Model 603SS is a professional live trap with an easy release door for squirrels, muskrats and similar size animals. This trap measures 19L x 6W x 6H. It features a very strong wire frame with tighter mesh patterns and extra reinforcing steel rods welded to the frame for even greater strength. These traps have the same great design as our Original Series traps with stronger materials and more demanding specifications. Tighter mesh patterns not only give the trap additional strength, but also prevent critters from reaching into the trap and stealing bait, and reaching out of the trap and damaging lawns, roofs, decks, and other property. The easy release door allows for the easiest way to release trapped animals and to bait the trap.
