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.

PAWISE Pee Pad Holder * Big size *
Size: Small
You GUYS.....they shipped this damn thing in a 65inch TV box Do the measurements and then think about how big a that damn tv box is....literally it arrived and my husband & kids thought 1000% I bought a new TV. So far the product I am happy with / its a bigger square for those dancing pups. I am using this on a Chorkie puppy. The big pads fit and it latches them. Now the pup has realized he can pop the latches but he cant get the pad cause the lid is ontop . Im sure this is a puppy thing and will pass he got redirected and hasnt messed with it since. day 2 of use. *** THANKS JEFF & employees for the huge ass waste of cardboard LOL **

Perfect for puppy!
Size: Small
I got this because I bought another (cheaper) alternative and the pads were shredded within the hour. This holder has the corners of the pad covered and that was the saving grace. Worth the extra money because you aren’t wasting money on puppy pads that are shredded before they are even used. If your puppy is still set on shredding, make sure to add lots of toys on a rotation (never the same toys everyday) and it helps a lot. Once I did that and changed the holder, no shredded puppy pads!

Misleading size stated in adv.
Size: Small, Size: Small
Absolutely ridiculous! Says 23.5” by 23.5 “. It just barely measures a little more than 19 inches. You have to fold up the 24” by 24” per pad to fit it. I don’t know if my 5 pound chihuahua will be able to use it. A complete waste of money!! First photo shows it in frame - 2nd photo show what is a 24 by 24 pad.

FANTASTIC PAD HOLDER
Size: 28'' X 34'', Size: 28'' X 34''
Amazon Basics Dog Training Pad Holder 28X34. I'll start out by saying I wasn't too sure about it, when I got it. It is awkward to put the pads in by yourself if your short as on each end the sides have to come up together and it’s big, however, I've done it five times alone now and it’s doable. There was no smell, it arrived in perfect condition. My husband was home and we set it up together, I walked into the bathroom to get a soiled pad I had keep to put on it for her to know what to do came back and she had already used it and she’s only four months old. I love it love it love it, it’s not too big, but it’s her home too, and we have it in the living room where we spend a lot of time as we’re retired. When she gets a little older, we will probably move it to another room, but for now it’s staying there. After she urinates, it goes down to a very pale yellow color I have been able to use one pad for all day, however, she does have a pad in a under bed tote in our master bathroom. We’ve had a few guests over and if she hadn’t used it they didn’t even know what it was. I highly recommend it. I have been using pads in an under the bed tote for over 10 years and this is a welcome audition. You won’t be sorry if you have little ones that go in the house.

Very easy to use and clean
Size: 22'' X 22''
Saved my pad training with my puppy. It's firm and easy to clean. It holds the pads well for the most part, but sometimes my dog gets a little crazy and it comes out, but I don't think it could be better. Still give a 5-star!
