Review: Solid, Reliable Basin Wrench That Gets the Job Done - This Duratech basin wrench is a solid, well-built tool that performs exactly the way a standard basin wrench should. The construction feels strong and durable, with a good weight to it, and the jaw locks onto nuts securely without slipping. The motion is smooth, and it gives you the leverage you need for tight spots under sinks where normal wrenches or channel locks just won’t fit. It doesn’t extend, but that’s not a downside for me—this is a standard-size basin wrench designed for everyday plumbing work, and it works perfectly in that role. If you specifically need the extra reach, you’d simply buy an extendable version. For what this one is meant to do, it does it extremely well. The handle is sturdy, the swivel head grabs onto hardware firmly, and it feels like a tool that’ll last through plenty of jobs. If you’re replacing faucets, tightening or loosening supply line nuts, or working in those cramped spaces behind a sink, this wrench makes the job a lot easier. Overall, a reliable, no-nonsense basin wrench from Duratech. Strong build, great grip, and does exactly what it’s supposed to do without any issues.
Review: Perfect fit - Iitem is a must have tool. Works great.

## Questions & Answers

**Q: Can I use this on sprinkler shut off valve underground?**
A: The answer is a guarded yes and no.  That really depends on how deep the sprinkler shutoff valve is and whether or not the part that you seek to turn is within the range of the wrench that is 3/8" tp 1-1/4". Buried sprinkler shutoff valves tend to be difficult to impossible to turn due to corrosion.  To save money, contractors will sometime install lesser expensive valves that are inappropriate for underground applications.  Consider shutting off the main water supply valve before attempting to turn an underground sprinkler shutoff valve least you end up with an expensive flood.

**Q: What are the head's dimensions?**
A: Dear Customer,
Telescoping basin wrench fits any lug nuts and fittings measuring 3/8 inch to 1-1/4 inch in diameter.
Best Wishes,
DURATECH

### ⭐⭐⭐⭐⭐ Perfect fit
*by P***F on January 6, 2026*

Iitem is a must have tool. Works great.

### ⭐⭐⭐⭐ A little bulky but good
*by D***B on October 11, 2025*

I got this as an alternative way of tightening my toilet seat screw nuts because hand tightening was not cutting it anymore. It feels a little bulky, but it is able to access hard to reach areas ( toilet seat screws and under the sink). Works as expected. The jaw is spring loaded- so you have to figure out what direction you are turning to properly place the tool for maximum effect. The jaws can be flipped for both clockwise and counter clockwise movements. The handle is basically a piece of a metal pin- not the best way to manipulate the tool but it gives you a hold point while you are adjusting the other end. After all- your tightening not torquing. The only thing I truly don’t like is the telescopic adjustment ( I thought I originally ordered the non- telescopic version) I see it as a potential failure point. It is a very basic spring assisted ball and socket. The end where the ball end- it is a solid piece ( minus the ball and spring) so there is no real way to access it. Overall-I would recommend this tool for the value conscious buyer.
