The LINIER 37 Wall Mount Vertical Rail Kit can be installed in either the LINIER Fixed or Swing Out Wall Mount Cabinets to provide a 10-32 tapped rail solution. This tapped rail kit can replace the cage nut style rails that are included with the LINIER Fixed and Swing Out Cabinets for installers who prefer a tapped rail mounting solution. Many installers enjoy the convenience of pre-tapped mounting rails. A tapped mounting rail features holes that contain internal threads. These threaded holes accept rack screws without the need for additional hardware such as cage nuts. This mounting style requires less hardware, and less installation time.
