Review: Fixed toliet - Fit perfectly. I used this in my toilet because I had to jiggle the handle to stop the water from flowing into the bowl. Looked online for symptoms of toilet running and this is one of the thing to replace. So it was a very easy dyi and problem solved. Inexpensive fix. Review: As easy as it gets. - Super easy installation and fit. This single handedly fixed a leaky toilet that was costing me tons of money on each bill. Definitely worth the price. ## Features - Made in United States ## Technical Specifications | Specification | Value | |---------------|-------| | Asin | B00E5ICW0E | | Best Sellers Rank | #154 in Tools & Home Improvement (See Top 100 in Tools & Home Improvement) #1 in Toilet Flappers | | Color | Red | | Customer Reviews | 4.5 4.5 out of 5 stars (15,600) 4.5 out of 5 stars | | Date First Available | July 23, 2008 | | Finish | Red | | Included Components | Chain(1) Toilet Flapper, Flapper | | Item Model Number | 100BP | | Item Package Quantity | 1 | | Item Weight | 1.4 ounces | | Manufacturer | Korky | | Material | Rubber | | Number Of Pieces | 1 | | Part Number | 100BP | | Pattern | Flapper | | Product Dimensions | 4 x 7 x 2 inches | | Shape | 2 Inch | | Size | Small | | Style | 1 PACK | | Warranty Description | 5 Year Warranty | ## Images ![Korky Standard 2-Inch Ultra High Performance Universal Toilet Flapper - Image 1](https://m.media-amazon.com/images/I/61I4DhDugWL.jpg) ## Available Options This product comes in different **Number Of Items** options. ## Questions & Answers **Q: The dial on the flapper: How does it work?** A: Great question! There are several numbers located on the underside of the flapper near the band. By turning the dial to the higher numbers, it closes off the holes allowing the flapper to float longer (this cause more water to enter your toilet bowl. By turning the band to the lower numbers, the flapper takes on water and closes faster (flushing less water).
