Mounting methods for National Register Plaques

FINISHED DIMENSIONS - Bronze plaques are cast from molten metal. As such, the finished dimensions WILL vary from the actual dimension ordered. Typically, the metal can shrink 1/16" over any 12" dimension. This means that a 24" by 24" plaque can vary in size from 24" by 24" plus or minus 1/4" - possibly more.

You should always wait until you have the actual plaque in your hands BEFORE you build any custom mount. If this is not possible, you must allow sufficient room around the plaque to accommodate differing dimensions. If you will mount the plaque in concrete, allow enough room and plan on filling it with a grout. If mounting on a raised monument, allow sufficient room and plan on centering the plaque.

Plaques with either dimension 4" and under will be drilled for 2 holes.

Recessed back plaque

The image on the left shows the cross section of a large plaque. The back is recessed to reduce weight.

The image on the right shows the cross section of a small plaque. It is solid.

The type of back on your plaque will depend upon the size of the plaque. We reserve the right to determine the type of back during the casting process.

BOSS AND STUD

BOSS & STUD - PREFERRED METHOD FOR MOST NATIONAL REGISTER PLAQUES

Drilled and tapped bosses on back of plate. Threaded studs for concealed mounting to brick, stone or cement. Flat backed plaques do not have bosses - they have drilled and tapped holes.

HOW-TO-DO-IT

  1. Screw studs into threaded bosses (threaded holes) in back of the plaque.
  2. Using studs to locate points on mounting surface, drill holes in mounting surface slightly larger than threaded stud.
  3. If wall is solid such as cement or brick;
    1. Discard washers and nuts. Fill holes using 'Liquid Nails', 'Epoxy' or other permanent mastic.
    2. Push studs into the holes and anchor plaque until mastic hardens.
  4. If you can get to the back of the wall;
    1. Insert studs through holes and have it held in place.
    2. From the rear, place washers on studs and secure with nut
MACHINE SCREWS AND EXPANSION SLEEVES

MACHINE SCREWS & EXPANSION SLEEVES

Expansion sleeves for mounting to brick, stone or cement with optional rosette covers.

HOW-TO-DO-IT

  1. Using holes in plaque to locate points on mounting surface, drill holes in mounting surface to accommodate expansion sleeve.
  2. Insert expansion sleeves into all holes.
  3. Insert screws through plaque and fasten into expansion sleeves.
  4. Screw on decorative rosette
MACHINE SCREWS AND TOGGLE BOLTS

MACHINE SCREWS & TOGGLE BOLTS

Toggle bolts for hollow wall installation with optional rosette covers.

HOW-TO-DO-IT

  1. Using holes in plaque to locate points on mounting surface, drill holes in mounting surface to accommodate toggle bolts.
  2. Insert machine screws through plaque and screw toggle bolts onto machine screws.
  3. Tighten machine screws.
  4. Screw on decorative rosette.
ROSETTES AND WOOD SCREWS

ROSETTES & WOOD SCREWS

Wood screws for mounting to wood surfaces. Can also use optional rosette covers.

HOW-TO-DO-IT

  1. Using holes in plaque to locate points on mounting surface, drill pilot holes in mounting surface if desired.
  2. Insert screws through plaque and tighten.
  3. Screw on decorative rosette
