The APC 0M-756H Rev 12 Sliding Rack Rail Kit is a four-post, rack-mount rail system designed to install Smart-UPS units into standard 19-inch, four-post enclosures. Known as OM-756H Rev 12, this kit provides sliding rails that accommodate varying enclosure depths and is specified to support UPS equipment in the 65–230 lb range. Designed for four-post racks, it pairs with APC Smart-UPS units to provide a secure, compliant mounting solution in standard 19-inch enclosures. The Rev 12 designation distinguishes this version of the OM-756H rail kit, and installers should verify compatibility with both the UPS model and the enclosure to ensure proper fit.
