The URFP universal retrofit foundation plate is the new, improved version of the UFP, offering increased load while maintaining the same adjustability during installation. Ideal where there is minimum vertical clearance, the URFP provides a retrofit method to secure the mudsill to the foundation. This new design allows installation flexibility when the mudsill is offset or inset from the foundation edge. With its combination of longitudinal embossments, stiffening darts and scalloped slotted holes, the URFP allows for a one-for-one replacement of 1/2" or 5/8" mudsill anchors as well as fixity to both the SDS screws and required concrete anchorage.
The next generation FRFP flat retrofit foundation plate connects the mudsill to the foundation and provides lateral load resistance. This new design allows the Designer to maintain the same prescriptive requirements when filling the original three holes, or as an alternate, fill the newly added two optional triangle holes and utilize increased loads and greater allowable spacing.
URFP — 14 gauge; FRFP — 7 gauge
Galvanized. May be ordered HDG; contact Simpson Strong-Tie. See Corrosion Information.
Use all specified fasteners; see General Notes.
Loads are based on test results using Simpson Strong-Tie® Strong-Drive® 1/4" x 3" SDS Heavy-Duty Connector screws, which are supplied with the URFP.
For URFP, alternate lag screws will not achieve published loads.
FRFP shall use a minimum Strong-Drive SDS Heavy-Duty Connector screw length of 2 1/2" plus the shim thickness. FRFP may be installed with 1/4" HDG lag screws. Follow code requirements for predrilling.
