Q: Is a Special Punch for PESDs with Internal Anti-Rotation Notches Available?
A: Yes, a special punch is available through a partnership with Z-Tech Panel Punches to offer two punches with internal notches that match the below specifications. There is a Single Notch Version (P/N uDL-1210-KEY157-GP) and a 4 Notch Version (P/N uDL-1210-KEY157-GP4) that can be used. If this is a new panel that is being cut, use the diagram below with a laser cutter or water jet to cut out the notches.
However, a properly torqued GracePESDs will be sufficient to prevent the unit from rotating. The hole can be made with a standard 30.5mm punch.
