Frequently Asked Questions For answers to additional questions please contact bessler@bessler.com or 901-360-1900 Which stair do I select? A.) For truss built structures, a Model 26T or 30T will fit between truss cords. That means they require a 22 1/2" opening. Note that the Model 30 ladder is not as steep as the Model 26. If you need help measuring or are unsure of stairway measurements, please contact us for further assistance. B.) For stick built structures, see Models 20, 26, 40, 70 and 100. The width of the opening is wider on these models. Please note the Model 100 size 1-7 is best used in a commercial application. For residential purposes, the Model 70 sizes 1-7 are more appropriate. C.) Measure your floor to floor not floor to ceiling distance. This measurement is from the floor below to the top of the floor above, which includes the thickness of the ceiling. Use this to determine the stair size from the COMPARISON CHART. Where can I buy Bessler Stairways?
