Key features & benefits
The height restrictor is available as a fixed or opening restrictor and is a simple & economic means of ensuring that vehicles above a certain height do not have access to a roadway or parking area.
The opening height restrictor consists of all steel construction coated white, (as standard), with a white powder coated aluminium arm with red fascal markings, and a knocking bar (optional) suspended by adjustable links, which can be altered on site. The other end of the support arm is secured in a catcher post, which is height adjustable, to take into account variations in the road camber. The arm is locked into the catcher post, through a padlockable, elongated bar which allows control from normal pedestrian height. A second catcher post is provided to lock the arm in the open position.
The fixed height restrictor, like our opening unit consists of all steel construction coated white, (as standard), with a white powder coated aluminium arm with red fascal markings, and a knocking bar (optional) suspended by adjustable links, which can be altered on site.
