Multi-hole Cable Glands: How to Choose 2-hole, 3-hole and Custom Inserts
Multi-hole cable glands route several small cables through one enclosure entry point. The key is matching thread size, hole count and each cable diameter.
What Is a Multi-hole Cable Gland?
A multi-hole nylon cable gland uses an insert with several cable holes so multiple sensor, signal or control cables can enter an enclosure through one threaded gland.
This is useful when a cabinet has limited panel space or when the wiring layout needs to stay compact and organized.
2-hole, 3-hole or Custom Insert?
| Layout | Typical use | RFQ detail needed |
|---|---|---|
| 2-hole cable gland | Two small sensor or signal cables entering one box | Thread size and diameter of both cables |
| 3-hole cable gland | Three control or instrument cables in a compact enclosure | Thread size and diameter of each cable |
| 4-hole or custom insert | Project-specific wiring layout | Drawing, hole count, cable diameters and sealing requirement |
Key Selection Factors
Thread Size
The gland thread must match the enclosure hole. Metric and PG thread families can be discussed according to the cabinet drawing.
Each Cable Diameter
Do not send only the largest cable size. Each cable diameter matters because the insert needs to seal every cable path.
Material and Color
PA nylon is common for multi-hole glands. Black and light gray are common colors for enclosure accessory programs.
Installation Environment
Outdoor electrical boxes, automation panels and industrial housings may have different sealing expectations. Share the application so the quote can be checked properly.
When Not to Use a Multi-hole Cable Gland
If the cables are large, shielded or require separate strain relief paths, individual cable glands may be more suitable. For shielded cables, compare the requirement with EMC brass cable glands.
