Frequently Asked Questions
What is the Light Gap Blocker Extension?
Sometimes Sleepy Time Tracks alone just don’t cut it—and that’s where Extensions come in.
They’re patented add-on pieces designed to work with your Sleepy Time Tracks, giving you extra reach for tricky installs. Each Extension is 2 inches wide and, when paired with sidetracks, can handle a wide variety of situations—including extra-wide gaps up to 2½ inches.
Made from durable, flexible vinyl, Extensions come in a clean white finish with black backing or black on both sides. They’re also paintable with latex paint if you’d like to match your trim. Extensions attach easily with the provided peel-and-stick adhesive, creating a seamless blackout fit.
When do I need the Light Gap Blocker Extension in addition to Sleepy Time Tracks?
The Light Gap Blocker Extension is made for those tricky situations where regular Sleepy Time Tracks need a little extra help. Common applications include:
- Extra-wide gaps that sidetracks alone can’t cover
- Shades that protrude past the window opening
- Outside mounts where tracks don’t sit flush
Because they’re so versatile, Extensions can also be used in many other ways to improve fit and blackout performance.
