Everything that will make your life easier in the field

My go to tool when I have a major issue. This tool right here is amazing. This one is cheaper then the one I use but it does the same. You can test everything with this in your hand.
Best Wire Stripper
This makes installing so much easier. All the local guys buy them as soon as they see them in action. It’s so much faster when it comes to stripping wire.

Wireless Remote 12/24 Volt 30 Amps
This will make anything 12/24 volts work by remote. They are used to make DS remote systems. Great also for 12/24 soft wash pumps Kill switch if something goes wrong on the roof. You can kill the pump. IE hose springs a leak or line breaks at the trailer spraying everywhere. I have used this for years. The range for them is like 1000 feet.
When running wire & hose through metal, you should also use a rubber grommet to keep the wire and hoses safe. The wire will arch if it rubs the coating off and metal hits the power wire. This is how fires happen.
