Rotary File Cabinet Starter Unit, Letter, 7 Shelves, Bone White This Rotary File saves time, space and money. The innovative design includes a double-sided, rotating shelf unit that houses more than twice the files in less space than a traditional filing system while providing fast and easy access to stored materials. Specifications: Base: The Ez2 base is formed out of 13 gauge steel with 13 gauges steel-formed U-Channel reinforcements. These 13 gauge steel channels have a 4" wide x 3-1/2" deep cross-section and run the full length and width of the base. These channels are mig welded to the base forming a rigid structure capable of supporting the weight of the cabinet. At each corner, a welded steel 11 gauge gusset adds strength and rigidity to the base. Four adjustable leveling feet allow the base to be leveled from the top of the base. The base mechanism provides 90 indexing of the rotary file cabinet. The base does not require the use of a foot pedal to index the cabinet. Uprights and Locks: Each Ez2 unit has (4) upright posts with dual durometer PVC closing strips. The posts are made from 11 gauge steel and are bolted directly to the unit base with (2) 1/4" - 20 flat head bolts per post. A lock assembly and locking rod is supplied with each unit and is conveniently located on the right front post. All cabinets are random-keyed. Lock bar is formed from 3/8" diameter steel rod for maximum durability. Locks have field removable core for easy key changes. Locks can be installed on both sides of unit. Unit can be locked in the open or closed position. Rotary Bottom: The Ez2 rotary bottom rides on top of the base and is fully supported by 5/8" diameter, hardened steel ball bearings. The letter size unit has a 19-1/4" diameter bearing cage with 22 each, 5/8" diameter ball bearings. The legal size unit has a 24" diameter bearing cage with 44 each 5/8" diameter ball bearings. The rotor bottom pivots on a 3/4" diameter pin and a mating steel brushing, that is mig welded to the underside of the rotor shelf. The rotor bottom is constructed by mig welding and spot welding an 11 gauge steel bottom support plate to an 18 gauge steel top. Two (2) each 14 gauge steel reinforcement angles are sandwiched between and support the full length of the top and bottom plates. The 90 index indentation is formed on the bottom support plate. Slots in 1" centers are punched on top of the rotary bottom to accept dividers. Center Panels: A structural center panel is provided with each rotary file unit. The 13-1/2" high, 16 gauge steel panel is bolted to the inner flange of the doors for outstanding cabinet strength. Rotary Side Panels: Each 3-piece rotary side panel is formed for maximum strength and rigidity. The outer panel is formed from 20 gauge steel and is beveled on each leading edge for superior post clearance. The 18 gauge inner panel is spot welded to the outer panel for high load carrying capacity. The inner door panel has holes on 1/2" center to support and provide vertical height adjustment of accessories. End Panels: The end panels complete the unit and are formed from 18 gauge cold rolled steel. The end panel bolts directly to the unit posts and converts an adder unit to a starter unit. The end panels are connected to the unit with a keyhole system that allows panels to be installed by 1 person. Rotary Top: The 20 gauge steel rotary top is formed for strength and is bolted to the side panels. The rotary top has a 3/4" diameter welded pivot pin. Canopy Top: Formed and welded for rigidity and strength, the 18 gauge canopy top is mechanically fastened to each post. The 1" I.D. steel bushing that mates with the rotary top pivot pin is mig welded to an 11 gauge steel plate. The bushing plate is spot welded to the center of the canopy top. Shelf:.
