Overview
The KNIPEX 87 01 125 SBA is a compact 5 inch adjustable plier with plastic handles, weighing just 3.12 ounces. Its small size and light weight make it suited to tight spaces and fine adjustment work rather than heavy pipe jobs.
The 125 in the model number points to a 5 inch overall size, notably smaller than the brand's larger Cobra style pliers. That makes it a pocket or toolbox companion rather than a primary plumbing tool, useful where a full size adjustable plier will not fit. The SBA designation in Knipex naming typically marks a smaller, precision focused variant within the same plier family.
- 5 inch (125mm) compact size
- 3.12 ounce weight
- Plastic handle grip
- Self adjusting jaw
Who it's for
Fits users who need a small adjustable grip tool for electronics, hobby work, or tight mechanical spaces. Less useful for anyone gripping large pipes or fittings that need a wider jaw opening.

Performance notes
