The Bridger #2 Dogless Trap is a very useful and popular trap for many trappers targeting medium size critters.  The dogless design is a fairly new option offered by Bridger, and the trap comes stock with a rectangle shaped pan measuring 8.244 square inches.  The Expand-A-Pan bolt on replacement pan increases the surface area to 161% of the original pan size, or 13.242 square inches, a real help to eliminate those trap pattern misses.  Expand-A-Pan……Go Big Or Go Home!
