The blue 7U spacebar in the R2 Preserving Kit is intended for R1 buyers who own the Value, Clarity and West Kits allowing them to fit two boards with this new R2 Preserving Kit. Additionally, it serves as a 7U spare spacebar for R2 buyers. I also included a 1.5U Accent Control key for a new refreshing touch, which is also a nice addition for R1 buyers. Thank you for your support!
