These robust & versatile free standing modular frames are supplied with fully adjustable leg assemblies and 500 x 500mm polypropylene feet, which incorporates anti-vibration rubber mats adhered to the underside. Robust 50 x 50mm box end bars and cross bars both being 5mm thick in section, cater for picking up the point load mid span, resulting in even load dispersal through the framework down to the feet. The optional adjuster plate can also be purchased and these are supplied with fixings. Application: Suitable for heavier building services such as large air handling units, chillers and packaged plantrooms. Quads are particularly useful for managing heavy loads, and as a direct replacement for traditional concrete plinths, as they can be re-positioned to accommodate late design changes.
