Everything you need to know before you buy.
Most likely, yes. Our stopper is designed to fit standard sliding tracks found in homes, apartments, and condos across North America and Europe. It measures 9.8 cm × 7.1 cm × 2.5 cm. If your track is unusually narrow or wide, just measure before ordering—we're here to help if you're unsure!
Nope—zero tools required. Simply slide it into your track, position it where you want, and you're done. It holds firmly in place through friction and smart design. Perfect for renters who can't drill holes or modify their space.
Absolutely. You control the exact opening distance by sliding the stopper to your preferred position along the track. Want a 6-inch gap for ventilation? Done. Need to limit your balcony door for safety? Easy. It's fully adjustable and repositionable anytime.
That's exactly why we designed it. This stopper prevents doors and windows from opening too wide, giving you peace of mind in high-rise apartments or homes with curious toddlers and pets. It's a simple, effective safety solution that doesn't compromise your view or airflow.
Not if your tracks are clean. The stopper is made from smooth, non-abrasive material that won't scratch aluminum or vinyl frames. Pro tip: Wipe down your tracks before installation and avoid dragging the stopper across rough surfaces. Treat it right, and it'll treat your home right.
We've got you covered with our money-back guarantee. If it doesn't fit or meet your expectations, just reach out to our support team within 30 days for a hassle-free return. We're confident you'll love it—but if not, we'll make it right.
