Door Restrictors

Door restrictors are safety and security devices designed to limit the opening range of a door, allowing controlled ventilation or partial access while maintaining security. They are commonly used in residential, commercial, and hospitality settings to improve safety, prevent overextension of doors, and enable partial viewing or communication before fully opening a door. At John Barnes Group, we stock a range of door restrictors to suit different applications, focusing on quality, durability, and ease of installation.

Our range includes three main types of door restrictors—Door Guards, Chain Bolts, and Spring Restrictors—each offering unique benefits depending on the intended use. Buy Door Restrictors online today from the John Barnes online shop!

 

What Are Door Restrictors?

A door restrictor is a hardware device fitted to a door and frame to physically limit the door’s maximum opening distance. Restrictors can enhance security, prevent damage from overextension, and provide additional control over how a door is used in daily operation.

They are especially valuable for situations where safety, privacy, and controlled entry are priorities.

 

Types of Door Restrictors We Offer

Buy Door Guards online

A door guard is a hinged arm mechanism that allows the door to open slightly while still keeping it secured. It provides a visual and physical barrier while allowing communication or limited ventilation.

Use cases:

  • Apartment entry doors

  • Hotel room doors

  • Residential front doors

Buy Chain Bolts online

A chain bolt consists of a short length of chain attached to the door and frame, allowing the door to open only as far as the chain permits. It is a traditional, easy-to-use solution for partial access.

Use cases:

  • Residential front doors

  • Older style homes

  • Doors where retrofitting is required without major modification

Buy Spring Restrictors online

A spring restrictor is a device installed on the hinge side of a door to control and limit how far the door can open. The spring action helps absorb force, reducing the risk of damage to the door, hinges, or adjacent walls.

Use cases:

  • Commercial and public buildings

  • Office entry doors

  • Schools and healthcare facilities
