Know before you buy
The PE foam is designed to dampen unwanted case resonance and refine the acoustic profile of your numpad. It provides a more consistent, muted sound signature by filling the gap between the PCB and the plate.
Choose the 'Regular' option if you want foam coverage under your stabilized 2u keys, such as the Enter, Plus, and 0 keys. Select the '1u' option if you prefer to leave the area under the stabilizers clear.
No, the foam is specifically engineered to accommodate the Freebird Numpad Pro regardless of whether you have the rotary encoder installed or are using a standard switch in that position.
This kit is specifically custom-cut for the stock hotswap PCB provided by Keebsforall. It may not align correctly with third-party or aftermarket PCBs.
The foam is 0.5mm thick. This thickness is optimized to provide effective dampening without interfering with the hotswap sockets or preventing your switches from seating properly into the PCB.
