NSTALLATION

  Tools (not included)—Drill, screwdriver (Phillips or 

standard), and either of the following:
•  Three #8 (4mm) pan head machine bolts with matching 

nuts and washers and a 5/32” (5mm) drill bit.

•  Three #8 pan head self-tapping screws and an 

appropriately-sized drill bit for drilling starter holes.

1.  Using the swivel base as a template, mark the location of 

the three holes that are used to secure the bracket to the 

mounting surface.

2.  Drill the mounting holes.

•  If securing the base with machine bolts, drill three 5/32” 

(5mm) holes at the locations you marked.

•  If securing the base with self-tapping screws, drill starter 

holes at the locations you marked. Starter holes should 

generally be no deeper than half the screw length.

3.  Secure the swivel base with three bolts or screws. DO NOT 

OVERTIGHTEN.

4.  Place the rest of the mount over the swivel base and secure 

with the short knob.

                 

The swivel base is designed to be secured using a pan head screw 

or machine bolt. If you use a screw with a countersunk head, you risk 

damaging the mounting bracket.

Secure the base and attach the mount.
