Height Restrictors
 
Height Restrictors are part of the Door Protection product range. They are of fully modular construction comprising, depending on internal height clearance requirements, fixed or modular ground level bollard 200 post units, intermediate post extension units, end extension units and top rail units.
 
Fixed ground level post units can be used up to a maximum internal height clearance of 3.4m and the modular ground level, intermediate and end extension post units can be used to provide an internal clearance to a required height. Up to internal heights of 3.4m units are free standing but above 3.4m the modular ground, intermediate extension and end extension post units are anchored using brackets to a suitable mounting surface. Units have been supplied and installed with height clearances of 7.75m but the actual achievable height limit is restricted by the physical and safety aspects of installation.
 
The maximum internal width clearance for the standard height restrictor units is 4.3m. Larger widths can be accommodated but is subject to a suitable mounting service being available to which the height restrictor top rail can be anchored at one or more points using brackets.
 
Applications and Benefits
 
Height Restrictors have two main functions, doorway opening edge protection and height restriction for prevention of high-level impact damage.
 
For edge protection at the entrance and exit sides of doorway openings the height restrictors are sized to have internal height and width clearance dimensions less than that of the doorway opening to prevent vehicles or loads making contact with the opening edges and causing impact damage. Where doorways are fitted with roller shutter doors the height restrictors ensure that the roller shutter door channels at the doorway sides and the closed door itself at the top of the doorway are protected against costly damage that can be caused by vehicle or load impacts.
 
Where there is a risk of high level impact with overhead pipe bridges, cable trays, air or gas supply lines or ventilation ducts from high vehicles, high vehicle loads or fork lift truck masts the Height Restrictors will prevent disruptive and expensive impact damage as well as warning a vehicle driver that his vehicle or load is too high.
