The new ENT Support Unit (ESU) is designed to raise the tubing or conduit up off the concrete form during the concrete pour maintaining a level raceway. With its minimal surface contact, the ESU allows for maximum aggregate flow and concrete consolidation. Easy to use, the ESU snaps around any size of ENT from 1/2" to 2". It is perfect for use in high rise buildings constructed with posttensioned (PT) concrete slabs. In PT construction, the reinforcing rebar is spaced far apart requiring the ENT to be supported every 2 to 3 feet.
