Overview
KNIPEX 87 41 250 RAP is a 10 inch Cobra style adjustable plier with plastic dipped handles, weighing 0.75 pounds. It suits plumbers, mechanics, and DIY users who need a self adjusting grip on pipes, nuts, and fittings of varying sizes.
The number 250 in the model name marks its jaw opening capacity in millimeters, giving it enough reach for larger pipe and fitting work without stepping up to a full size wrench set. Plastic dipped handles add a non slip grip layer over the tool steel body. Pliers in this Knipex line are known in the trade for tight tolerances between the jaw and the adjustment rack, which helps keep the jaw from slipping mid grip.
- 10 inch (250mm) adjustable jaw
- Plastic dipped handle grip
- 0.75 pound weight
- Knipex tool steel construction
Who it's for
Fits users who already reach for adjustable pliers on plumbing and light mechanical jobs and want one tool that adjusts fast between sizes. Less suited to anyone who mainly needs a fixed size wrench for repeated identical fasteners.
Strengths and trade-offs
Drawn from this product's published specifications.
- Self adjusting jaw covers multiple sizes
- Plastic dipped handles cushion grip
- Compact 0.75 pound weight for one handed use
- No reviews on file to confirm long term durability
- Plastic handle dip may wear with heavy daily use
Performance notes
The self adjusting jaw locks into a tooth pattern along the handle, so it holds its set width under load instead of creeping open. Plastic dipped handles cushion grip pressure during extended use.
