The SRW18UHD is a SmartRack heavy-duty side-mount wall-mount rack Enclosure Cabinet that can accommodate full server depth equipment (29 to 31-inch) but only protrudes off the wall 24-inch. Since the equipment is mounted in the wall cabinet sideways, the leverage off the wall is less and the weight capacity is increased greatly. Access to mounted equipment is still great due to full access doors on each side of the cabinet (for front and rear equipment access) and one full removable side panel for access along the length of the mounted equipment. Adjustable front and rear mounting rails have square holes (default position) and tapped holes to accommodate 18U of equipment.
