I received clamps that are designed for well over 2 O.D. hoses versus what was indicated as P/N# 10781-4-22CR max range is 1. As such, I need instead to have purchased 900591B-1C clamps for the appropriate -3 and -4 firesleeve material I need to clamp. Will work with A/C Spruce for return and exchange.
