Using pre casted coping stone

[t56tr]

I’m using precast concrete coping, upstate NY. Steel wall vinyl liner. Coping is about 1.5” thick. I’m being told by the manufacturer to pour a collar around the whole perimeter 5-8” thick (top perimeter). It’s seems like alot of work for that. Is that necessary? Basically from what I understand the coping sits 1/3 on top of the Steel wall (with some type of bonding agent, or mortar, silicone etc) and the other 2/3 sit on the collar pour. The pool is getting back filled w stone and the patio is going to be normal 3-4” broom finish concrete (which butts up against the coping). Is there a more economical way to do my coping than described?

I posted the same question just a couple of days ago. Check it out: Coping stone underbed thickness?

If you search around the internet, you'll see everything from 2" to min 6" with rebar (Unilock's recommendation). In my case, I've backfilled with 3/4 gravel that's gone through winter now, and I have high confidence that 2" of concrete will suffice.
