The first pulley mount comprises a first portion and a second portion that are removably coupled to each other with a portion of the curtain between them when mounted to the curtain. A second pulley in included along with a second pulley mount constructed and arranged to couple the second pulley in position relative to the curtain. An elongated pull is coupled to the first pulley, the second pulley, and a zipper pull of the zipper. ## Claims ### Claim 1 A method of installing a pull coupler into a zipper pull system, comprising the steps of: providing an elongated pull comprising a first end and a second end; providing a pull coupler, comprising: a first portion, comprising: a first portion channel, a rear opening, and a front opening, wherein the first portion channel constructed and arranged to engage with an elongated pull; and a second portion coupled to the first portion, the second portion comprising a rear opening, the second portion constructed and arranged to couple with a zipper pull; inserting the first end of the elongated pull into the rear opening of the second portion; knotting the first end of the elongated pull inside the second portion, the knot being wider than the rear opening of the second portion, the knot being constructed and arranged to prevent the first end of the elongated pull from leaving the pull coupler; and inserting the second end of the elongated pull into the rear opening of the first portion and through the first portion channel. ### Claim 2 (depends on 1) The method of claim 1, wherein the first portion of the pull coupler further comprises a first extension. ### Claim 3 (depends on 2) The method of claim 2, wherein the first extension comprises at least one opening. ### Claim 4 (depends on 1) The method of claim 1, wherein the pull coupler further comprises a second extension. ### Claim 5 (depends on 4) The method of claim 4, wherein the second extension comprises at least one opening. ### Claim 6 (depends on 4) The method of claim 4, wherein the first extension and/or the second extension comprise one or more teeth. ### Claim 7 (depends on 6) The method of claim 6, wherein the one or more teeth are constructed and arranged such that the one or more teeth of the first extension face the one or more teeth of the second extension. ### Claim 8 (depends on 4) The method of claim 4, wherein the first and second extensions are constructed and arranged such that the first portion channel passes between the one or more teeth of the first extension and the one or more teeth of the second extension. ### Claim 9 (depends on 4) The method of claim 4, further comprising the step of passing the second end of the elongated pull through the first portion channel of the first portion. ### Claim 10 (depends on 9) The method of claim 9, wherein the first portion channel is constructed and arranged such that a resistance to the elongated pull passing through the first portion channel is greater in one direction than an opposite direction. ### Claim 11 (depends on 10) The method of claim 10, wherein the first portion channel is constructed and arranged such that the elongated pull can pass through the first portion channel from the rear end of the first portion towards the front end of the first portion with less resistance than the elongated pull passing through the first portion channel from the front end of the first portion towards the rear end of the first portion. ### Claim 12 (depends on 1) The method of claim 1, further comprising the step of inserting the second end of the elongated pull through the front opening of the first portion. ### Claim 13 (depends on 1) The method of claim 1, wherein the front opening of the first portion is constructed and arranged to be aligned with the rear opening of the first portion. ### Claim 14 A method of assembling a zipper pull system, comprising the steps of: providing a first pulley mount comprising a first pulley; providing a curtain comprising a zipper, the zipper comprising a top region and a bottom region; coupling the first pulley mount to the curtain at a position above the top region of the zipper; providing a second pulley mount comprising a second pulley at a bottom region of the zipper opposite the top region of the zipper, mounting a pole relative to the zipper so that a lower end of the pole is coupled to a portion of the second pulley mount; coupling an elongated pull to the first pulley and second pulley so that a first portion of the elongated pull is at a first surface of the curtain and so that a second portion of the elongated pull is at a second surface; and coupling the elongated pull to a zipper pull of the zipper at a pull coupler that mechanically clamps the elongated pull in position at the zipper pull. ### Claim 15 (depends on 14) The method of claim 14, wherein the first pulley is positioned at an interior region of the first pulley mount. ### Claim 16 (depends on 14) The method of claim 14, wherein the first pulley mount comprises a first portion of the first pulley mount and a second portion of the first pulley mount, wherein the first portion of the first pulley mount and the second portion of the first pulley mount are slidably coupled to each other with a portion of the curtain between them when mounted to the curtain. ### Claim 17 (depends on 14) The method of claim 14, further comprising coupling a pull coupler to removably secure the elongated pull to the zipper pull.
