Tank - American Standard 4266

Manufacturer: American Standard Tank P/N: 4266 Rough-In: 12" Bolt Spread 7.25”   Tank Only, does not include lid or internal parts. Internal parts and Lid 735128 Can be purchased separately   There are two versions of the 4266 tank, and they are interchangeable with each other. See both photos from above in our photos. It makes no difference which one you have or receive because the lids are designed to work on either and they both mount to the bowl the same way.  We have verified that tank American Standard 4215A can be used in place of the 4266 tank, but the lids are different so you will also need to purchase American Standard 735170 tank lid if you wish to replace your 4266 tank with the 4215A tank.
