These are the same ports used in our LessMess and Many Ports feeders.
How to Install Ports
1) Make a mark 2.5 inches from the bottom of the bucket. Drill a small pilot hole at the mark to locate the center of the port. Use a step drill (size 7/8"-1 3/8")
to drill out for the port. Drill the hole just shy of 1.25" to get a snug fit. This will make port installation a lot easier.
2) Insert the port into the hole with the BAFFLE HOOD AT THE TOP and the MOUNTING HOLE AT THE BOTTOM.
3) Driil a 3/16" hole through the mounting hole.
4) Use a 3/16" pop rivet and a backup washer to mount the port.
TO MAKE YOUR FEEDER MORE EFFICIENT
Place a 2qt funnel upside down in the center of the bucket. Plug the stem hole with tape or something else.
This will direct the feed toward the ports.
NOTE: A copy of the above directions with supporting pictures are now sent with orders for ports.
Save money on shipping by ordering enough ports for 5 buckets at one time.
