Variety of Waterproof Junction Box:

Waterproof junction boxes are used in a variety of industrial, commercial, and residential applications. They are used for carrying electric cables, wires, pipes, etc., among other items. 

There are a variety of different types of waterproof junction boxes that are available in the market today. Some of the most popular and widely used types of waterproof boxes are discussed below.

  • Stainless Steel Waterproof Junction Box:

Most of the waterproof junction boxes are made of stainless steel. This means that the wires that you feed through will be able to handle a lot more abuse than they could if they were made from other materials. 

The problem is that they are also the most expensive of all the waterproof junction boxes out there. If you are going to be using this type of box outside, then you definitely want to invest in the best ones that you can find because you can be sure that they will last you for a very long time.

  • Plastic Waterproof Junction Box:

A good example of the material that these waterproof junction boxes are made out of is plastic. The good thing about plastic is that it is extremely durable and doesn’t rust as some other metals do. 

Another advantage to plastic is that it is very lightweight, which makes it easier for people to carry them around. One of the downsides to plastic is that it does not insulate very well, and that means that you will usually need a box cover on top of it in order to keep the heat in during the winter. You can expect these plastic waterproof junction boxes to last for a few years, but you might have to replace them sooner rather than later.

  • Aluminium Waterproof Junction Box: 

The next option on the market is aluminium waterproof junction boxes. These are usually going to be heavier than the plastic ones, but they will last far longer and are much better at insulating. The downside is that they are more expensive than the plastic grade. 

If you are going to be spending a good amount of money on an aluminum waterproof junction box, then it is probably a good idea to buy the highest quality that you can afford.
