Oversized vehicles cause serious damage to car park structures, low bridges, and building canopies. Height restrictors prevent vehicles exceeding a set height from entering restricted areas. Boom barriers control all vehicle access. Together, they're essential for car park and site management.
Why You Need Height Restrictors
- Prevent HGVs and tall vehicles damaging low structures
- Protect multi-storey car park ceilings and beams
- Stop caravans and motorhomes using car-only car parks
- Reduce insurance claims from structural damage
- Visible deterrent — drivers see restriction before entering
Types Available
Fixed Height Restrictors
Permanent steel bars at a set height. The simplest and most cost-effective option. Ideal for car parks with a single maximum height requirement.
Swing-Open Height Restrictors
Hinged bars that can be opened for occasional oversized access (deliveries, emergency vehicles). Lockable in both positions.
Manual Boom Barriers
Counterbalanced arms operated by hand or key. Control vehicle entry/exit at car parks, depots, and private roads. No power supply needed.
Automatic Boom Barriers
Motorised arms with remote control, intercom, or access card operation. For high-security sites and busy car parks.

Frequently Asked Questions
What height should I set my restrictor?
Measure the lowest point of your structure and subtract 200mm for safety clearance. Standard car parks typically use 2.0m or 2.1m restrictions.
Do height restrictors need planning permission?
On private land, generally not. On public highways or council car parks, check with your local authority.
