This 

"Heavy Duty Pan Seal"

will fit the model listed below:

Oster - Sunbeam

Automatic Dough & Breadmaker

Model Numbers: 5811 & 5812 Style BM-100

that was issued with the Heavy Duty Cast Aluminum Pan which has 3 removable screws on the bottom of the pan. 

*If the pan issued with your bread maker is the light weight stamped aluminum pan and does not have any screws 

  on the bottom to take apart the assembly then this seal will not fit.

*FYI: You cannot change the seal in the pan that does not have the 3 removable screws on the bottom of the pan.

THANK YOU!
