Description:

Rack or Cabinet Adapter Set โ€” 23″ to 19″ โ€” 3U

The 23-inch to 19-inch rack adapter set (3U) allows standard 19-inch rack mount equipment to be installed in legacy 23-inch racks or cabinets. These rack conversion brackets are widely used in telecom facilities, central offices, broadcast racks, and industrial equipment enclosures where 23โ€ณ infrastructure remains in service.

Manufactured in the USA from premium 16-gauge steel, these adapters are finished with a durable satin-black powder coating to ensure long-term durability in demanding data center and telecom environments.

10-32 PEM nuts are inserted on one side of the adapters with EIA-spaced mounting slots. The PEM-nut to slot spacing dimension is 2.75″, ensuring proper alignment when converting 23-inch rack rails to standard 19-inch equipment mounting.

Why These Fail
  • Legacy telecom racks use 23-inch rail spacing incompatible with modern 19โ€ณ equipment.
  • Improvised mounting methods can cause misalignment and rack stress.
  • Low-quality adapters may bend under heavy servers, switches, or UPS equipment.
  • Incorrect hole spacing prevents proper EIA rack alignment.
Our Solution
  • Heavy-duty 16-gauge steel โ€” supports telecom, network, and server hardware.
  • Precision EIA spacing โ€” ensures proper mounting alignment.
  • Integrated PEM nuts โ€” threaded mounting built directly into the bracket.
  • Accurate rack conversion โ€” converts 23โ€ณ rack spacing to 19โ€ณ equipment mounting.
  • Durable powder-coat finish โ€” corrosion-resistant and professional appearance.
  • Made in the USA โ€” built for professional telecom and data center installations.

Each pair of adapters is boxed and includes two types of EIA-style mounting hardware:

  • 8) 12-24 Black Panhead Dog-Point Phillips rack screws
  • 8) 10-32 Black Panhead Dog-Point Phillips rack screws

5U 5 8.75โ€ณ 22.23 cm
8U 8 14.00โ€ณ 35.56 cm

Maintenance Tip: Multiply the rack unit size (U) by 1.75 to determine rack height in inches (1 inch = 2.54 cm). Example: 5U ร— 1.75โ€ณ = 8.75โ€ณ โ‰ˆ 22.23 cm.
