Safeguard Multi-Catch Extender measures 30"L x 4 7/8"W x 4 7/8"H. It has two (2) interior spring-loaded doors and a sliding rear door for ease of releasing captured animals.
The Multi-Catch Extender (Large) fits into a Safeguard one-way controller (#53110) as shown, and its purpose is to allow the multiple capture of squirrels and other rodents allowing them to move "away" from the point of entry so the initial spring-loaded door is NOT BLOCKED. You can easily catch 3-5 squirrels in one setting with this Large Extender.
