Specs & description

Description

  • ✅ PIPE SIZE, NOT NUT WIDTH (IMPORTANT) – Marked 1/2″ & 3/4″, which refers to tap pipe size, not the visible nut measurement. The spanner will look larger than expected — this is correct for tap backnuts.

  • ✅ DUAL-ENDED BOX SPANNER – One tool covers both common tap sizes (1/2″ & 3/4″), reducing the need for multiple tools.
  • ✅ TOMMY BAR ACCESS HOLES – Side holes allow use with a tommy bar or screwdriver for added leverage in tight spaces.
  • ✅ HEAVY-DUTY CHROME-PLATED STEEL – Durable, corrosion-resistant construction for repeated plumbing and DIY use.
