Model CB0918SD is our small sized Comstock Series single door bobcat trap at 38 x 9 x 18". 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 medium or large Comstock Series Bobcat Traps for saving storage and transportation space. All Comstock Series Traps are made to order and manufactured on a first in first out basis. Please allow additional processing time for this item to ship.
