When are cup anchors installed?

When are Cup anchors installed in the construction of the pool.

My gunite guys are telling me the plaster guys will do it. Is this true? Do the gunite guys need to do anything special?

What are those used for? The rope to separate deep from shallow?

the 14-507 are the typical cup anchors installed, they look nicer and don't stand out at apose to those others that you have up there, The plaster guys can put them in, just make sure that there are holes where they will be installed. also that they are infront of one another, and atleast 1 1/2 inch underneath your tile line, also when installed to make sure that they will be flush with the plaster, almost a even line with the tile for a perfect,smooth fit.

You can use them for that. I plan on securing a thermometer to one of them.
