OCM, Incs Concrete Sleeves are used commonly on high rise structures to create a vertical pass-through void for piping and conduit.

They are injection molded from high strength, yet flexible, polyethylene. They save labor because they are tapered and can easily be removed after the forms have been stripped. OCM Concrete Sleeves may be telescoped or cut to accommodate any slab thickness and are easy to cut with a utility knife.
