There are many among my relatives and friends who are working in the engineering field. Most of them work overseas and their jobs include being in a construction and mechanical-related works. I always find it fascinating every time I look at their photos at Facebook as they are handling somewhat complicated materials like machinery and equipment. For sure, they also have USDA approved levelers as one of their tools in building and construction.

Such is but a thing for man. I am not familiar with it, but when I asked the husband about its use, he let me understand that one of its basic use is for mounting equipment. Which is but a foreign thing to me still! Lol.
