mk....thanks. If you're asking about how the walleye is attached....there is a 3/8" threaded rod bent at an angle and inserted in the vent area into the body about 8"- 10" or so. The drift. is drilled and rod goes through drift. and base and bolted so it may be removed if wanted. The rod into body is secured w/fast set epoxy...... ;D ;D..fun,eh ???
