracks.

Every window and every window treatment is different. Some shades have big gaps on the side, some very small. Some window frames are deep, some are very narrow. Sleepy Time Tracks can work in most situations, but we suggest before you buy multiple Sleepy Time Tracks, try one and see if it works on your individual window and treatment. We ship most orders out the next day and our return policy is 30 days from the date purchase, so you can purchase with confidence.

How many tracks come in each order?

Each order comes with 2 tracks. You can order with an optional bottom track, in which case you would get 3 tracks.

Sleepy Time Tracks are designed to be cut to size with a pair of utility scissors or tin snips.

I have stucco walls will they still work?

Stucco walls will require small screws to attach..

Do they work on outside mounts?

As long as the gap is less than 3/4 inch and you have a flat surface to mount the track.

Why are the inside black on a white track?

As the sunlight tries to transfer around the inside of the track it it best absorbed with black. We have tried other colors and found black works, by far, the best.

Can I remove the magnetic strip?

We use a strong adhesive designed to withstand various temperature changes and will pull off paint and more. For best results first heat with a hair dryer before removing. TIP WHEN FIRST INSTALLING……tape track in place with masking tape or such first, then you can reposition if needed before sticking magnetic tape. Once it is stuck, do not remove or it will compromise the adhesive.

Does it block 100% of the light?

Not much in life is 100%. We do not claim to block 100% of the light because every window is unique and different. Window frames can be off square, shades may not hang perfectly straight, the shade may have not be measured correctly. For these reasons, we cannot say that Sleepy Time Tracks are 100% light blocking, but they do an extraordinary job a blocking the majority of the light!

What is your return policy?

We offer a 30 day money back guarantee less shipping. Buyer pays return shipping fees.

Exactly as described! I’ve only installed them on one window so far and it’s already made a huge difference.

Exactly what we were looking for and took the guesswork out of finding a solution to darken my sons nursery. Easy to cut with tin scissors (as it says in the instructions) and the apply to the window. We ended up needing to place it in front of the shade a little bit but that’s because of how our shades fit the window. It still does the job! Glad we found such an easy solution!
