Mounting Bronze Plaques on a back post

 

By continuing, you agree you have read and agree to the disclaimer

 

When you order a bronze plaque and a back post, we cast a special pad on the back of the plaque AND we provide a back post of the proper size to hold the weight of the plaque you have purchased. On smaller (lighter) plaques, a pad may not be needed and we drill and tap the mounting holes directly into the back of the plaque.

 


Back post mounts come in either a 30 degree bent top (top image) to display the plaque at an angle or a straight top (bottom image) to display the plaque vertically.

To assure proper sizing, back posts are provided in the following standard sizes;

  • 3/4" square - 48" long for plaques up to 100 square inches
  • 1" square - 60" long for plaques 80 to 250 square inches
  • 1-1/2" square - 80" long for plaques 200 to 450 square inches
  • 2" square - 80" long for plaques over 450 square inches

During the pattern making process, the cast plaque is provided with a special pad for mounting of the back post or on smaller plaques, the back of the plaque is drilled and threaded.

When mounting the back post, you will need a wrench. Either a box wrench or ratchet wrench works fine.

N.B. - Be very very careful not to over tighten the bolts. Bronze is a soft alloy (it is 88% copper). It is VERY easy to strip the threads in the back of the plaque. You may wish to use a thread locking material on the threads before installing them.

The bolts (provided by us) are then inserted through the pre-drilled holes in the post and threaded into the special mounting pad cast as part of the plaque, and tightened.

These images were taken on the foundry floor. During actual installation, we recommend cutting the back post to the desired length, then setting the back post FIRST - usually in concrete - and then with the aid of an assistant, attaching the plaque to the post. REMEMBER - the post must be plumb in both directions (front to back and side to side).
