URFP Universal Retrofit Foundation Plate
On This Page
Product Details
The URFP universal design provides a method to secure the mudsill to many foundation types. The URFP scalloped, slotted hole feature allows installation flexibility when the mudsill is offset or inset from the foundation edge. With allowable loads deriving from longitudinal embossments and stiffening darts, the URFP may be used as a one-for-one replacement of 1/2" or 5/8" mudsill anchors.
Key Features

Load Tables
These products are available with additional corrosion protection.
- Allowable loads have been increased for wind or earthquake loading with no further increase allowed. Reduce where other loads govern.
- Each anchor bolt requires a standard-cut washer. The Simpson Strong-Tie® Titen HD® heavy-duty screw anchor does not require a washer.
- Nominal embedment depth for post-installed anchors into concrete must be 4" for SET-3G™ or AT-XP®, or use THD50400H Titen HD® screw anchors. Anchorage into CMU is per designer.
- For redwood mudsills, reduce F1 on URFP to 1,180 lb.
- For installation on SPF/HF sill plates, use 0.86 x DF/SP allowable load.
