The MC4 assembly tool is a hard plastic material that is very handy for both the assembly of custom MC4 wires, making it easier for new and veteran users to quickly and easily tighten and take apart the connectors.
Be Sure to match with Renogy MC4 Connectors. This Wrench Does Not Fit All MC4 Connectors

These wrenches do not fit all MC4 connectors. I purchased MC4 connectors on Amazon Prime and the these wrenches. The wrenches slipped on the gland nut when trying to assemble and tighten the connectors. They slipped so badly that I could hand tighten tighter than with the wrenches. I was all ready to return the wrenches when I realized that Renogy makes MC4 connectors as well. So I purchased a pack of the Renogy connectors, and the wrenches fit perfectly on them. The Renogy connectors use a gland nut that has lobes similar to torx which provides a great means for engaging the tool to the nut. So the wrench does not slip on the nut at all when tightening. I knocked off a star only because I think there should have been a note in the product description that these wrenches are for Renogy connectors and may not work on other MC4 connectors. I was misled by the product description that MC4 was a standard and this wrench would fit all MC4 connectors. On a side note, the Renogy connectors seem a little bit better quality than the other connectors that I purchased, and the contact material appears to have a better silver coating. Anyway, Hope this helps steer you away from making my mistake. I am pretty new to the many manufacturers of solar products that are available, but my experience with Renogy has been positive so far.
Necessary tool but not compatible with all brands of MC4’s

You really have to have these tools to work with MC4 solar connectors. However, I found out the hard way that they are not all compatible with all MC4 brand connectors (hence 4 stars instead of 5). I don’t know what brand came with my solar panels (they were pre-wired) but this tool did not fit them perfectly. In any event, these tools did the one thing I really needed them to do – disconnect the connects that I had previously connected without thinking – and they did that but with some manipulation.
Worth the money only if you only use them once

I thought these would probabaly be a waste of money but they are not. Another tool you will probably hardley ever use but make things simple when you do use them
Perfect tool for MC4 Assembly
I love it when products perform as expected, are reasonably priced and are well made. That is the case with the Renogy MC4 Assembly Tool. This tool is composed of a lightweight durable hard plastic. There are two included in the package, so for the price, they are a good buy. I purchased this in order to assemble the connectors on our solar system, and it allowed me to do so easily. Just a side note, it fit easily into a woman’s hands, even though when I researched it, most of the reviews had been left by men!

A simple review for a simple tool… it does what it’s made for. Great tool for making and breaking MC4 connections. Made out of rugged plastic, it should last a lifetime.
Didn’t Fit My Specific Connectors
I’m new to MC4 connectors. That said, these did not fit the specific connectors I bought and I don’t know how to know what ones they would. Four stars because they appear to be well made and are solid. I’m sure they would have worked well if they had fit.
