Model CB0918SD is our middle sized Comstock Series single door bobcat trap. It features a wire trigger mechanism and fast closing, spring powered internal doors. 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 large and XL Comstock Series Bobcat Trap and the smallest sizes can be nested inside of this trap for easy transportation and storage.
