CAB is high strength- they use it for drive up window tubes, environmental sampling machining.
It can be milled and is shatter resistant at most temperatures ( I can attest to driving these into sediment in cold weather they will not shatter)
I can ship individual pieces or lots- wait for invoice if you question what the shipping calculator produces- If it is grossly over I always refund.
There is obviously a difference with 1 piece verse 100, and the larger tubes here are heavy/ bulky when in a large package.
If need be I can create a special listing for you
end caps are available for 50 cents each.
