Shifting Spanner 300mm (12") – Adjustable Jaw 0–33.5mm – Drop Forged CrV

A 300 mm (12") shifting spanner with a 0–33.5 mm jaw — one adjustable wrench that covers flare nuts, valve caps and service fittings across every install.

The wide jaw range swallows everything from a 1/4" flare nut to a large service valve body, and the smooth adjusting worm holds its setting under load instead of creeping open mid-pull. Drop-forged steel gives it the backbone for stubborn, weathered fittings on rooftop units.

Perfect for

• Flare nuts and service valve work on aircon installations
• Backing up fittings while torquing the opposite side
• General plumbing and mechanical fastening

Features

• Smooth-adjusting jaw with clear size scale
• Jaw holds its setting under load
• Drop-forged body with comfortable grip

Good to know

• Always pull towards the fixed jaw — the strong direction for any shifter
• Snug the jaw fully onto the flat before loading, or the fitting rounds
• Two shifters back-to-back is the correct way to tighten flare joints

Specifications

• Length: 300 mm (12")
• Jaw capacity: 0–33.5 mm
