The GTG3225 is a 32mm grey meter tails gland designed for larger installations requiring two 25mm 6181Y meter tails and one 16mm 6491X green/yellow earth conductor. It provides a secure, tidy, and compliant entry point into consumer units, isolator boxes, and meter cabinets.

Using a dedicated tails gland reduces the risk of cable insulation damage, maintains the enclosure’s IP integrity, and ensures a professional finish. The GTG3225 is particularly suited to high-demand domestic installs and small commercial jobs where 25mm tails are specified by the DNO or required due to load demand. For smaller installs, see our GTG3216 Tails Gland.

Key features:

• Pre-drilled entry points for 2 × 25mm meter tails (6181Y) + 1 × 16mm earth (6491X)
• 32mm gland body – fits standard consumer unit/meter box knockouts
• Manufactured from UL-approved PA66 nylon, halogen-free
• Rated to IP68 for dust and water protection
• Provides mechanical strain relief and neat cable management
• Flame-retardant (UL94V-2) for added safety

For electricians working to the 18th Edition, this gland is a reliable and compliant way to terminate and protect 25mm meter tails during new installs or board upgrades. Pair with a 100A Meter Isolator and 100A Terminal Block for a complete meter connection setup.
