How many sizes does the classic flap have??? small, medium, large and jumbo????
I think you're right- there's also the east-west which is the long, thin one..
These are the flaps:
and E/W flap
There were also XL Jumbo flaps, but they have been discontinued.
I'll close this since this is at least the 3rd time it's been asked this week.
For reference, the Reference Library has photos, sizes and measurements anytime you want to refer back to it
