Frequently Asked Questions

What is the difference between a 10A and 15A extension lead?

A 10A extension lead is suitable for standard household appliances such as lamps, TVs, and phone chargers. A 15A extension lead has a higher current rating and is designed for power tools, air compressors, and trade equipment that draw more power. Using a 10A lead with a high-draw appliance can cause overheating — always match the lead rating to your equipment.

What is a piggyback extension lead?

A piggyback extension lead has a specially designed plug that allows a second plug to be inserted into the back of it at the power point. This effectively doubles the number of devices you can connect to a single outlet without using a powerboard. They are particularly useful in tight spaces behind furniture or appliances.

Can I use an extension cord outdoors?

Yes, but you should use an extension cord rated for outdoor use. We stock weatherproof extension leads with cord covers and outdoor-rated insulation suitable for gardens, patios, and job sites. Standard indoor extension cords should not be used in wet or exposed outdoor environments as this creates a safety hazard.

What length extension cord do I need?

Choose the shortest extension cord that meets your needs — longer cords can cause voltage drop, which may affect the performance of sensitive equipment. For general household use, 3m to 5m leads are common. For trade and outdoor use, 10m to 20m leads provide greater reach. We stock a range of lengths to suit most applications.

Do you sell replacement plug tops?

Yes. We stock replacement 10A and 15A plug tops (Australian standard) for repairing damaged plugs on appliances, power tools, and extension leads. Note that replacing a plug top involves working with electrical wiring — if you are not confident doing this safely, consult a licensed electrician.

Goldair 1200W radiant heater

This is an excellent heater. It’s practical, lightweight, easy to use and gives instant warmth as well as being affordable. The level of heat can be adjusted to one, two or all three bars. I highly recommended it. Fan from Double Bay Hardware was incredibly helpful and accomodating. Wonderful customer service. Cheers, Evelin.

Have only used 1, the other is spare as it is difficult to find these globes & the other one will probably blow any day now as they are connected to the same switch. Works as expected.

I ordered two small light bulbs on line as nobody seemed to stock the ones I needed..
They arrived in a day!
It is so gratifying to find a hardware store that genuinely cares about its customers.
I am also glad to see so many positive reviews.
I live in Crows Nest but I will now make a trip to Double Bay just to check these guys out.
I noticed a review by a customer saying that the prices are too high and to go to Rose Bay Bunnings.
O.K. go to Bunnings and try and get some really knowledgeable advice.
Chances are YOU WON'T!
I would rather deal with genuine people in this world who KNOW what they are talking about and that goes for ALL businesses..
