The difference between the stamp options is the window sash weight tolerances.

Please remove the window sash and place it on a scale. The weight of the window sash in pounds is needed to determine the proper stamp option.

26B will carry a window sash weight range of 11 through 17 pounds.
26C will carry 17 through 22 pounds.
26D will carry 22 through 26 pounds.

This information is based on 2 balances per sash. Balances are designed assuming friction in the jamb weather-strip will carry a portion of the sash weight. Suggested sash weights are approximate.

If your sash weighs less or more than above contact us again with the weight of the window sash.
