Based in South Australia, KEY is known for its commitment to quality manufacturing, rigorous quality standards, and reliable products designed for demanding automotive, electrical, industrial, and resource sector applications. KEY continues to support Australian industry with a strong focus on performance, durability, and dependable engineering.

Superior Conductivity with OFHC Copper Construction

Unlike conventional automotive cables, this 26mm² single core automotive cable utilises high-purity OFHC copper to maximise current flow and minimise resistance. The reduced impurity content helps lower heat generation under load, improving overall system efficiency and reducing energy losses. Whether powering a dual battery setup, feeding a DC-DC charger, or supplying current to a high-capacity inverter, this cable helps maintain stable voltage delivery throughout the system.

OFHC copper also offers enhanced resistance to hydrogen embrittlement and mechanical fatigue. This makes it particularly suitable for installations exposed to constant vibration, temperature fluctuations, and harsh environmental conditions commonly encountered in 4WDs, caravans, commercial vehicles, marine vessels, and industrial equipment.

Designed for High-Current 12V, 24V & 48V Systems

The substantial 26mm² conductor size, commonly referred to as 3B&S automotive cable, is ideal for applications requiring dependable high-current performance over longer cable runs. Rated for a maximum DC voltage of 120V, it is perfectly suited for modern vehicle electrical systems, lithium battery installations, inverter circuits, auxiliary battery banks, and renewable energy systems. The cable's low-resistance construction helps minimise voltage drop, making it an excellent choice for demanding power distribution applications.

Common Applications Include:

  • Dual battery systems in 4WDs, caravans and camper trailers
  • Battery interconnects and auxiliary battery wiring
  • DC-DC charger installations and lithium battery systems
  • High-current inverter and solar power systems
  • Marine electrical systems and battery banks
  • Commercial vehicle, fleet and industrial power distribution

Built to Australian Standards for Long-Term Reliability

Manufactured to comply with AS/NZS 1125 conductor requirements and AS/NZS 3808:2000 insulation standards, this cable delivers dependable performance in demanding environments. The durable V90 insulation provides excellent resistance to heat, abrasion, oils, fuels, and common automotive chemicals while maintaining flexibility for easier installation through chassis rails, conduits, and tight engine bay spaces.

The black outer sheath allows clear identification for negative earth and grounding circuits while maintaining a professional appearance in automotive, marine, and industrial installations. Supplied in a convenient 100-metre roll, it is an economical solution for workshops, auto electricians, fleet maintenance operators, and large-scale wiring projects.

My favorite low socks ever
Fit Type: Classic Fit, Color: Gray Assorted, Size: Large
Under armour adult essential Lite no-show socks are 96% polyester and 4% spandex footwear of imported origin. The polyester content of the socks enables them to hold their shape in a better manner along with having a non-absorbent nature. Additionally, it enables the socks to retain the colour in a better manner. Spandex improves their fit along with helping them last for longer time. The flat fit construction of UA Men's Essential Lite is so designed to conform to foot for superior touch and feel. The material wicks engineered within the fabric dry sweat quickly and keep the feet fresh. The embedded arch support further keeps you going by reducing foot fatigue. The set comes with 6 pairs of socks with pull on closure for the perfect fit. Ultrathin lightweight construction of the socks adds to user comfort by allowing users to conduct physical activity and work out while wearing it. Elastic strength of the socks prevents them from slipping down irrespective of the shoes they are worn with. The socks come in 8-12 men shoe size and 9-12 women shoe size. They can be machine washed and are extremely durable while being cost effective. I ordered the socks based on their colour and design symmetry. So far my socks have been through multiple washes and still look new and user ready. I wear them daily because of their amazing fit and plan to buy more as Christmas gifts.

Love these socks!
Fit Type: Classic Fit, Color: Black, Size: Large
They are a little on the thin side, but that is how I like them. Thin, comfortable, breathable, but still sturdy. They work great for me and I have bought them several times for me and my kids over the years.

Thin
Fit Type: Classic Fit, Color: Gray Assorted, Size: Medium
I bought these thinking they would be slightly thicker material. They are thin but don't make my feet sweat working outside in the heat while wearing them during my work shift. They are comfortable and stay in place so I don't have to keep fishing for them inside my shoe to move them up a bit. The one thing I wish they had was the support band in the middle of the foot.

Super comfortable

Love these socks. They are very soft fabric but also heavy so they are very durable. And the price is far cheaper than any of my local stores.
