Description
Extended Series: Lengthened Nylon Cable Glands (Metric & PG)
1. Product Overview
The Clifnor Extended Series is specifically engineered for applications requiring a longer thread reach, such as thick-walled junction boxes, double-layered enclosures, and heavy-duty industrial castings. Manufactured from high-grade Halogen-Free Nylon, these glands provide superior strain relief and a permanent IP68 environmental seal. The elongated thread ensures a secure mechanical lock even in non-standard mounting conditions.

3. Engineering & Design Advantages
-
Extended Reach Design: Featuring a significantly lengthened thread profile to accommodate mounting through thick enclosure walls or insulation layers where standard glands fail to engage the locknut.
-
Optimized Clamping Geometry: The specialized internal claw design provides ultra-strong stretching resistance, protecting internal terminations from accidental cable pull-out.
-
Environmental Shielding: Highly resistant to salt spray, weak acids, alkalis, alcohols, and industrial greases. The NBR/EPDM sealing system maintains airtight integrity over long-term exposure.
-
Integrated Seal Protection: Designed to maintain a high-pressure seal against the cable jacket without causing permanent deformation or cold flow of the insulation.
4. Strategic Industry Applications
-
Industrial Castings: Secure cable entry for thick-walled aluminum or steel motor housings and gearboxes.
-
Telecommunications: Outdoor 5G base stations and signal boosters requiring deep-threaded entry points.
-
Heavy Infrastructure: Traffic control systems, railway signaling, and tunnel lighting panels.
-
Custom Enclosures: Double-walled or insulated electrical cabinets where standard thread lengths are insufficient.
