Metal Decora® Mounting Brackets Installation
Guide

The Extron metal Decora mounting brackets (mud rings) are used to mount Extron
products onto a variety of surfaces, including drywall, particle board, wood, metal,
and other thin wall applications. These mud rings fit under Decora wall plates and
can be applied to surfaces with thicknesses from 3/8" to 1¼". The brackets are
available in one-, two-, three-, and four-gang sizes; in black only.

This guide gives an overview of how to install the metal Decora mud rings.

Determining the Installation Location

The metal Decora mounting brackets do not require attachment to wall studs, so
they can be placed almost anywhere on a wall. When you determine where to
install the device and mounting bracket, consider cable placement and access. You
may need to install the cables before installing the bracket.

Preparing the Installation Site

1. Refer to the appropriate template diagram (later in this guide) to find out the
dimensions of the opening required for the size and type of mounting bracket
that you have.

2. Using a ruler or tape measure and a soft pencil, draw guidelines on the
installation surface (wall or furniture) in the desired orientation and location
where the opening for the bracket will be cut.

CAUTION

3. Use a jigsaw or small hand saw to carefully cut away the material within the
guidelines that you drew.

4. Check the size of the opening by laying the mounting bracket against it. The
flat portion of the bracket should lie snugly on the wall or furniture surface,
and the tabs through which the screws will be inserted should fit easily into
the opening. There should not be noticeable play within the opening.

The template diagrams in this guide are not full size. Do not trace
them or use them as patterns on the installation surface. Use these

diagrams only for reference to obtain the dimensions of the hole that needs
to be cut for your bracket. Use a ruler to measure and draw the cutting
guidelines.

Installing the Mounting Bracket

To mount the metal Decora mounting bracket,

1. Pass 1¼" (3.18 cm) long or ¾" (1.90 cm) #6-32 machine screws (provided)
through the largest holes in the mounting bracket, then through the smaller
holes in the two tabs behind the bracket. Use the shortest screw needed.

On the one- and two-gang brackets (which have two tabs), insert two screws
through the two large holes in opposite corners. On the three- and four-gang
brackets (which have four tabs), insert four screws through the large holes in
all four corners.

2. Loosely fasten (using 2-3 turns) the backing clip on each screw.

3. Insert the mounting bracket into the opening in the surface.

4. Rotate each clip so that the tab is behind the surface to hold the bracket

snugly in place when the screw is tightened. See Detail A and Detail B, in the
figure on the next page.
