Well cap
Fit perfect looks great. I have another well that I’m going to pull up and will buy it again.

Bolts are close to drop hole
Had to return as the bolts were too close to the drop hole for me to fit a galvanized T in-between them. Otherwise solid construction.

Quality. Would recommend replacing bolts with SS if you want to do it once.
Typical Merrill high quality. No issues. The nuts on the bottom side are not captive. I would suggest replacing the bolts with stainless steel bolts and nuts. If you want to do it extra right, then get some nylock nuts or glue the nuts into the recessed housing on the bottom side.
