  • Concrete products locking cage spacer
    Patent number: 9745752
    Abstract: A spacer for spacing the reinforcing cage from the forms used in making concrete products. The spacer of the invention is made from plastic in the shape of a wheel with spokes that join an outer ring with an inner ring that engages a horizontal wire on the wire cage. The rings have gaps to provide for installation of the spacer on a cage wire. The gap in the outer ring is closed by a latch that when properly engaged, will lock the spacer in place on the wire, thus positively holding the spacer on the wire once it is locked in place.
