Does anyone know where to purchase about ten feet of each of these. I don't need a 100 ft roll. Thanks
Just about any company that sells and services industrial instrumentation in your area would have it. Most would be happy to cut the lengths you need - and add their normal percentage to the price.
If we had the need for only a small amount we'd call these guys:
