What is the difference between a “Special” and a “Custom” connector? A “Special” is a stock USP connector that is modified within the limits listed in the Specialty Options chart for that connector. A summary of Specialty Options can be found on page 245 of this catalog.
*Actual steel dimensions will vary from nominal dimensions according to industry tolerances.
Maximum Shear Capacity of Joist or Rafter The table below indicates the calculated shear capacity of different dimensional lumber sizes for various wood species.

A “Custom” is a connector that does not closely resemble a stock or special part offered in our catalog. Also, a “Custom” connector may be a stock connector that is modified outside of the limits listed in the Specialty Options charts or is not listed in the catalog as having a specialty option available. Product drawings must be provided by the customer and will be manufactured by USP in accordance to customer specifications.
