Mueller-Kueps MLK745100 Wrench (Extender)

Works great for wrenches up to 15/16 or 24mm. Not for smaller wrenches. They have different sizes of these type of wrench extenders.

Well, it's a tool that can be quite helpful and handy when needed.......but that's not often at least for me. It works well, is easy to use and is very strong. It will last beyond my lifetime I'm sure. It adds alot of leverage, more than I expected. It seems a little pricey for a toll i might use twice a year but it's sure nice when you need it. Much better than trying to rig up some other form of leverage on a wrench. I'd buy it again because I like gadget tools that actually serve a useful purpose even if they aren't needed much.

You will love this tool. If you've ever had to buy different size pipes or cheater bars for different wrenches, or you can't use the double wrench trick on a brake line ... you know the struggle. This thing fits all of my daily use wrenches as a mechanic and is easy to store in shallow wrench drawer. Torque multiplier is insane for the length of the tool. Super impressed. It is heavier than it looks, but I prefer strong tools that will last forever.

Great addition to any tool box. No more busted knuckles. Only thing was the square 1/2" hole for the breaker bar was too small and I had to file it out.

When you need to extend your wrench to gain better leverage, the old trick of using another wrench as a cheater bar is an injury waiting to happen. This wrench extender will eliminate the chances of slipping off your wrench and sending your knuckles straigh into obstructions. The design also allows you to use either end of your wrench, as opposed to only the boxed end on the two-wrench technique. It also features a 1/2" drive cutout on the end of the tool to attach a ratchet or small breaker bar to gain even more leverage. Having said that, I have two issues with this tool. The slots that hold the wrench are too close together, which limits the possibilities of wrenches that can be used. Some wrenches are wider than others and I have tried some wrenches that this extender will not accept. The finish is also very poor, which considering the price of the tool is a disappointment. If you can live with the shortcomings, this tool is a great addition to your toolbox.

I borrowed this tool from the mechanic who works next to me to break loose some stubborn control arm nuts that were seized I normally use a pipe but went missing .this tool latches on to the wrench nicely and is comfortable to use broke loose the nut with out having the need to heat it up with a torch . I ordered it the very same day received it a couple days later and has saved my knuckles multiple times great product very happy with my purchase.

Wish I would have bought this sooner, useful for getting extra leverage, especially if you need to Put a ratchet on the end. Most likely you will exceed the grip of the wrench on the bolt instead of not having enough torque (especially on the open end) but great nonetheless, so if you already have high quality wrenches, this is a great addition. It is also stronger than it appears in the picture, I didn’t realize the thickness from the photo.

This is a quality product, very sturdy. I have in the past used a second wrench or a pipe for extra leverage. This works much better! It is by far more solid and gives you more confidence to bear down on the wrench. No more looking for a pipe with the proper diameter to fit the wrench saves time.

This is a very solid piece of hardware. How solid is it? Well you know those tiktoks where they demonstrate extracts by snapping bolts? I'm able to very easily replicate them now with my box wrench set! With all due seriousness though, this is great. When used properly it really does give you just that bit extra oomph for your solid wrenches. I generally use this tool to break things loose and for getting some extra torque out of solid wrenches in very tight spaces. I would be rather terrified of using this in tightening scenarios as, if used without discretion, will absolutely allow you to destroy bolts. So take caution. But this does also support how well built and great of a tool it is. One bit of annoyance is that in order for you to lock your wrench into the handle for either a clockwise or counterclockwise turn, it will require a bit of brain work. The way the wrench interlocks into this handle isnt the most intuitive and requires a bit of focus. You cant really brainlessly wrench on stuff. This isnt a dig, it just means you have to be intentional when setting this tool up with your wrenches. I personally find that great because it gives me a chance to back out of potentially putting 200 ft lbs of ape torque into an 8mm bolt. Regardless, great tool, get it if you need it. Its well built.

I’m super happy with this product. I used to use 2 spanners to crack a bolt and end up with a broken spanner.It not only use for spanner but also work well with ratchet and other mechanic tools.Good pricing!

quality is good just too heavy.

Thick, sturdy and the curvature makes it perfect for all types of spanners. And it's lots more safer than doubling up on spanners

But know that it's not going to fit on wrenches bigger then about 1 1/6.Not a design flaw. Just need to be a bigger size yet for bigger wrenches.
