📦 Hubbell 187 Raco Drawn Extension Ring, 22.5 Cubic Inches, 4x4x1.5", 4-Inch, Product-Specific Review

This extension product from the Conduits & Fittings category of Tools and Home Improvement was a complete waste. After I put it to the test, I noticed that the quality of the product was poor and it didn't work as described. The threads were stripped and it didn't fit into the electrical box properly, causing electrical issues.

It worked as advertised and was easy to install. Nice that the "nuts" were there. From single to double group with lots of ports, regular outlet plus gfci outlet are great.

Needed to connect another outlet to an existing outlet in my garage. I originally used a regular 4" metal junction box, but trying to run multiple sets of wires through a 1/2" KO is tricky. Thought there must be a better way, found these extensions that worked great. Converted my 1 speed box to a 2 speed box with no problems.
