Greg,
Can’t you use some like the Tolco 22L2 with a ¼” HDI-P? Typical on our post tension jobs we are using presets with rod and ring.

Points of interest: 1) removing the bonnet from a hang ring voids the listing. 2) Hanger rings without the bonnet (from the factory) are not listed for cpvc 3) One hole straps cannot be used to hang pipe upside down from the slab. 4) Two hole straps cannot be attached with 3/8" bolts or rods without modification to the hole size - which voids the listing. 5) Two hole straps cannot be hung with powder driving pins in post tension slabs because there is a max hanger depth of 3/4" - the highest rating we found was exactly 125 lbs...so even with 2 of them you do not meet the "250 lbs plus 5x the weight of the water filled pipe" requirement. It would seem that we are well behind the times in addressing this issue as an industry. Just noting....
