INTRODUCTION

The door-within-a-door design of a security door usually refers to a double-layered door, which includes an inner door and an outer door. This design not only improves security but also enhances insulation and soundproofing effects. The door bolt is part of the security door and is typically used to lock the door-within-a-door to prevent unauthorized access.
