Conduit “stub-ups” have been traditionally accepted in the concrete construction industry as a necessary evil. Until now, methods of protection and awareness have ranged from spraying the “stub-up” safety orange and taping a flag to them, to setting concrete blocks over the top of the “stub-up”. All the while, the hazards for trips, falls, and expensive damage (or potential loss) of the raceway were only being highlighted or hidden. The concept is to maintain a coupling within the slab or below the grade of concrete to keep future extensions of the conduit from projecting beyond the top of concrete. The plastic sleeve, or pocket former Stub-EASE is attached to the embedded conduit via a threaded coupling, be it set screw or compression connection. This can be accomplished with a 90° bend on the conduit or using a threaded short radius 90° elbow, depending on the depth of the concrete slab. After the concrete pour, the HDPE (high-density polyethylene) sleeve and support is cut down to the top of concrete elevation and left in the slab until the future raceway is ready to be safely extended into a wall cavity. Then, the electrician can use their pliers to unscrew the sleeve, using the plastic partition wall in the middle of the sleeve, to expose the embedded threaded coupling.
