OPTION 2: USB Extender Direct Surface Mounting
(using your own hardware)
The bottom of the Spectra 3022 enclosures features four pre-drilled holes for optional surface mounting.
Distance between the enclosure mounting holes:
42.0mm x 77. 0mm
1. Mark the center point of each of the four holes on your mounting surface either by directly measuring or
using a print out of the stencil below.
2. Hardware recommendation: M3.0 locking washers and M3.0 screws (4 of each per extender) noting
screw length will depend upon thickness of mounting surface.

4. Align the bottom enclosure holes to the newly drilled out holes on the mounting surface.
5. Place a locking washer on each of the four screws and using a screwdriver, fasten the extender into place.
To ensure the stencil below prints to scale be sure to set the page scaling setting to “none”.
