ACCP Single Red Head Jack Cover
The single red cover for a Lumedyne Head jack is ready to cover one Head jack when not in use. It is one of the same ones that were included with the Classic Power Packs. It has no holes in it, so it is best sealed but it is not water proof.
This is the individual little red round cover that most people eventually lost that came standard on the Classic Packs or the ones attached with a leash to the front of the modern Packs.
This is a single version of the same red covers originally provided with Classic Packs individually and now already attached to the front of the modern Packs. This is a single replacement for a lost cover.
A different product is two covers with a short leash between them is called the ACCX.
These DO NOT help make the Lumedynes water proof! They do help avoid splashes reaching your high voltage connectors. Don't get Lumedyne gear wet. However, these should help keep your important connectors as clean as possible whenever they are not in use.
