So, I don't use Hanley (I think that's what you meant), typically use principal tapouts. But another product we have started to use is everylite, sold by Reece, it's a box of modules that snap onto something like 1/2" tubing, so you can blindly buy a box and some sticks and retrofit random sizes as needed, just have to cut the tube, snap the modules on, and wire. Problem there is the tube doesn't fit in the sockets, you have to add something like angle to mount to. Saves a lot of time waiting for the right size sticks to show up.
Anyway, if the Hanleys are a true 'in socket' retro solution, they will likely work fine. It's grimco's house brand, so it's not the worst and not the best.
