Standard Server Rack

Which shelf would work best in my server cabinet? The general rule of thumb is to measure 6” shorter than depth of cabinet for all 4-post cabinets. This measurement will compute the optimal shelf depth for your particular cabinet enclosure. Also, please take into consideration that rails are often set at a distance less then the actual depth of the internal dimension.

	Solid Flat Shelf - Sometimes called a stationary or fixed rack shelf, a flat shelf mounts to all 4 mounting rails of a 4-Post Server Rack / Electronic Enclosure. Due to its simplicity, Flat Shelves will often occupy less than 1U of rack space. Weight Limit: 150 lbs.
	Adjustable Shelf - Similar looking to a flat shelf, Adjustable Shelves attach to all 4 mounting rails of a 4-Post Server Rack / LAN Enclosure. The main difference between the two is the rear mounting ears for the Adjustable Shelf are adjustable by 4" less than the shelf depth and 4" more than the shelf depth. For example, an 18" Adjustable Shelf can mount on posts ranging from 14"-22" deep. Weight Limit: 150 lb s..
	Heavy Duty Vented Shelf - Heavy Duty shelves are constructed in a special manner in order to accommodate particular mounting needs. Heavy Duty shelves occupy a full 1U (1.75”) of rack space and will support a weight up to 300 lbs. Heavy Duty shelves attach to all 4 mounting rails of a 4-post server rack. Weight Limit: 300 lbs.
	Sliding Keyboard Shelf - This specialty shelf is designed to accommodate rack optimized keyboards. The Sliding Keyboard shelf attaches to all 4 mounting rails of a 4-post server rack enclosure. Weight Limit: 75 lbs.
	Vented Flat Shelf - Ventilated Shelves are equal to standard shelves, though, ventilation slots provide additional air circulation between rack units. Ventilation Shelves mount to all 4 rails of a 4-post server cabinet. Weight Limit: 150 lbs.
	Sliding Pullout Shelf - Pullout shelves are useful for positioning non-rack mountable equipment in a server rack which needs frequent access. Sliding Pullout Shelves mount to all 4 mounting rails of a 4-post server rack. Weight Limit: 150 lbs.
