ABSTRACT:
A device that is used to pull a stake from a newly poured concrete slab. This device allows for attachment to a concrete pole, a tool that is commonly possessed and used by most concrete contractors. It contains a flexible loop that is used for the removal of stakes from the inside of a perimeter of a newly poured concrete slab. The loop of the device is placed so that it encircles the shaft of a concrete stake. A worker rotates the concrete pole until the loop twists enough to tightly hold onto the stake. The stake is then pulled from the ground and lifted up, over, and to the outside of the perimeter of the slab. The invention may include adjustment means to allow its efficient use with stakes of different thickness.
