An adjustable engagement glide is quickly and removably engaged with tubular products to finish the product end and function as a cap, foot, bumper, or scratch protector on products such as furniture, shop and transportation products, and racks and displays. Engagement is by deformation of a resilient bushing frictionally engaging the tubular product inserted in the glide. The glide is configured for severe service without breakage, has provision to protect surfaces upon which it is supported, but may also be easily disengaged from the product for replacement.
