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