6.25U Spacebar Foam Kit | IN STOCK

This size 6.25U spacebar foam helps fine-tune the typing feel and acoustic profile of your mechanical keyboard. Placed beneath the spacebar, these inserts help reduce unwanted resonance, soften bottom-out impact, and create a more consistent sound profile across the length of the key—particularly important on larger stabilized keys, which can otherwise sound hollow or uneven depending on where they are pressed. Each piece is precision cut from Poron, a high-density polyurethane material known for its uniform compression, excellent vibration dampening, and superior durability. Compared to lower-density materials such as EVA, Poron provides a more refined feel with improved acoustic performance and resilience over time. This part is included with all NULL65 keyboard kits, but is also available here as a replacement or extra.
