 General
A variety of standard as well as special mounting methods are available to suit virtually any installation.

Standard Mounting Methods

Bosses and Studs (BS)

Bosses (extra pads) are cast onto the back of the plaque. These are drilled and tapped to accept a threaded stud.

Flat-backed plates (generally, smaller sizes) are drilled & tapped for studs without bosses on the back.

Recommended Uses
For concealed, permanent mounting to:

  • Brick walls
  • Stone walls
  • Masonry surfaces

Installation
Drill holes in the mounting surface slightly larger than the diameter of the studs. Fill mounting holes with silicone, epoxy or quickset cement. Set into the holes, and allow the adhesive to cure.

Rosettes and Toggles (RT)

Holes are drilled through the face of the plaque for toggle bolts. Toggle bolts are threaded machine screws 4" to 6" long with spring-loaded butterflies that fold up and pass through wall holes.

Recommended Uses
For semi-permanent mounting to:

  • Hollow tile
  • Cement block
  • Drywall
  • Wood paneling over stud construction

Installation
Using the plaque holes as a template, drill holes through the wall large enough to accommodate the butterfly assembly. Insert each machine screw through the plaque and screw on each butterfly. Fold the butterfly assemblies and insert them through holes until wings spring open inside the hollow wall.

Pull back on each screw head to press the butterfly against the inside wall. Turn each machine screw, first by hand, then with a screwdriver.

If rosette covers are provided, screw rosettes into the toggle bolt heads.

Rosettes, Machine Screws
and Expansion Sleeves (RM)

Holes are drilled through the face of the plaque for machine screws. Each metal expansion sleeve (or lead anchor) has a threaded interior to house a machine screw. The lead anchor will expand when a screw is inserted and tightened.

Recommended Uses
For semi-permanent mounting to:

  • Brick walls
  • Stone walls
  • Masonry surfaces

Installation
Using the plaque holes as a template, drill holes into the wall large enough to accept the lead anchor. Drill deep enough so the fully driven screw won't strike the back of the hole.

Insert expansion sleeves into holes, threaded cones first. Using a metal setting tool, strike tool with hammer to drive sleeve into each hole. Insert each machine screw through the plaque and tighten screws into expansion sleeves with a screwdriver.

If rosette covers are provided, screw rosettes into the machine screw heads.

Wood Screws (WS)

Holes are drilled through the plaque and countersunk to accept a flat head wood screw. Larger sized wood screws, #14 or #16, have the heads drilled and tapped to accept a rosette cover.

Recommended Uses
For semi-permanent mounting to:

  • Wood walls
  • Plaster walls (small plates only)

Installation
Using plaque holes as a template, drill wall holes. Insert wood screws through the plaque holes and tighten screws with a screwdriver.

If rosette covers are provided, screw rosettes into the wood screw head.

Optional Mounting Methods

Invisible Frame (IF)

Angle clips are provided to mount to the wall with standard fasteners, such as toggle bolts, wood screws or machine screws & expansion sleeves.

The cast plaque is then attached to these angle clips with flat head machine screws. These machine screws run through the top and bottom return edges of the plaque.

Invisible Frame mounts require the depth of the plaque to be a minimum of 1-1/4", to accommodate the angle clips.

Recommended uses
For concealed mounting when

  • Plaque may need to be relocated in the future
  • Plaque size is a minimum of 12" x 10"

Brass Rod Stake Mount
Special mounting brackets are cast in place on the back of the casting to accommodate a 24" x 3/8" threaded brass rod. Stake mounts can be angled 45° for positioning plaque at an angle.

Recommended uses

  • Mounting into ground
  • For plaques 12" or less in width
  • Maximum plaque size 12" x 8"

Garden Stake
Bronze stake measuring 24" x 1-1/2" and attached to back of plaque with 10-24 machine screws. Stake is painted to match the background color of the plaque.

Recommended uses

  • Mounting into ground
  • For flat-backed plaques 3/8" thick
  • Maximum plaque size is 12" x 8" for 1 stake or 20" x 8" for 2 stakes.

Integral Post Cap Mount
A post cap is a decorative sleeve cast integral with the bottom of a plaque to mount onto a round post. Post caps are available in several standard designs to accommodate 1-1/2" or 2" diameter post mounts.

Recommended uses

  • Freestanding installation into the ground on a single post
  • For plaques greater than 12" in width
  • For double-faced plaques with copy on both sides

Curved Plaques
Matthews can roll a bronze or aluminum plaque to fit a curved wall installation. Provide the diameter, radius or circumference of the curved surface.

Parameters for usage

  • Maximum size of plaque 96" wide x 60" high
  • Flat backed castings, 1/4" or 3/8" thick
  • Border design must be flat (Straight Edge, Single Line or Double Line)
  • Mounting holes through the face are highly recommended.

Rosettes
Rosettes are decorative elements used to cover the screw heads on a plaque installation. Rosettes can also be used with other materials to accent architectural décor.

All Matthews rosettes (except R77) are available in cast bronze, brass or aluminum. Rosettes marked with an asterisk (*) are standard---all others are available as an option.
