Middle Atlantic rrf12 Rack Rail Pair 12U Steel

Product Description

The MIDDLE ATLANTIC rrf12 is a pair of steel rack rails designed for 19.125-inch wide rough openings in standard equipment rack installations. Each rail is 0.125 inches thick and threaded for 10-32 screws with full hole spacing throughout. At 12U (21 inches) in height, these rails provide a solid mounting surface for rack-mounted equipment. The black powder coat finish resists corrosion and wear in demanding environments. Electricians, AV integrators, and low-voltage installers rely on this hardware when building out equipment racks in utility rooms, server closets, and equipment bays.

These rails are suited for residential and commercial rack installations where 19-inch wide rack frames are standard. The 12U size accommodates equipment panels, patch bays, amplifiers, network switches, and other rack-mount devices. They are intended for installers working with open-frame or enclosed rack enclosures that require field-installed or replacement rail hardware. Sold as a pair, one set covers both the left and right mounting positions for a single rack column.

Compatibility

Installation Notes

Installation is typically performed by low-voltage technicians, electricians, or AV integrators. Ensure the rack frame is de-energized and all equipment is removed before replacing or installing rails. Use a proper 10-32 tap tool if any threads are damaged prior to mounting equipment. Follow the rack manufacturer guidelines for rail seating and fastener torque specifications.
