IRWIN Locking Chain Clamp Extension Chain – Sturdy and Reliable
The IRWIN Locking Chain Clamp Extension Chain (20R, 18-Inch, 40EXT) is an incredibly versatile tool that has become a staple in my workshop. As someone who frequently works on irregularly shaped objects and hard-to-clamp materials, this chain clamp has proven to be indispensable for securely holding items in place while I work. Here's what I love about it: Durable and Strong The quality of construction is immediately noticeable. The clamp feels sturdy and well-built, with durable metal that stands up to tough jobs. The chain itself is solid and doesn’t feel flimsy or prone to breaking, even when you’re applying a lot of pressure. Whether you’re working with pipes, cylinders, or oddly shaped items, this clamp holds up well, securing items in place without slipping. Versatile Clamping One of the biggest advantages of this tool is its versatility. Unlike standard clamps that are limited to flat or rectangular objects, the chain design allows you to clamp around anything that doesn’t have a uniform shape. This has been a game-changer for me when working with round pipes, irregular metalwork, and large items that wouldn’t fit in a traditional clamp. The 18-inch length gives plenty of range, allowing you to work on a variety of different-sized objects with ease. Excellent Locking Mechanism The locking mechanism is one of the standout features of this clamp. Once you’ve wrapped the chain around the object and tightened it, the clamp locks securely into place and stays locked until you release it. I’ve never experienced any slippage, and it provides a really strong hold, which is crucial when you’re working on more precise projects or heavy-duty tasks. The quick-release feature is smooth and easy to use, making adjustments hassle-free. Comfort and Usability The clamp is not only reliable but also easy to use. It has a comfortable handle, and the tension can be adjusted easily, even while wearing gloves. The design allows for a firm grip, and I’ve never experienced any discomfort, even when using it for extended periods of time. I also appreciate how easy it is to reposition or adjust the chain as needed, allowing for quick adjustments during a project without much downtime. Value for Money Given the level of durability, versatility, and ease of use, the IRWIN Locking Chain Clamp is priced very reasonably. For professionals and DIY enthusiasts alike, this is a tool that delivers excellent value for the price. Its long-lasting build means I don’t foresee needing to replace it any time soon, which only adds to its appeal. Final Thoughts The IRWIN Locking Chain Clamp Extension Chain is an outstanding tool that offers strength, durability, and versatility for a wide range of projects. Whether you're working on irregularly shaped objects or simply need a reliable clamp for heavy-duty tasks, this chain clamp performs beautifully. It’s easy to use, locks securely, and feels like it’s built to last. Highly recommended for anyone in need of a dependable clamping solution!

Good quality and is an exact match to the chain ...
Good quality and is an exact match to the chain used on the Irwin Tools Vice Grip 9-Inch Locking Chain pliers. Bought this extension to add to the Irwin Tools Vise Grip 9 inch locking chain pliers to give extra girth. This unit comes with a pin to use in adding to the afore-mentioned pliers existing chain and is an exact match. There are no instructions on how to use the pin to add to the chain on the pliers so you have to already sort of know what you are doing. I managed to do the operation reasonably well and was satisfied with the results. Someone ought to do a you-tube video of this to help those who don't have a clue, but unfortunately it won't be me because I have already put it together and it won't come apart once together.

Great extension
I often use these chain wrenches as a prop while I’m welding pipe. This extension added on to a 48” chain wrench allows me to have an adjustable point to get stable and comfortable welding 16” pipe in position.
