Door Restrictor

A uPVC Door Restrictor, also known as a Door Stay, is a device that limits the amount a door can open. It is typically installed on the top or bottom of the door frame and is used to prevent the door from opening too far. It works by physically blocking the door from opening past a certain point, or by using a spring-loaded mechanism to resist the opening of the door. This can be used for security or aesthetic reasons, as well as to prevent damage to the door or surrounding walls. Door Restrictors can also be designed to blend in with the existing door hardware, maintaining the overall look of the home. At MB DIY, we offer the most stylish and robust Door Restrictors, also known as Door Stays for both Composite and uPVC doors.


Securing Your Space: The Many Benefits of Using Door Stays

A uPVC Door Restrictor has several benefits that make them a popular choice for both residential and commercial properties. Their first benefit is their increased security. These devices are designed to limit the opening range of the door, making it difficult for intruders to gain access. We provide three types of door restrictors at MB DIY: Lockable, Non-lockable, and Door Guard restrictors. Each one has a distinct appearance and purpose.

Lockable Door Restrictors

A Lockable Door Stay is a great solution for doors that need to be secured in a closed position. These restrictors are designed to hold the door open at up to 90 degrees, making them perfect for use in various settings such as schools, hospitals, and offices. The unique end snapper feature of these restrictors helps to keep the door securely in place, preventing it from being opened without a key or other unlocking mechanism.

A Lockable Door Stay is suitable for use with uPVC, aluminium and composite doors that have a euro groove in the sash. The adjustable friction device allows for easy customization to suit different door types and weight. These restrictors are also fast and simple to fit, with multiple screw ports for easy installation and a universal fixing/striker plate. All necessary fixings are also supplied, making it an easy and convenient DIY solution for any door.

Non-Lockable Door Restrictors

Non-locking door restrictors are a practical and convenient solution for controlling door movement in a variety of settings. These restrictors are constructed from durable materials and are designed to prevent damage caused by swinging or striking. They automatically engage when the door is opened and restrict movement to a maximum of 90 degrees. The restrictors can be easily installed into an air gap of between 4-12mm and feature adjustable friction to suit different door types and weights. They are also compatible with uPVC, timber, and composite doors, making them a versatile option for any building. With its easy installation and versatile functionality, these non-locking door restrictors is a must-have for anyone looking to add an extra layer of security and control to their doors.

Door Guard Restrictor

A Door Guard is an effective security solution for your front door. It is an adjustable bar that can be placed on the door frame, blocking it from being pried open from the outside. Unlike a door chain, it offers a sturdier and more durable option to secure your property. Additionally, Door Guards are budget-friendly and come in various colours, making it easy to find one to match your decor. If you want to bolster the protection of your home or business, considering a Door Guard is a smart choice.

A Must-Have for Safety and Security

Door Stays are a great option for both residential and commercial properties, providing increased security, energy efficiency, safety, and easy installation and maintenance. With the added benefits, it is clear that a UPVC door restrictor is a smart choice for any property owner looking to improve the security and energy efficiency of their property.
