KNIPEX Cobra Water Pump Pliers, 250 mm, Nuts to 46 mm, Pipes to 50 mm, self-Locking, fine Adjustment by Button Push, Pipe Wrench, 87 01 250

well worth the price!! these grip and lock as it says. I haven't had these slip and don't think that it ever will. these have been great ever time I have used these. the design is great and is made of only high quality materials. these are the easiest to use because of the locking mechanism. they don't weigh much and are easy to use. I have put lots of force through these and they have never disappointed. I have seen them hold lots of weight through both me and others standing on these while testing them. therefore I don't think weight/for capacity is going to be a problem for anyone.

Great !!!! These don’t slip on anything grip well and always tighten up Light in the hand and easy to adjust

great bit of kit. perfect that theyre adjustable

Bought for son in law. Very happy. They are well made, versatile and very handy in any job he does.

Fully met my expectations. Good spanner.

Having used a cheap set of grips in the past that continuously slipped off bolts and handles that kept snapping closed on my fingers I gave up using grips like this until I was recommended to try the Knipex Cobra's. I bought the 250mm (10 inch) version as it was the most useful toolbox option for me. so what did I like about this tool? :The jaws are thin enough to reach into enclosed spaces :The teeth are incredibly sharp, they grip onto bolts and wont let go, this is easily better than using an adjustable spanner, although the grips will chew into soft metal. : once the grips are effectively locked onto a pipe you don't have to squeeze them any more, just maintain pressure on the top of the handle and the teeth do all the work gripping like crazy, you can stick an extension bar onto the top handle to maximize leverage. : The push button adjustment works really well and offers a superb range of sizes. : the teeth of the tool have been hardened to a significant degree, these wont deform or roll like a cheap tool. : No matter what level of adjustment the handles always have a gap so you will never pinch your fingers again!. :The handles have been hot dipped and will not slide off the tool. :The only thing I will say is that the teeth are directional, you have to flip the tool over if you want to go from tightening to loosening to get the best grip possible. Yes these are around a tenner more than most brands but I think it is money well spent, these have never let go on me and will take all the punishment you can dish out to them, phenomenal performance!.

Very nice grip and very lightweight tool.

Quality product lasts years, had some for 20 years till I lost them and they were still In great shape after heavy daily use. These are the best water pump pilers you can buy In my opinion. I daily use some cheaper non branded ones ordered through work and although they are solid they are not as good as knipex. So good I had to buy a 2. I have used other branded ones before ie rothenberger which are good but find myself always picking up the knipex for the best grip and staying locked at the size I need for the task Had some issues with the process of buying these. Not the seller or the products fault in anyway, the customer service was fantastic with this company, a phone call away and helped me right away.
