## Long description

The Knipex 87 21 300 slip-joint pliers are designed for gripping, holding and turning a wide range of components in plumbing, mechanical and general maintenance tasks. With a total length of 300 mm and a compact profile, these pliers offer mechanical advantage and precise handling for pipes, fittings and fasteners. The tool features a slip-joint adjustment to change jaw capacity quickly and a hardened gripping surface for reliable contact with metal and non-metal parts.
Advantages
These slip-joint pliers combine robust construction with a versatile jaw geometry that accommodates different diameters up to the specified maximum pipe capacity. The 300 mm length delivers balanced leverage while remaining manoeuvrable in confined spaces. A hardened chewing surface and accurate joint tolerances improve grip security and reduce slippage when turning nuts, bolts or round stock.

Key specifications

Maximum pipe diameter capacity: 70 mm
Nut capacity: up to 60 mm
Weight: approximately 530 g
Slip-joint adjustment for variable jaw opening
Hardened gripping surfaces for improved bite and wear resistance
How to use
Position the pliers so the jaws fully engage the workpiece, then adjust the slip-joint to achieve the correct jaw opening for the required diameter. Apply steady pressure to the handles to hold or turn pipes, fittings or fasteners; avoid sudden or excessive force that could damage the tool or the workpiece. For safe operation maintain a firm two-handed grip and work with the jaws perpendicular to the axis of the object where possible.
Usage recommendations
Use the pliers within the stated maximum capacity to avoid overstressing the joint. Inspect the gripping surfaces regularly for wear and keep the joint clean and lightly lubricated to ensure smooth adjustment. Do not use these pliers as a hammer or for cutting hardened fasteners; select an appropriate tool if high torque or cutting is required.
