These are the EWI Tourcase tm Model AU Series rack cases which have an 18.25" rack depth measured from the front rack rails to the rear rack rails and 1" thick closed cell foam padding between the outer case and inner rack shell. The rails are available in 5 heights: 10U (17.5"), 12U (21"), 14U (24.5"), 16U (28"), 18U (31.5") and are drilled and tapped for standard #10 x 32 racking screws. These racks are suitable for all standard 19" wide rack gear.
The AU series side panels are constructed with 3/8 inch hardwood plywood and covered with a black ABS laminate finish. The extrusion is all aluminum and the case is assembled with aluminum rivets. The rivets on the 4 recessed padded flip handles are backed with washers to ensure strength and durability. The cases roll on 4 heavy duty 4" swivel casters, two of which are braking style. The casters are shipped un-mounted with all mounting hardware included.
The case is equipped with two removable lids. Each lid has four heavy duty chromed ball corners and the inside of the AU series lids are fully padded with medium density foam rubber. The lids are secured to the case using 4 recessed butterfly latches per lid. Either lid will fit on either side of the case, right-side up or upside down.
These are well made heavy duty cases manufactured to exacting tolerances and suitable for a variety of racking applications.
