Very well built, great improvement in wire organization and waterproofing.

Easy to install, I like that it comes with plugs for any unused wire spots. Used this to tidy up the wiring in a travel trailer tongue box, it stays dry-ish but if I have to open that box in the rain this will get wet so I wanted to upgrade. I was able to fit a 2ga wire through the power-in slot and it seems to still tighten down snugly around the 4 other 10ga wires coming out to serve power to the trailer. I used Littelfuse Smart Glow fuses that light up if they blow so I should be able to see through the cover if there's a blown fuse without having to open the box and pull each fuse if I need to check. Easy install, screw terminals are quality, two extra screws stored in the cap in case you drop one. Read more

Second one I've purchased. Used one on my custom tractor panel and this is going on my brother's custom panel. Great quality. Seals very well. Easy to install if you are an electrician or mechanically inclined.... Read more
