OPTION 2: USB Extender Direct Surface Mounting
(using your own hardware)
The bottom of the Starling 3251C enclosure features four pre-
drilled holes for optional direct surface mounting. Using the
stencil below, along with your own hardware you can directly
mount your USB Extender on a surface.
Distance between the enclosure mounting holes:
42.00
x
33.70mm
1. Mark the center point of each of the four holes on your mounting surface either by directly measuring or
using a printout of the stencil below.
2. Hardware recommendation: M2.5 locking washers and M2.5 screws (4 of each per extender) noting
screw length will depend upon thickness of mounting surface.
3. Drill through each of the four-hole markings on the mounting surface using a 3.70mm (0.1457”) drill bit.
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”.

4 Slots for Mounting
The bottom of the Starling 3251C enclosure also features four
convenient slots for cable mounting. Simply thread a cable
tie, (also called tie-wrap or zip tie), into the mounting slot and
through the cable tie head and secure it to a pole or other
surface by pulling it tight. Cable ties are not included with this
system due to varying lengths dependent upon the application.
