Gerber 99-770 Flapper
Just what I was looking for
By 
My Gerber Avalanche toilet came with a Gerber 99-770 flapper. After about four years of service, the original flapper started leaking. I tried a Corky 3" universal flapper, but that new one leaked also. So, I looked for an original Gerber flapper and none of the big box stores carry them.
The price at Grigg Industries was the lowest even after including shipping, even lower than at Amazon. When I received the flappers (yes, I ordered five!), I was pleasantly surprised to see that these new ones are a bit larger than the original and completely covers the tank opening. These flappers work extremely well. It almost seems like these have magnetic closures.
You cannot go wrong with these flappers from Grigg. Material quality is top notch, design is perfect (easiest to adjust the chain length, easiest to attach to flushing lever) and the price and the delivery time was awesome. Thank you Grigg Industries for making these available to the public at a very reasonable cost.

Excellent product and service

During my search for a replacement Gerber Toilet Flapper, Grigg Industries stood out as having many positive customer reviews stating this product was high quality and worked as it should and that the company was great to work with. Like many of those customers, I had purchased a replacement elsewhere that did not fit right and continued to leak. This flapper looks exactly like the old flapper Gerber 99-770. It fits tight, has good weight, and has not leaked at all. Shipping was fast and I appreciated the prompt and courteous communication from the supplier. I would definitely purchase from Grigg Industries again.
