Clamping/Hanging PVC to top rail of tank

[banditpowdercoat]

I use syicky backs all the time in my job as an electrician. But, I woundlt use the foam backed, self adhesive ones. Not sure what ashesive is on there, or if there is a anti mold agent or whatnot. Just the bare ones with silicone to attach would be a gaeantee safe
