Your Comprehensive Guide to Doorway Height Restrictors


Types of Doorway Height Restrictors

There are several types of doorway height restrictors available to suit various needs and applications. Here are the most common types you'll encounter:

Fixed Height Restrictors: These restrictors are permanently installed at a fixed height, providing a constant barrier at the entrance or exit of a facility. They are commonly made from durable materials like steel or aluminium to withstand wear and tear.

Adjustable Height Restrictors: These restrictors allow for height adjustments, making them suitable for facilities with varying height restrictions. They typically feature a telescopic design or removable components to accommodate different clearance requirements.

Removable Height Restrictors: Designed for temporary use, these restrictors can be easily removed when not needed, allowing for unrestricted access. They are ideal for situations where height restrictions may change or when occasional access for over-height vehicles is necessary.


Selecting the Right Doorway Height Restrictor for Your Facility

When choosing a doorway height restrictor for your facility, consider the following factors:

Clearance Height: Determine the maximum allowable height for vehicles and equipment entering the restricted area. This will help you choose the appropriate restrictor height.

Material: Doorway height restrictors are typically made from steel or aluminium. Both materials offer durability and resistance to corrosion, but aluminium is generally lighter and easier to handle.

Customisation Options: Consider whether you require customisation options such as specific colours, signage, or reflective materials to increase visibility and match your facility's aesthetic.

Installation Requirements: Evaluate your facility's installation requirements, including whether you need a fixed, adjustable, or removable restrictor, and the type of mounting hardware needed.


Installing and Maintaining Your Doorway Height Restrictor

Proper installation and maintenance of your doorway height restrictor are crucial for ensuring its effectiveness and longevity. Follow these guidelines:

Installation: Hire a professional installer or consult with the supplier for specific installation instructions. Ensure the restrictor is securely mounted and properly aligned with the entrance or exit.

Maintenance: Regularly inspect the restrictor for signs of wear, damage, or corrosion. Replace any damaged components and perform necessary repairs to maintain the restrictor's functionality and safety.

Cleaning: Keep your doorway height restrictor clean and free of debris to ensure optimal visibility and performance.


Complying with New Zealand Regulations and Standards

While doorway height restrictors may not be legally required in all areas of New Zealand, they are highly recommended for promoting workplace safety and complying with regulations such as the Health and Safety at Work Act 2015. Consult with local authorities and industry-specific guidelines to ensure your facility meets all relevant requirements.


In summary, doorway height restrictors are an essential addition to any warehouse or facility, providing numerous benefits such as enhanced safety, accident prevention, and improved traffic management.
