 Tri Support Rubber Ferrules For Walking Sticks This is a replacement rubber ferrule with three feet which is compatible with walking sticks and canes featuring a 19mm (3/4") shaft diameter. Its flexible neck allows for the safe use of a walking stick or cane at an angle to the floor and provides a secure grip on slippery or uneven surfaces. As an added bonus, the tri ferrule often allows the walking stick or cane to be stood upright without leaning on anything. |
