Lapp Black Fibreglass Reinforced Polyamide Cable Gland Locknut, PG21 Thread, IP68

This cable gland locknut secures cable glands where only a pass-through aperture exists, enhancing fixation and reducing vibration-induced loosening in industrial enclosures. Manufactured from glass-fibre reinforced polyamide, it is intended for use with threaded cable glands and offers suitability for harsh or confined installation points requiring a reliable mechanical lock.

• Fibreglass reinforced polyamide construction provides mechanical strength and light weight
• Rated for continuous operation up to 100°C for elevated-temperature environments
• Withstands down to -20°C for cold-condition performance
• IP68 classification ensures protection against dust and prolonged water immersion
• Hexagonal form enables spanner-tight mounting for improved vibration resistance

• Suitable for securing cable glands on control cabinet pass-throughs
• Ideal for industrial automation junction boxes exposed to moisture
• Used with threaded glands in electrical distribution enclosures
• Can be used for retrofitting glands where only a plain hole exists
• Suitable for machinery panels requiring enhanced vibration security

It is produced for a PG13.5 threaded Interface commonly used in industrial cable glands.

A black finish is provided to match darker enclosures and reduce Visual contrast.

UL recognition applies only when combined with UL-approved polyamide cable glands as part of the assembly.

The hexagonal outer profile allows tool access and secure torque application where clearance is limited.
