⚠ Important Safety Information

Please read before purchasing or installing.

This accessory covers the interior controls of a door lock and may delay or obstruct the ability to unlock or open a door.

• Do not install on a door where it could interfere with immediate emergency exit.

• Emergency exits must remain operable without a key, tool, special knowledge, or additional unlocking steps.

• This product is not a certified child-safety device, security lock, or emergency-egress product.

• It is not guaranteed to prevent wandering, elopement, or unauthorized door operation.

• It should never replace adult supervision, door-open alerts, caregiver notifications, or an appropriate home safety plan.

• Buyers must verify installation suitability and compliance with applicable building and fire-safety requirements.

A cover that makes a deadbolt harder for a child to operate may also make it harder for someone to exit during an emergency. Please evaluate this risk carefully before use.
