Proline Tools 36804 spanner wrench

Adjustable hook wrench with jaw and swivel Proline 120–180 mm is a hand tool designed for tightening and loosening round nuts, retaining rings and threaded collars with diameters in the 120–180 mm range. The tool combines an adjustable jaw opening and a swivel joint to provide access at different angles, making it suitable for workshop maintenance and repair tasks where standard wrenches cannot reach or where light angular adjustment is required.

Advantages

The adjustable jaw allows a secure fit on a range of diameters without the need for multiple fixed-size tools. The swivel joint increases accessibility in confined or awkward spaces, enabling the operator to work on components mounted at various angles. Robust construction and hardened contact surfaces improve wear resistance and maintain reliable gripping force under repeated use. The simple adjustment mechanism speeds up size changes and supports efficient workflow in maintenance and service environments.

Suitable for

• Plumbing work involving large threaded collars and locknuts
• Machinery assembly and disassembly where round nuts or retaining rings are used
• Industrial equipment maintenance requiring adjustable reach and angle
• Workshop general maintenance and repair tasks

Key specifications

• Adjustable jaw opening: 120–180 mm
• Swivel joint for angular access
• Material: hardened steel contact surfaces with durable body construction
• Intended use: manual tightening and loosening of round nuts, retaining rings and threaded collars

How to use

Select the approximate jaw opening by rotating the adjustment mechanism until the hook and jaw accommodate the target nut or collar. Position the hook so that the contact surface engages the nut or ring securely, then angle the swivel joint as needed to create a comfortable working position. Apply steady manual force to tighten or loosen the component; avoid sudden jerks to prevent slipping. After use, retract the jaw to its minimum setting for storage and inspect contact surfaces for wear before subsequent use.

Usage recommendations

For safe and effective operation, verify that the component diameter falls within the 120–180 mm range before applying the hook wrench. Use moderate, controlled force and keep hands clear of pinch points when adjusting the jaw or swivel. Regularly inspect the tool for wear or damage and maintain clean, dry storage to prolong service life.
