MR and MR D Series Installation Guide

This guide provides procedures for installing and modifying the Extron MR (standard) and MR D (Decora®) series plastic mounting brackets (mud rings).

Each mud ring kit includes an expansion kit consisting of two small top/bottom segments that allow the bracket to be enlarged or reduced to the next larger or

Determining the installation location

The UL-listed MR series mud rings do not need to be fastened to wall studs, so they can be placed almost anywhere on a wall or other mounting surface. When you are deciding where to install the device and mud ring, consider the placement of the cable(s) and access. You may need to install the cables before you install the bracket.

NThe mud rings fit properly in hollow wall thicknesses ranging from 1/4" (0.63 cm) to 1” (2.5 cm).

WThe MR series mud rings are UL-listed for low-voltage applications only.

Preparing the site and installing the mud ring using the doglegs

1.See the to-scale cutout template included with the mud ring to determine the cutout dimensions for your mud ring. Tear the cutout template along the perforations for the appropriate mud ring size.

2.Place the template against the surface to be cut, using a level, if necessary, to keep the template even. Trace around the template.

3.Carefully cut away the mounting surface material inside the traced template lines.

4.Test the fit of the mud ring. The doglegs should fit easily into the hole and the flat portion should rest flush against the wall. See the note in figure 2, at right.

5.Rotate all doglegs inward.

6. Insert the mud ring into the hole.

7.Tighten all of the dogleg screws until the doglegs clamp the mud ring to the mounting surface. Do not overtighten.

Standard mud rings only: If you are going to screw the mud ring to the surface, rather than using the detachable doglegs, mark the four surface mounting screw holes at the corners of the mud ring. See figure 2, at right.

Rotate doglegs and insert mud ring into wall opening.

NOTE Do not disassemble the dogleg from the dogleg screw. Rotate the dogleg out of the way to insert the mud ring into the wall.
