Product fits: Designed for Mercedes‑Benz E‑Class W212 — specifically E300 and E260 models from 2014, 2015 and 2016. Why you need this: Keeps your tow hitch tube clean and protected from dust, dirt and deposits that can build up in everyday use. Prevents damage or staining to the bumper area around the hitch when the vehicle is parked or driven without a ball mounted. Saves time and hassle by staying attached during car washes and not requiring storage of loose parts. Key features and benefits: Secure attachment: the cover is fixed with a safety strap to the hitch tube so it remains attached while washing or driving. Simple removal and installation: to remove the cover, place the rubber ring onto the hitch tube; no small parts to keep track of. Effective protection: blocks dust and debris from entering the hitch tube and shields the tube and bumper area from grime and deposits. Stable fit: includes a rubber ring/grommet and an elastic strap designed to hold the cover in place on the listed vehicle models. Practical use scenarios: After daily driving: cover the hitch to prevent road dirt and salt from accumulating in the tube when towing hardware is not installed. During automatic car washes: the safety strap keeps the cover attached so it won’t be lost or fall off while the vehicle is cleaned. Long-term storage or seasonal parking: protect the hitch tube from dust and debris while the vehicle is parked for extended periods. Installation notes: Slide the cover over the hitch tube and secure it with the rubber ring; the attached safety strap prevents accidental loss. No extra components or tools required. Compatibility and ordering: Please carefully review the product photos and vehicle fit information before ordering to confirm fit for your E‑Class W212 (E300, E260) 2014–2016.
