A crab trap float has a hollow cylindrical center rope-receiving tube. A rope stop has a round cap and a tubular throat which fits down inside the float center tube. Circular ridge lips on the tubular throat hold it in the float. Rope grippers extend inward at the bottom of the tubular throat to tightly grip the rope as the tubular throat is pushed into the float. The inside of the smooth bore of the throat is grooved in a 4-leaf clover design for forming a gripper to hold the rope and to prevent the float from traveling along the rope. The rope is tied to the trap and is passed upward through the inside the float and through the tubular throat and its cap. Straightening the rope positions the float over the trap. A knot is tied on top of the cap. The top is jerked and the tubular throat of the gripper is forced down into the float, locking the rope in the gripper and the gripper in the float.
A crab trap float rope stop assembly, comprising a spherical crab trap float formed around a central abrasion-resistant float tube, a crab trap rope extending through the abrasion-resistant tube, a stop surrounding the rope, the stop having an enlarged upper end for abutting an upper end of the float tube and for preventing movement of the stop through the float tube, a depending tubular throat connected to and extending downward from the enlarged end, the tubular throat having plural external, generally radially extending anchors for permitting movement of the tubular throat and anchors into an upper end of the float tube and for preventing outward movement of the stop, the throat and the anchors extending from the throat into contact with the float tube for anchoring the throat, anchors and stop in the float, a plurality of rope-gripping extensions extending inward from the throat for jamming inward against a rope as the throat and anchors are deformed radially inward upon being compressed in the float tube for preventing movement of the rope through the stop.
A crab cage float rope stop apparatus, comprising a stop for surrounding and engaging a crab cage rope, the stop having an enlarged upper end for abutting an upper end of a float tube in a crab cage float and for preventing movement of the stop through the float tube, a depending tubular throat connected to and extending downward from the enlarged end, the tubular throat having plural external, generally radially extending anchors for permitting movement of the tubular throat and anchors into an upper end of the float tube and for preventing outward movement of the stop, the throat and the anchors from the float tube for anchoring the throat, anchors and stop in the float, a plurality of rope-gripping extensions extending inward from the throat for jamming inward against a crab cage attached rope as the throat and anchors are moved radially inward upon being compressed in the tube for preventing movement of the rope through the stop.
A method of installing a crab cage and float, comprising tying a knot in a first end of the rope, passing the rope through a smooth opening in a stop with a cap and a throat and through separated inward extending grippers in the throat, passing the rope through a tube extending through a float, jerking sharply on the rope and pulling the throat into the tube, compressing anchors extending from the throat in the tube and anchoring the anchors and throat in the tube, gripping the rope by compressing the grippers against the rope, pulling the cap up against an end of the tube, and tying the second end of the rope to a crab cage.
