    Ferguson stocks them in their DC's (ProFlo branded, less expensive than the big names.)

    Johnstone Supply, probably SupplyHouse online.
    The refrigeration suppliers have them down to 1/4 cts size if you want to mount remote air vent lines :)

    Thanks guys!

    @hot rod
    Yes indeed! Those remote air vent lines are important with you have air vents on top of those big storage tanks. Every vent leaks sooner or later.

    I buy from FW Webb as well. We use them extensively on all refrigeration, they are listed by tube OD, so 3/4 cts is referred to as 7/8 cushion strut clamp 1/2 cts is 5/8 cushion clamp etc.

    You can choose to do what you want, but you cannot choose the consequences.

    Air vents above boilers can be a big problem also. They tend to leak down into the most expensive components, control boards, fan motor controls, etc. That is where a vent tube has some real value.

    Getting back to strut clamps, I'd like to see a good way to insulate them. We just stop the insulation at the unistrut.
    8.33 lbs./gal. x 60 min./hr. x 20°ΔT = 10,000 BTU's/hour

    Two btu per sq ft for degree difference for a slab

    I have a United Refrigeration close by. It's a satellite branch. Never seen them on the shelf but i guess ill have to ask them. Supplyhouse.com I guess would be an option as well.

    RE Michel can get for you if they're not on there self.

    Aireco in Winchester has them too. Probably about an hour from you?

    If you go with a bigger clamp and wrap tape around where the clamp goes, just let the closed cell pass through it. Obviously, it won't grip it as tightly, but usually that's not an issue.

    Winchester is a little bit far to go for clamps.
