Basket Grapple
Basket Grapple is an expandable cylindrical shape insert used inside and overshot bowl for catching and pulling a fish left in a well. It has wickers on inside to catch the fish and tapered helical spiral on the outside that matches with the internal profile on the bowl.
The overshot assembly installed with a basket grapple inside its bowl is lowered to the top of fish. The fish is engaged by swallowing and slacking off. Once engaged, the fish is pulled out of the hole.
