Cover the edges of 20mm or 25mm holes with these open rubber grommets. Made from flexible and durable rubber, they are perfectly suited for untapped holes of 1.6mm thickness.

By inserting the grommet into a cut-out, the sharp or rough edges of the hole are covered, improving safety and preventing friction damage to wires or cables. The open style allows for easier insertion around already-installed cables. The black colour provides a smart, neat, and professional finish.

• Available in 20mm or 25mm sizes – pack of 100
• Protects cables – covers rough or sharp edges
• Prevents friction damage – improves safety and longevity of cables
• Open-ring style – allows for easier installation around existing cables
• Neat finish – black colour for a smart appearance
