Wooden weasel boards come in two sizes; Medium, which measures approximately 2"W x 16.5"L; and Large which measures approximnately 2.25"W x 21"L. These are made out of 3/16" basswood and will readily accept push pins. If you're going to trap weasels, you need some of these boards.
(Measurements may vary slightly based on the cutting process.)
