Made from engineered composite resins, the E-Z Lok Wheel was designed for use in situations where a lightweight wheel is not sufficient to maintain proper location of the reinforcement. Once attached, this wheel will stay in place.  The unique symmetrical design maintains a consistent cover, regardless of the rebar size. With a wider hub, the E-Z Lok Wheel will not rack or fall off. The E-Z Lok Wheel offers flexibility and strength with multiple hub diameters for rebar sizes from 3/8" (No. 3) to 3/4" (No. 6) and is furnished in a variety of clearances. It is suitable for use with larger diameters of welded wire fabric. The wheel will not change shape and will always provide uniform concrete cover. The E-Z Lok Wheel is perfect for any vertical application where concrete cover must be maintained and is the ultimate side form spacer when strength counts.
