Tool-Free Child Safety Door Lock with Two-Sided Adult Release, Fits 3.5–4.5 cm Doors

Keep little ones out of bathrooms, offices and supply closets in seconds: this lock slides onto the edge of an interior door with no tools, no drilling and no adhesive.

Key Benefits

• Installs in seconds – Slide it over the door edge and frame; there is nothing to screw, drill or stick, so your paint and trim stay untouched.
• Adults open it from either side – Push the latch back on one side or pull the sliders on the other, so nobody gets locked in or out.
• Placed out of reach – Mounted high on the door edge, it stays away from small hands while you open it with one hand.
• Switch off when you don't need it – Flip the switch to disengage the lock and the handle works normally again.
• Remove or move anytime – Take it off or reposition it to another door without leaving a trace.

Once a toddler starts exploring, every interior door becomes a way into something they shouldn't reach: cleaning products in a closet, a bathroom, a home office full of cables. Knob covers are easy for curious kids to work out, adhesive locks can pull paint off when removed, and many latches need a drill.

This lock avoids all three. It clamps onto standard interior doors 3.5–4.5 cm (1⅜–1¾ in) thick with a 3.5 cm (1⅜ in) wide jamb, sits out of a child's reach, and is made of ABS plastic with a rust-resistant stainless steel spring. Choose a single lock or a pack of up to five to secure every door that needs it.

How It Works

1. Slide the lock over the edge of the closed interior door and its frame.
2. To open as an adult, push the latch back on one side or pull the sliders on the other.
3. Don't need it for a while? Flip the switch to disengage the lock so the handle moves freely.
