How to Select a Metric Multi-Hole Cord Grip

1

Confirm the metric thread

Match the fitting thread to the enclosure entry, from M12 x 1.5 through M63 x 1.5 in this chart.

2

Count the cable paths

Select an insert with the required number of holes. Solid plugs are included for closing unused metric openings or for custom drilling your own holes.

3

Check every cable diameter

Compare each cable's outside diameter with the listed hole size.

4

Choose the body material

Pick black or gray nylon for a lightweight body, or nickel-plated brass when a metal fitting is preferred.

Fit tip: Thread size and hole diameter are the most important specifications. The thread must fit the enclosure opening, while each insert hole must fit the cable passing through it.

Dimensions are provided for comparison. Confirm cable outside diameter, sealing requirements, and certifications on the product page before ordering. Products marked ATEX should be evaluated against the requirements of the specific hazardous-location installation.

Body Material Quick Reference

Black or Gray Nylon Plastic

A lightweight choice for many control cabinet and equipment enclosure installations. Select the color that best matches the enclosure or wiring standard.

Nickel-Plated Brass

A metal-body option for installations where durable mechanical construction is preferred. Confirm sealing and enclosure requirements for the application.

ATEX-Marked Options

Red ATEX badges identify the ATEX approved cord grips. Review the current approvals on the product page before specifying it for a hazardous area.

Why Use a Multi-Hole Cable Gland?

When several sensor leads or small control cables must enter the same enclosure, a multi-hole strain relief fitting consolidates them into one threaded entry. This can reduce the number of enclosure openings while keeping each cable organized at the entry point.

These Sealcon metric cord grips are a practical fit for compact control panels, junction boxes, and machine-mounted enclosures where entry space is limited. The correct configuration depends most on the enclosure thread and the outside diameter of every cable.

Metric Multi-Hole Cable Gland FAQ

What is a multi-hole cable gland?

It is a strain relief fitting with several openings in one insert, allowing multiple wires or cables to pass through a single threaded enclosure entry.

How do I choose the correct Sealcon multi-hole fitting?

Start with the enclosure's metric thread, then match the number of cable paths and each cable's outside diameter. On the product page, review the complete specifications and required approvals.

What is the difference between the thread size and hole diameter?

The thread size matches up with the size of the enclosure entry that will accept the fitting. The hole diameter refers to the size of each cable path in the sealing insert and must be checked against the cable itself.

Why are solid plugs included?

A solid plug closes an unused metric opening and provides a convenient option when a planned cable entry is not yet needed. Holes can also be drilled in case a custom hole size or multiple hole sizes are required.
