Factory replacement belt for the TK4 and the TT132 that measures 3/16″ wide and 4 5/16″ long when flattened out and is cogged.
Here is a hint:
Buy two and store the second belt in the bottom of your vacuum for future needs! When the belt breaks once again you will never need to search for a new belt or wait for a replacement to be shipped to you.
SAVES ON SHIPPING COST TOO!
