Overview

The Extron® SMA-1 swivel mount adapter kit is used with an SMB 303 box for tabletop installation of Extron devices. The

assembly can be rotated up to approximately 180° in either direction from a starting reference point. The angle can be set

by the user.

SMA-1 Parts

The five component parts of the SMA-1 (see the figure to the right) are

preassembled for shipping:

z Locking nut

z Backing plate

z Hex key

z Snakeskin wire cover

Getting Started

Choose a location for mounting the SMA-1. The installation site must be free of obstructions above and below the table. If

the SMB 303 box is mounted with the SMA-1, the box must also be able to rotate as desired.

Securing the Base of the SMA-1 to the Table

1. Use the cut-out template (provided) to mark the position of the SMA-1.

2. Drill a hole through the table that is 1 inch (2.54 cm) in diameter to accommodate cables.

3. On the cut-out template, mark the stopping points and the reference point.

NOTES: The reference point indicates the direction in which the mounted device faces at rest. The stopping points

Rotate the template until a suitable combination of stopping points aligns with the reference point.

There are many possible combinations of stopping points. Figure 1 (below) shows three of the most common

setups.

One stopping point allows

assembly to rotate 180°

in either direction.

5. Drill two pilot holes for the mounting screws (provided).

6. Disassemble the SMA-1 by undoing the locking nut and removing the

remaining parts from the conduit.

7. Place the conduit (with base) over the cable hole, with the tooth pointing in

the direction of the reference point.

8. Place the insulation disk over the conduit.

9. Place the swivel disk over the insulation disk so that the mounting holes align

with the pilot holes drilled in step 5.

10. Secure the swivel disk to the table using two screws through the mounting

holes.

Attaching a Mounting Box

Figure 3 shows how to mount the SMB-303.

1. If necessary, remove any devices that are

mounted in the box.

2. Place the base of the box over the conduit and

align it so that the front of the box faces the

reference point.

3. Place the backing plate over the conduit so

that it sits on the floor of the mounting box.

6. Run cables and mount a device in the

mounting box, as described in the user guides

for the box and the installed device. These

guides can be downloaded from the Extron

website (www.extron.com).
