AUTOPA Fixed Height Restrictor Barrier
The AUTOPA Fixed Height Restrictor is a durable access control solution designed to prevent high-sided vehicles such as HGVs, lorries, and caravans from entering low-clearance areas. This product is perfect for locations like multi-storey car parks, commercial compounds, or private estates where height restrictions are critical for safety and operational efficiency.
Manufactured from robust galvanised mild steel, each unit is powder-coated red as standard for high visibility and weather resistance. Custom colours are available upon request—please provide your RAL or BS colour code at the time of ordering.
With a clearance height of 2.2 metres (without knock bar) or 2.05 metres (with knock bar), it offers flexibility based on your site's specific needs. Maximum height warning signs can be included for enhanced safety and visibility at an extra cost.
Choose between bolt-down or concrete-in variants for secure installation depending on your site conditions.

Application & Installation
This height restrictor is designed for commercial vehicle access points where overhead clearance must be enforced. It is suitable for use in underground car parks, delivery bays, restricted entry routes, and similar B2B environments.
For bolt-down installation, the unit must be anchored to a pre-prepared concrete surface using M16 bolts. Concrete-in versions need a 600mm-deep excavation for foundation setting.
Clear warning signage is strongly recommended to alert drivers in advance of the restricted height. Please note: this is not included in the price.
