Abstract
Toilet flappers having an adjustable length cord are disclosed. For example, a toilet flapper may include a frame with a guide structure. A float is connected to a bottom surface of the frame. A cap is connected to a top surface of the frame. A retractable cord reel is housed between the cap and the frame. During installation of the toilet flapper, a user can grab a hook attached to the end of the cord and pull enough of the cord out of the retractable cord reel and through the guide structure so that the user can attach the hook to, for example, a flush lever. In some embodiments, the toilet flapper includes a locking mechanism that impedes the cord from retracting back into retractable cord reel or from being pulled out of retractable cord reel by the user.
