This is a direct replacement lid for 40oz Stanley The Quencher Tumbler. My wife's tumbler was knocked off the bleachers at a baseball game the other day breaking the lid. Instead of buying the $10 replacement, she ask if I could give it a try. The replacement works perfectly, threading match up and there is a lip for the rubber o-ring to fit into to make it waterproof.
I reused the center piece from the existing lid as it wasn't damaged in the accident. V2.0 will include a replacement center piece with a TPU insert.
