Know before you buy
The foam is available in both ANSI and Arrow layouts to match your specific Freebird 60 configuration. Please ensure you select the version that corresponds to your PCB layout before ordering.
This product is specifically engineered for the stock hotswap PCB provided by Keebsforall. It may not align correctly with aftermarket or custom PCBs.
The 0.5mm thickness is designed to provide a subtle dampening effect without significantly altering the bottom-out feel of your switches. It primarily serves to refine the acoustic signature of your build.
Cross-linked PE material is favored in keyboard modifications for its consistent density and durability. It effectively helps to create a 'poppy' or 'thocky' sound profile by isolating switch vibrations from the PCB.
No adhesive is required. The foam is precision-cut to sit securely between your switches and the PCB, making it a non-permanent modification that is easy to install or remove.
