Designed specifically for Periboard-835, Periboard-535, and Periboard-335, these Periboard Reinforced Keyboard Feet provide a durable and reliable replacement solution for users who experience broken or unstable original keyboard feet. The reinforced structure is engineered to withstand strong downward typing pressure, significantly reducing the risk of breakage during daily office or professional use. Compared to standard keyboard feet, the upgraded design offers improved strength and long-term durability. This product includes two ergonomic typing angle options (4° and 7°), allowing users to select their preferred typing angle based on comfort and working style. Both angle sets are included in one package, giving flexibility without the need to purchase multiple versions. The modular replacement design installs after removing the original keyboard feet and requires no drilling, glue, or permanent modification to the keyboard housing. Once installed, the feet provide stable support, maintain a consistent typing angle, and help prevent wobbling during use. Manufactured using high-strength 3D-printed materials, these aftermarket replacement feet are designed for daily reliability while maintaining a precise fit for compatible Periboard models.
