Hang-A-Plan filing systems allow large amounts of plans & drawings to be well organized & easily accessed using only a minimal amount of storage space. Hang-A-Plan systems offer a range of Australian made mobile trolleys, wall racks & plan binders to accommodate A0, B1, A1, A2, A3 & A4 size plans & drawings. There are many trolley & binder options to suite different budgets & user requirements. Hang-A-Plan binders are the heart of the filing system. The binders have a strong super-continuous aluminium clamp which holds the plans securely & firmly together for storage on a Trolley or Wall Rack. Hang-A-Plan binders feature a 3-piece clamp design for a strong & even grip & a centred handle for better load balance & carry comfort. This Premium trolley has a 25 binder capacity & features a fifth wheel for enhanced mobility & increased load capacity. Available in two sizes; a large trolley for up to A0 size binders & a smaller trolley for up to A1 size binders. A separate steel ' Systems Shelf' is available for premium trolleys. This add-on shelf provides extra storage space above the trolley for associated files.
