Practical Limits
The cap is a direct press-on replacement that snaps onto the existing wiper arm end without tools or fasteners. It does not alter wiper mechanics, blade contact or motor function. Buyers needing a complete wiper arm assembly or a different colour will not be served by this single black cap.
Build And Daily Use
Made from durable plastic with good hardness, the cap resists cracking and breaking under normal exposure. Its 71 by 27 by 25 millimetre profile sits flush once installed, shielding the retaining nut from scratches, corrosion and weather while adding a clean black finish. The single-piece pack covers one rear wiper only.
