Bag Adaptor Ring for Six In. Twist Lock Hatch

The Six Inch Adaptor Ring for the Viking Six Inch Twist Lock Hatch will allow you use a Viking brand Six Inch Cat Bag or a generic six inch hatch bag. Originally for use with the Viking brand PTL six inch hatch, this might be used as a bag rim and backing plate for a Valley style 8 inch hatch rim. Nine Inches OD, 5.5 inches ID, screw holes are 8.25 inches on center.

Custom mounting may be necessary. Hatch and ring must be mounted at same time. You will dismount the existing old hatch rim and re-mount with this ring under it. Gain insight with these links:
