Evolution Replacement Knob Kit for Trillium and Xpresso Series (Xpresso Zero, Xpresso Wide, Xpresso Lite, Xpresso Standard)

Evolution® Replacement Knob Kit — Trillium & Xpresso Series

The Evolution® Replacement Knob Kit provides replacement adjustment knobs for compatible Trillium and Xpresso series rollators. The knobs help secure adjustable walker components, including handle-height adjustment points, and restore proper tightening and positioning when original knobs are worn, cracked or missing.

Important Compatibility Note: Evolution uses different knob-kit references for different walker families and generations. Current Evolution documentation lists separate Trillium and Xpresso Zero knob-kit selections, while Canadian parts listings identify B12IR for Trillium and B12XP for Xpresso. Select the correct type for the exact walker before ordering.

Usage and Safety Information

Confirm the exact Evolution walker model and generation before installation. Do not substitute a knob with a different thread, diameter or length unless the manufacturer specifies it as compatible.

Install the replacement knobs in the original adjustment locations and tighten them securely according to the manufacturer's instructions. Do not overtighten or use tools unless specifically directed by Evolution.

After installation, verify that the adjustable component remains firmly positioned and does not move unexpectedly. Re-check the knobs periodically for looseness, especially after repeated folding or transport.

Do not use the rollator if an adjustable handle or frame component cannot be securely locked into position, or if the knob is cracked, stripped or damaged.

Important: Do not treat all Evolution knob kits as interchangeable. B12IR is the common Trillium reference and B12XP is the common Xpresso reference, while specific Xpresso generations such as Xpresso Zero may have their own selectable configuration. Match the kit to the exact walker.
