An apparatus for opening and closing vertically extending, generally straight-line tent zippers without reaching and bending. A first embodiment of the invention includes a first pulley removably mounted on a stake adjacent to and aligned with a lower end of the zipper. A pair of plates each is formed with a plurality of spaced peripheral openings and has a pulley rotatably mounted thereon adjacent to and aligned with another opening formed in the plate. The plates are placed together in a back-to-back relationship so that the plate openings are aligned with each other and with a plurality of corresponding openings formed in the intervening tent wall, for fastening the plates and attached pulleys on the tent adjacent to and aligned with the upper end of the zipper. A cord is attached to the sliding member of the zipper and extends between the pulleys by passing through the other opening of the plates and tent wall and through an opening between the ground and the tent wall adjacent to the lower end of the zipper, so that upon manual pulling of the cord the sliding member slides between the upper and lower ends of the zipper for opening and closing an access opening formed in the tent wall. A second embodiment of the invention is intended for use with tests having an opening formed above the zipper, and replaces the pair of plates and attached pulleys of the first embodiment with a single pulley suspended from the tent frame.
