This trip lever tub drain trim kit can upgrade your bathing experience—it not only enhances the appearance and functionality of your existing trip lever-style tub drain but also comes with step-by-step DIY installation instructions to help you better complete installation and fixing. Its matte black finish can match your tub faucet and the rest of your bathroom décor, and no putty is required for installation. The kit is made of high-quality materials: the main body is constructed from brass, zinc alloy, and ABS, ensuring long-lasting durability. The coating technology has been upgraded to improve anti-flaking performance, allowing it to maintain good condition even when soaked in water for a long time without easy damage. It features a standard design that fits most tubs and baths. The threaded bushing is compatible with 1-1/2 inch and 1-3/8 inch bath shoe sizes, and the drain can also fit both 1-1/2" coarse thread and 1-5/8" fine thread drain shoe sizes. When you screw the brass adapter bushing onto the tub drain, the diameter is 1-13/16", which fits 1-1/2" coarse thread; when you unscrew the brass adapter bushing from the tub drain, the diameter is 1-5/8", which fits 1-5/8" fine thread.
