1] Mount the Speaker Plate. Determine if you will be mounting the speaker to the Wall/Speaker Plate (a) or the Satellite Speaker
Adapter (d). Speakers with dual threaded inserts on the back and small wood speakers without threaded inserts will require the
Wall/Speaker Plate. Speakers with single threaded inserts or heyhole mounting will require the Satellite Speaker Adapter.
Note: This mount is designed to accommodate a large variety of speakers. Not all parts will be used.
A] Mounting to the Wall/Speaker Plate (a)
- Threaded Inserts: Mount the Wall/Speaker Plate (a) to the speaker
using the appropriate bolts. 1/4 - 20 x 1/2” Machine Screws (k) are provided.
Other sizes are available at most hardware stores.

- No Threaded Inserts: Use the Wall/Speaker Plate as a template to
mark hole locations on each speaker. Pre-drill pilot holes with a 1/8” bit.
WARNING: Be careful not to drill all the way through the
cabinet and into components inside. Sanus is not responsible
for any damage caused by drilling into the speaker.
B] Mounting to the Satellite Speaker Adaptor (d)
- Threaded Insert: Mount the Satellite Speaker Adpter (d) to the speaker using the appropriate bolt. 1/4 - 20 x 1/2”
(k), 1/4 - 20 x 7/8” (l), 8 - 32 x 5/8” (o) and M5 x 20mm (m) are provided. Other sizes are available at most hardware stores.
Note: Some Bose speakers will require the M4 x 8mm Flat Head machine Screw (q). Attach the screw through the
off set hole on the face of the Satellite Speaker Adapter.
- Keyhole: Mount the Satellite Speaker Adapter (d) to the speaker by placing a Plastic Spacer (n) onto an 8 -32 x 5/8”
Machine Screw (o). Next, place the machine screw with the spacer through the Satellite Speaker Adapter. Then start to thread
the 8 - 32 Keyhole Nut (p) onto the machine screw with the teeth facing the Satellite Speaker Adapter. Insert the nut into the
keyhole on the speaker. The teeth on the nut should make contact with the speaker cabinet enabling you to tighten the bolt.

2] Mount the Wall Plate. Determine if you will be mounting the wall plate to a stud, hollow wall, or concrete wall.
Warning: This step is critical for safety. Improper installation may result in damage or injury. Contact Sanus or a
professional AV contractor if you have any questions about this procedure or your specific finished installation.
A] Mounting to a stud. Use a high quality stud sensor to locate the center of the stud. Mark each edge of the stud with
a pencil. It is a good idea to accurately verify where the stud is located with an awl or thin nail. Use the Wall/Speaker
plate (a) as a template to mark hole locations with a pencil. Verify that the hole locations are vertically aligned over
the center of the stud. Use an 1/8” drill bit to drill two pilot holes. Drill the holes at least 1 1/2” deep. Mount the wall
plate using the #12 x 1 3/4” Self Tapping screws (h). The wall plate should now be securely mounted.
Warning: The mounting screws must make contact with the center of the stud to provide adequate
support. If the mounting screws only engage the edge of the stud, injury or damage may occur.
B] Mounting to a hollow wall. Use the Wall/Speaker plate (a) as a template to mark hole locations with a pencil.
Verify that the hole locations are vertically aligned and use a 1/4” drill bit to drill two pilot holes. Gently tap the
anchors (i) into the pilot holes until each anchor is flush with the wall. Mount the wall plate using #12 x 1 3/4” Self
Tapping screws (h). The wall plate should now be securely mounted.
C] Mounting to concrete or cinder block. Use the Wall/Speaker plate (a) as a template to mark hole locations with a
pencil. Use a 5/16” mason bit to drill two pilot holes. Drill the holes at least 1 3/4” deep. Gently tap the anchors (i) into
the pilot holes until each anchor is flush with the wall. Mount the Wall/Speaker plate using #12 x 1 3/4” Self Tapping
screws (h). The wall plate should now be securely mounted.
3] Final Assembly.
A] Place the Wall/Speaker Plate Hardware Covers (e) onto the Wall/Speaker Plates (a).
B] If you are using the Ceiling Extension (b) place it onto the Wall/Speaker Plate next. Tighten the allen set screw until
it is snug. If you are not using the Ceiling Extension skip to step C.
Warning: Do not overtighten! Continuing to tighten the allen set screw once it is snug will not make the
connection stronger.

C] Put the Arm Assembly into place and tighten the allen set screw until it is snug.
Warning: Do not overtighten! Continuing to tighten the allen set screw once it is snug will not make the
connection stronger.
D] Remove the Arm Assembly Hardware Covers (f). Use the allen key to loosen the bolt. Adjust the angle of the Arm
Assembly to the desired position and retighten the bolt.
Warning: Adjusting the angle of the Arm Assembly without loosening the bolt will reduce the ablility of
the bracket to maintain itʼs position over time.
E] Replace the Arm Assembly Hardware Covers.
Note: There is one angled surface on both the Arm Assembly and the Hardware Cover. These surfaces should
be aligned.
