The Knob Kit is designed as replacement hardware for compatible Evolution rollator or mobility equipment models. It helps restore proper tightening, adjustment, or securing function when the original knob is worn, cracked, missing, or no longer holding properly — one small kit covering the adjustment points across seven Evolution model codes.

Ideal for compatible WXR, WXM, WXT, WXW, WXX, WZ, and WR mobility equipment models, rollator repairs, replacement hardware needs, adjustment knob replacement, home care, clinics, long-term care facilities, and users who need a knob kit for approved equipment maintenance. Confirm your equipment's model code against the compatible list before ordering — the kit spans seven Evolution model codes, but the knob must match the thread and position it's replacing, so check the code on your rollator's frame label if you're unsure which model you own. Install the knob per the manufacturer's instructions, threading it by hand first to avoid cross-threading, and tighten it firmly at the adjustment point it secures — handle height knobs in particular are safety-relevant, since a knob that slips lets a handle drop under the user's weight mid-stride, so after installation, set the adjustment to the user's correct position, tighten fully, and test by pressing down on the adjusted component before the equipment returns to use. Recheck knob tightness after the first days of use and periodically after, as vibration from daily rolling gradually loosens hand-tightened hardware, and never substitute a plain bolt for a lost knob, since tool-free adjustment is part of the equipment's design. Replace knobs that are cracked, stripped, or no longer hold tension, and keep spares on hand — adjustment knobs are among the most commonly lost small parts during transport and folding.

Very welcoming and informative. We went in to rent a Walker for my mom to see if she would use it. They had no rentals left so he gave us a brand new one on rental. Highly recommend this company for all your ADL needs.

Fantastic service and experience, from delivery to pickup we could not have asked for anything more! We rented a hospital bed, and I do not believe you would get better service anywhere. Highly recommended!
