Specification:
Dimensions 3.25 inches L x 1.5 inches W x 4.5 inches H

Adhesive Compatibility Suitable for flat, smooth surfaces; not compatible with textured doors
Locking Mechanism Locks door from both sides once activated
Activation Access Caregiver must deactivate to open door
Suitable Door Type Flat-panel doors with sufficient flat surface for installation

Many people assume that a simple sticky lock for a door lever isn’t sturdy enough to keep a curious toddler out. I thought the same at first, but after trying this Wappa Baby door lever lock, I realized it’s surprisingly reliable.

The first thing I noticed is how solid the adhesive is. It sticks firmly to flat, smooth doors, and I was impressed by how securely it stays in place even after repeated use.

Just make sure your door has a flat surface—no textured or uneven areas—because gaps will prevent the adhesive from working properly.

Installing it took seconds. You just peel off the backing, press it onto the door next to the lever, and hold for a few seconds.

Once activated, it locks the door from both sides, which is a relief for peace of mind. But here’s a trick: you need enough space—at least 4.5 inches high and 1.5 inches wide—to fit it properly.

Using it is straightforward. When activated, the lock prevents the door from opening, and only an adult can deactivate it from inside or outside.

I found it perfect for bedrooms or bathrooms where I need to keep my little one safe without constantly monitoring every move.

One thing to keep in mind: it won’t stick to textured or uneven doors. Also, if you have a door with a small flat space next to the lever, it might be tricky to install.

But overall, this lock offers a simple, effective solution that provides peace of mind without complicating your day.
