Shark Teeth come in 36" strips that are 1 1/2" wide. There are three to a set, and the set includes three self tapping screws per strip (9 total). Each strip has 4 parting lines 6" apart. Each 6" strip has 4 pre-punched holes. You can apply complete 36" strips to feeder legs. Then buy our single pack or triple pack and cover your Protein/Gravity Feeders head (or) Control/Timer Box, to create a barrier that repels just about anything.
