Over this summer at my families cottage someone stole the condenser. So I thought I would make it a little harder for some one to snatch and grab this one. I started with a 8 inch concrete pad, bolted from the inside of unit. Then welded a 1inch square base with 3/4 pegs bolted that to the concrete then welded the blots on site. Made the cage slip on to the 3/4 pegs and finished with a stainless lock for the cage and the disconnect. 1/6 steel plate over the cage lock, to protect lock. Color match carrier colors then tapped a carrier nomenclature on the front. Graded the soil away from unit with native soil, then topped it off with 1/2 top soil and patch master for a reseeding. Not saying no one could steel it, but its just a little easier to go to the next house and take that one.
