This Narva fully insulated battery clamp runs a 500A rating so you can tackle jump-starts and high draw power leads without stressing the gear. The thick gauge pressed metal frame keeps current flowing when a starter is pulling close to 500A on a cold morning. The brass plated steel jaws bite onto posts and lugs with a contact area sized for 500A workshop use. The clamp uses pressed metal and brass plated steel along with a moulded plastic shell to stand up to engine bay heat and road grime common on Australian touring rigs. The red insulation covers the full handle length of about 10–15 cm to separate hands from live metal while you sort batteries on the track. The 500A spec makes it a smart buy for anyone building heavy-duty jumper leads or upgrading existing battery gear.

Q: Is this clamp suitable for making my own jumper leads?

Yes, this clamp is suitable for custom jumper leads built to handle up to 500A. The 500A rating supports high current draw from starter motors and winches. Thick gauge pressed metal keeps voltage drop low over short clamp sections. Brass plated steel jaws give solid contact on posts and lugs. Fully insulated handles help you position the clamp accurately around crowded batteries.

Q: Does the clamp indicate positive or negative polarity?

This clamp is supplied in red, which is commonly used to identify the positive side of a battery setup. Using a red clamp on the positive side helps you keep track of polarity when working around multiple batteries. Matching a black clamp to the negative side keeps your cable set consistent. Clear colour coding reduces confusion when swapping leads between vehicles.

Q: What kind of batteries can this clamp connect to?

The clamp will connect to most automotive-style post and lug battery terminals. The brass plated steel jaws open wide enough for common round posts on passenger vehicles and light trucks. Flat lugs on auxiliary batteries can also be gripped by the jaw faces. The 500A rating suits high draw cranking batteries found in four-wheel drives and work utes.

Q: Is the insulation only on the handle or over the jaws as well?

The clamp is fully insulated around the body, with exposed contact surfaces only at the jaw faces. The insulated shell covers the handles and most of the clamp frame. This reduces accidental bridging against nearby metal when the clamp is in use. Only the inner jaw faces are bare metal to contact the terminal. This layout suits tight engine bays and portable power boxes.
