There are many distributors selling a trap that "looks" like this one, but let us assure you, all traps are not created EQUAL. WCS is manufacturing this trap which includes a number of features not found in any other pigeon trap on the market. Features: 7 Panels, NOT 6 as others have. The 7th panel is used to divide the trap in half when removing birds. Improved Hook & Eye at each panel end for connecting the sections easily. Spring-loaded hooks to hold the top panels and door in place.
