Description

STOP PARASITIC BATTERY DRAIN - Knife-blade disconnect lets you cut power to the negative battery post in seconds so stored vehicles, RVs, and seasonal equipment hold their charge between uses.

HEAVY-DUTY 12V RATING - Rated 250 Amps continuous and 750 Amps surge at 12 Volts, giving the headroom needed for cars, trucks, RVs, boats, and other 12V systems running standard accessory loads.

FITS STANDARD TOP POST BATTERIES - Clamps onto a 5/8 in diameter negative top post for a secure cable-clamp connection, with low vertical lever operation for easy reach inside the battery box.

EXTRA STUD AND WING NUT CONNECTIONS - Integrated 5/16-18 threaded stud with wing nut accepts ring-terminal leads, so auxiliary accessories, chargers, or parallel battery cables can land on the same disconnect.

SECURE AND COMPACT DESIGN - Compact 3 in W x 4 in L x 2-1/4 in H footprint helps deter theft, tampering, and unauthorized use by removing power at the source; made in the USA.

Common questions about buying open-box and refurbished.

Why buy refurbished or open-box?

Refurbished and open-box products offer the same performance as new at a fraction of the price. You're already saving $12 on this listing. They've been inspected, tested, and are ready to use — the only difference is the price tag. Buying refurbished also reduces electronic waste, extending product life cycles and keeping functional devices out of landfills.

What's the difference between open-box and refurbished?

Open-box products are customer returns that have been inspected and confirmed functional. They may show little to no use — often the item was returned simply because the buyer changed their mind. Refurbished products have been professionally repaired or restored by technicians, tested to meet or exceed manufacturer specifications, and sometimes come with a warranty. Both are a smart alternative to buying new.

Why use OpenBoxFox?

Finding refurbished deals is time-consuming — you'd have to check Amazon Warehouse, Reebelo, Dyson Outlet, and others separately for WirthCo products. OpenBoxFox aggregates these listings in one place, so you can compare and find the best deal without the legwork. We update pricing daily so you always see current availability and real savings.

Is it safe to buy refurbished?

Yes. Products listed on OpenBoxFox come from established retailers like Amazon, Reebelo, and Dyson — not unknown third-party sellers. Each retailer has buyer protection policies, return windows, and in some cases warranties. You get the price advantage of used goods with the purchase security of a known retailer.
