If you have a crack in a masonry or plaster wall and want to monitor if this crack is widening or not, this item is for you.

This lot consists of 1 Flat type Crack Monitor in sealed plastic pouch. Included in this lot free of charge is one Epoxy Pouch and 2 stainless steel Caliper Marks. 

The epoxy pouch although have been in storage for several years, they are soft to touch and I used one to cement something else and found it to be in excellent usable condition. I am offering it free of charge

The Caliper Marks are 1/4 inch round in size. They should be glued by using epoxy cement to both sides of a crack in a masonry wall, and by using a caliper, you can monitor and log the change in the crack size. (see photos) There is no charge for these Caliper Marks either!

I have 4 sets of these available for sale.
