Product Description

Middle Atlantic RK-RR12 12-space 21-inch rail kit for RK and BRK racks

The RK-RR12 is the 12-space version of Middle Atlantic's RK series threaded rail kit line. At 21 inches long, these rails span 12 rack units of mounting positions, each with 10-32 threaded holes in the EIA standard spacing pattern. The 10-32 thread type eliminates the need for cage nuts, simplifying equipment installation in high-use environments where equipment changes frequently. The heavy-gauge steel provides the rigidity needed for secure equipment mounting in RK and BRK series enclosures. Sold as a pair, the RK-RR12 covers a complete front or rear mounting position. Use as replacement rails or to configure a rack with fresh threaded rails.
