Pierco Foundation for SHALLOW Supers! Measures 4 5/8", foundation sheets snap into frames.
The current batch we have is UNWAXED. These will need to be coated in wax before use. Pierco is still working on getting all of their machinery set up for this new, smaller size so unwaxed is the only option at the moment. ETA for waxed shallow foundation is unknown but it is in the works!
TIP: When installing this into frames, since there isn't as much give in the shorter size, it's helpful to install while you are assembling the frames. Nail your top bar onto the ends, slide in the plastic, and nail on the bottom bar last.
