Heavy Duty Columns provide a thicker steel frame than usual mounting columns, to offer greater security and durability. When combined with a TOP-TEC ceiling plate and security device, they provide a key component for suspending and securing AV equipment. Each Heavy Duty Column up to the length of 2000mm is approved to Loss Prevention Certificate Board (LPCB) standards when tested under attack conditions. Although LPCB do not approve columns of 2000mm or greater, we provide these sizes and others in the same design, to cater for different ceiling heights.
