Replacement protective chute cover for very early Super Feeder models CSF-3, CSF3XL, KSF-2, KSF-2XL. If the actual chute opening "height" of your feeder is less than 1" high (actually 3/4") you have the early model. Late model feeders, always come with a larger chute cover installed. If you unfortunately have a "locksmith" type cat, this cover will help reduce the chance of getting food out. It will not protect against large animals and wild animals like Raccoons where it could be ripped off! WE RECOMMEND THAT YOU TEST and use the SMALLEST suitable cat food when using this cover to assure best performance and dependability. Typical small 1/4" to 3/8"diameter spherical/square/barrel shape kibbles like offered by Science Diet, Blue Buffalo's, Wellness Kibble should work just fine! Some customers may not really need a chute cover on an early model feeder, but if you have a real mischievous cat, this is the answer to a potential chute intrusion problem common with many other feeders. If ordered by itself you will need to follow the instructions below to install it: WHILE HOLDING FEEDER UPSIDE-DOWN, REMOVE BOTTOM OF FEEDER BY UNSCREWING THE 6 SMALL STAINLESS STEEL SCREWS, MOVE SHAKER WIRE OUT OF WAY, MOVE DISTRIBUTION SLIDE OUT OF THE WAY, THEN SLIDE CHUTE COVER STRAIGHT INTO THE CHUTE OPENING. RE-INSTALL IN REVERSE ORDER BY MAKING SURE SHAKER WIRE IS AGAINST BOTTOM OF SLIDE. THE CHUTE COVER DOES NOT SNAP IN OR OUT, SO DO NOT TRY TO PULL IT OUT OR FORCE IT IN WITHOUT REMOVING FEEDER BOTTOM OR YOU WILL BREAK IT!! INSTRUCTIONS WILL BE INCLUDED WITH THE CHUTE COVER ORDER.
