Model CB1021SD is our second largest sized Comstock Series single door bobcat trap. It features a wire trigger mechanism and fast closing, spring powered internal door. Unlike other bobcat traps with external guillotine doors that extend well above the frame, these traps have “zero” clearance because nothing extends beyond the confines of the trap body itself upward or outward. This trap is also excellent for fox and similar sized animals. This trap can be nested inside the largest Comstock Series Bobcat Trap and the smaller sizes can be nested inside of this trap for easy transportation and storage.
