Not all Limiting Heights tables are created equally. In fact, as building codes have continued to evolve, the criteria and test procedures that are used to create limiting height data have changed dramatically. These changes have a very significant impact on the limiting height capacity of any specific stud.

For example, ICC Evaluation Service Acceptance Criteria AC86-95 (released in 1995) allowed for a 0.75 load reduction in the formula used to calculate the capacity of a stud. The 2008 version of the same standard, AC86-08, no longer allows the load reduction. Because of this change, the limiting height capacity of a stud varies dramatically depending on the version of the standard used. In some cases these variances can be in the magnitude of several feet!

Additional ProSTUD limiting height charts, meeting AC86-95, are available by call Technical Services.
