For those interested in converting a folding walker into a wheeled walker, these 5-inch Walker Wheels from BEK Medical will make the transition possible. They are compatible with most manufacturers’ walkers and will provide you with the ability to choose from 11 different height adjustments. The wheels are made out of rubber, which makes it easy for them to glide over most surfaces. This kid comes packaged with rear glide caps (item No. 10107) and glide covers (item No. 10107C) designed to work on those same surfaces. These wheels have a weight capacity of 350 pounds.
