Weather Resistant Trailer Coupler Caps

Measures roughly 11 cm in length, 8.5 cm in width, and 8 cm in height (4.33 x 3.34 x 3.14 inches), with minor tolerance due to manual measurement. Made from flexible, impact-resistant material suited for outdoor exposure. Contains one trailer plug cap. Designed to cover standard coupler openings found on UK-spec and CE-compliant trailers. Blocks airborne particles and ambient moisture during static periods — preserving smooth operation of the locking jaw and pivot points. Suitable for year-round use, including winter storage and summer festival transport.
