30"x4.5"x4.5" - A squirrel control dream!  Work flow is never interrupted!  The squirrel pack consists of 1-E40, and 2-M45's.  The squirrel pack is extremely simple to use and highly effective.  Simply locate the entrance hole made by the animal and firmly attach the eliminator, Model E40, to the building, over the hole.  Next, slide Model M45 over the eliminator and hook it into place.  To remove the trapped animal, unhook the M45 from the E40 and replace it with the second M45 that comes with the squirrel pack.
