RS PRO Extendable Socket Wrench

Introducing RS PRO’s extendable ratchet socket wrench. This high quality, reversible and lightweight ratchet has a compact head for access into tight and enclosed areas, as well as an extendable arm for fasteners that are further away and require an extended reach. The ratchet head is sealed which means it is dustproof and has a maintenance-free mechanism, which allows for working in environments where dust and debris are commonplace, without compromising on the quality of the tool and overall intended use. The ergonomic comfort grip has been created to be resistant to liquids and greases in different environments, for example, areas with chemicals and solvents, making it an ideal tool for any user to have, regardless of whether the intended use is at home or on a working site or workshop.

Features and Benefits:

• The compact ratchet gives easy access in tight spaces with no loss of torque
• The extendable handle allows for better reach when working in areas where fasteners are further away - 215mm to 315mm
• Maintenance-free 3/4 inch sealed ratchet head that allows for longer lasting tool life and consistent quality in completed work
• Ultra-compact square drive head that fits a variety of metric and imperial socket sizes making it a versatile and essential piece of equipment for everyday usage
• 72-tooth mechanism with 5° increments for small angle ratcheting ideal for tight spaces
• Reversible switch for quick direction change with minimal user adjustment
• Ergonomic, soft-grip handle for superior grip and continued comfort
• Chrome finish for easy cleaning and corrosion resistance


Socket Wrenches are a type of wrench or ratchet designed to work with sockets attached to the head of the wrench.

Sockets wrenches and are commonly used by professionals such as car mechanics, engineers, builders and DIY enthusiasts. They are a valuable hand tool, saving a lot of time and minimising effort for the user.

How does a ratchet spanner work?

A ratchet spanner or wrench uses a mechanism which allows an open-ended, flare or ring head to turn a fastener in one direction but not the other while remaining fitted to the fastener head. By turning the spanner over or flicking a lever, it changes the direction of movement.

Does this spanner feature a reversing lever?
