## Description

Bahco Ergo Big-Mouth Adjustable Wrenches are designed according to Bahco’s Scientific 11-Step Ergonomic Design Program. The wrenches feature extra-wide opening jaws with a shorter handle for maximum access in confined spaces. These wrenches feature up to 45% thinner jaws than standard wrenches of the same size give greater access in tight spaces and a 40% wider opening compared to a standard adjustable wrench. The head combines slim design for accessibility with strength for performance. The jaw does not fall out even at maximum opening of the wrench. The Ergonomically designed thermoplastic elastomer handle distributes pressure uniformly in the hand, reducing the risk for work related injuries. The handle never feels too warm or too cold. Soft, high-friction surface reduces the risk of slipping. This wrench is ideal for plumbers, electricians, and maintenance workers and is perfect for working under the sink, within enclosures, or anywhere that a short handle is needed. Bahco, inventor of the original adjustable wrenches, ergonomics and cutting tools has delivered innovative products for 130 years. In 1886, our iconic Bahco brand was born. Today, it is still a symbol of quality.

## Questions & Answers

**Q: The part number is for the 6" model but under size it says 8". if i order this 9029 R am i going to get the correct wrench? i want the 6" one.**
A: The description has changed since I ordered my last one. The 9029R should only be a 6" as you stated. Amazon should correct this...

**Q: Where is this made?**
A: I have no idea where it is made but I agree about the quality. I give mine quite a hard time. If you prefer the R/H type of shifter/adjustable spanner you have to order the 9029 'R' which has the thumb screw with the right hand thread. I had one a long time ago and someone thought they would do me a favour and clean it with a chemical spray and destroyed the soft handle. I had quite a bit of trouble finding the 9029 R. Everywhere was selling the 9029 which is the left hand screw. I bought one and ended up giving it away because it drove me nuts.Some people prefer the left hand ones. Whichever hand you prefer, order it and you won't be disappointed.Hope this helps

**Q: how wide do the jaw open?**
A: Maximum jaw opening is 1-1/2"

**Q: So what makes these particularly better than other adjustable wrenches?**
A: Short handle with wide mouth, let's you take up the slack in nuts or pipe fittings quick before getting out the big pipe or torque wrench.... Great fit, finish and Laser etched scale are just a bonus. I never go to sea without my fishtailed bahco 😉

*by H***A on 16 November 2018*

Excelente herramienta, las mordazas abren mas que otras llaves de este tipo, ademas la mordaza es mas delgada y puede entrar donde otras llaves no entran por que son mas gruesas. La cola de la llave te permite facilmente usarla como si fuera una llave para tubos.
