phone 330-939-3673. they have what they call a animal catcher in two sizes, 34" and 48". yes you can make your own by fastening a piec of cable to the end of a metal pipe, run the cable back thru the pipe makeing a big loop in the cable where it is fastened to the pipe (loop should be big enough to slide ofer the head of the biggest animal you want to handle), allow about 12" of cable on the oposite end, drill a hole thru a piece of broom stick and fasten loose end of cable ot it. this will work but almsot reauires an extra hand to release the trap as both your hands or busy useing the release pole. the manufactured ones i have have some kind of pinch stop that holds the cable at the point where you stopped tightening it and then by pulling on the end you can release it.
