Further Information

The AUTOPA Double Swing Height Restrictor has a standard clearance of 2050mm, limiting access to high sided vehicles. Ideal for use on commercial sites such as retail parks, it spans two carriageways, preventing vehicles from circumventing the access control measures in place. The booms of the height restrictor can be opened when required to allow full access, and locked in the open position if needed using additional catch posts.

Manufactured from galvanised mild steel, the body of the height restrictor is coated red as standard (other colours are available upon request; please state BS/RAL numbers at time of order). Available ragged or flanged, the Double Swing Height Restrictor can be fitted with a knocking bar and/or a maximum height warning sign. For additional security Swing Gates can be added to the height restrictor upon request.

Please note: Swing Gates cannot be retrofitted to height restrictors.
