7880 Joker 4XL Self-setting insert spanner 41-55 mm, 14x18 mm - Wera 05020178001

Assembling and disassembling large fittings in plumbing, heating and ventilation requires the correct torque while wrench sizes keep changing. The 7880 Joker 4XL sets itself continuously to any size between 41 and 55 mm when attached and plugs directly into Click-Torque X torque wrenches with 14x18 mm mounting.

Benefits

• Automatically and continuously self-setting: the parallel jaws cover all metric and imperial dimensions from 41-55 mm or 1 11/16"-2 1/16".
• Gentle to the screw: the smooth parallel jaws provide seating stress and prevent the nut or screw head from rounding. The lever mechanism clamps the nut securely.
• Mechanical ratchet function in the jaw for fast and consistent screwdriving without removing the spanner.
• Return angle of only 30° when using the corner-width prisms in the jaw.
• Torque Advisor: the laser-engraved, abrasion-proof QR code determines the corrected torque value for the torque wrench and insert tool combination, with no formulas needed.
• Pin lock for safe working and rapid tool change, chrome vanadium steel for high loads.

Applications

Controlled tightening and loosening of hexagon nuts and bolts on large pipes and fittings in plumbing, heating and ventilation, wherever changing large wrench sizes are handled with a torque wrench.
