4 x Dust Cap Black Anderson Plug Cover Style Connectors 50AMP Battery Caravan

Leave a 50 amp connector dangling off the drawbar for a week and the contacts collect road dust, salt spray and whatever the last gravel track threw at them. Dirty or damp contacts run warm and drop voltage exactly where a caravan or dual-battery feed can least afford it. These four covers cap the plug whenever it is unplugged.

A rubber ring and a tether do the work

Each cap seats over the connector body and a rubber ring grips it, so the cover stays put over corrugations rather than shaking loose somewhere between the servo and camp. A moulded loop keeps the cap tied to the plug or the cable, which is the difference between a cover you still own in a year and one that went missing the first time you hitched up in the dark. Four in the pack does both ends of a lead with spares left over.

Sized to suit 50 amp Anderson-style connectors

These are aftermarket covers made to fit the 50 amp Anderson-style DC connector — the common two-pole plug used on caravans, camper trailers, boats and dual-battery setups. The 50 amp figure is a size reference for which connector housing the cap sits over, not a current rating of the cap itself; a plastic cover carries no load. Anderson-style housings come in several sizes that look near identical in a photo, so check the size marked on your own plug, or measure it, before ordering.

Key features

• Four in the pack: enough to cap both ends of a lead and keep spares in the drawer.
• Rubber sealing ring: grips the housing so the cap does not vibrate off on corrugations.
• Retaining loop: stays tethered to the plug or cable, so it cannot be dropped and lost.
• Keeps contacts clean: dust, grit and moisture stay off the terminals while the plug sits idle.
• Handy where a battery comes out often: the plug gets capped between uses instead of sitting open.
