[Good protection] Our elastic end caps help prevent wear on kitchen or wooden floors, ideal for metal chair tips, furniture, chair legs, table legs, screw threads, nail heads, or covering any round tube. [Flexible material] The protective cover is made of high-quality PVC for flexible heat insulation. [Size selection] Since the material is soft and elastic, we recommend choosing a rubber end cap slightly smaller than the outer diameter of the item being protected. For example: if the outer diameter of your item is 9.8 mm, choose a 9.5 mm rubber sleeve. [Wide application] Suitable for covering screws, threaded parts, round pipes, furniture feet, and more.
