Mounting the eHorn without the Brackets
To mount the eHorn directly to the mounting surface:
1. Using the template included with the eHorn (doc. no
25500239), scribe the centers of the six mounting holes on
the mounting surface.
NOTE: For most applications, only four outer mounting
points are necessary.
2. Drill a 9/32 in hole at each of the four scribe marks.
3. Secure the eHorn from behind the surface with the installer‑
supplied 1/4 in x 20 screws. Choose an appropriate length
fastener. Note that the threads in the cover have a depth
of 0.5 in.
