Dowells Brass Cable Gland 88mm (3-1/2″) – Single & Double Compression

The Dowells Brass Cable Gland 88mm (3-1/2″) is a large-size brass cable-entry solution intended for industrial electrical installations where reliable mechanical cable retention and controlled cable entry are required.

The 88mm (3-1/2″) designation refers to the nominal gland size/catalogue designation. It should not be used by itself to determine cable compatibility. Dowells’ published selection chart lists DGP10018 in the Single Compression range with a suitable cable diameter of 80.6–87.0 mm. The published Dowells price list identifies DGP10018 as the 88mm (3-1/2″) nominal size.

For a project requiring this size, the cable’s actual outside diameter, cable construction, armour arrangement, gland type and installation requirements should be checked before final selection.

Dowells 88mm Single Compression Cable Gland

The Single Compression version is intended for applications where the gland compresses and grips the cable sheath. It is suitable where the installation specification calls for a single-compression gland and the cable falls within the applicable manufacturer-specified selection range.

For the Dowells range, DGP10018 is the catalogue code associated with the 88mm (3-1/2″) nominal size in the published price list. Dowells’ selection chart lists the same code against 80.6–87.0 mm cable OD.

Single Compression Specifications

Specification	Details
Brand	Dowells
Product Type	Brass Cable Gland
Nominal Size	88mm
Imperial Size	3-1/2″
Compression Type	Single Compression
Dowells Catalogue Code	DGP10018
Dowells Selection Chart Cable OD	80.6–87.0 mm
Construction	Brass cable gland
Selection Basis	Actual cable OD and manufacturer selection data
Application	Industrial/electrical cable entry
Important	Verify cable OD, thread and cable construction before ordering

Note: The 80.6–87.0 mm figure is the selection-chart range for DGP10018; it should not be interpreted as an 88mm cable acceptance range.

Dowells 88mm Double Compression Cable Gland

The Double Compression configuration should be selected when the cable construction and installation specification require a double-compression gland, particularly for armoured cable applications.

Dowells’ selection documentation separates its Double Compression products into different families, including Double Compression Brass Cable Glands for unarmoured cable, Weather Proof Double Compression Brass Cable Glands for armoured cable, and DC-type medium-duty brass cable glands for armoured cable.

Consequently, it would be misleading to assign one universal Double Compression catalogue code to every 88mm cable without knowing the cable construction.

Double Compression Specifications

Specification	Details
Brand	Dowells
Product Type	Brass Cable Gland
Nominal Size	88mm
Imperial Size	3-1/2″
Compression Type	Double Compression
Cable Type	Depends on selected Dowells gland family
Application	Industrial/electrical cable entry
Selection Basis	Cable OD + construction + armour + gland family
Armour Requirement	Verify against cable construction
Accessories	Depend on selected gland configuration
Important	Confirm exact Double Compression model before purchase

Dowells’ own selection chart demonstrates why the exact Double Compression model must be chosen from the cable information rather than simply assuming that the nominal gland size determines the model.

Single Compression vs Double Compression – 88mm

Single Compression

Feature	Dowells 88mm Single Compression
Nominal size	88mm / 3-1/2″
Catalogue code	DGP10018
Dowells listed cable OD	80.6–87.0 mm
Primary function	Cable sheath gripping and retention
Selection	Actual cable OD
Suitable application	As specified for compatible cable/application
Best suited when	Project specification calls for Single Compression

Double Compression

Feature	Dowells 88mm Double Compression
Nominal size	88mm / 3-1/2″
Catalogue code	Depends on gland family
Cable selection	Depends on actual cable OD
Cable construction	Important
Armour	Important for armoured-cable versions
Primary function	Compression/sealing arrangement appropriate to selected gland design
Selection	Cable OD + construction + armour + application
Best suited when	Project specification requires Double Compression

Do not select between Single and Double Compression merely because the cable is physically large. The correct choice depends on the cable construction and the project specification.

How to Select the Correct 88mm Cable Gland

Before ordering a Dowells 88mm Cable Gland, check these points:

1. Measure the actual cable OD

Use the cable manufacturer’s datasheet or measure the complete cable outside diameter with an appropriate measuring instrument.

2. Don’t select only by conductor size

A cable marked in sq.mm describes conductor cross-sectional area. It does not by itself establish the complete cable OD.

3. Check whether the cable is armoured

Armoured and unarmoured cable constructions can require different gland designs.

4. Select Single or Double Compression correctly

Choose according to the cable construction and project specification rather than simply choosing the more expensive option.

5. Verify the thread

The gland’s thread/interface must match the enclosure, panel, junction box or equipment entry.

6. Check the manufacturer’s selection chart

For the 88mm nominal Dowells Single Compression gland, the published selection chart lists DGP10018 for 80.6–87.0 mm cable OD.

Typical Applications

The Dowells Brass Cable Gland 88mm can be considered for large industrial cable-entry applications where the selected gland specification matches the cable and equipment requirements.

Potential applications include:

• Industrial electrical panels
• Large junction boxes
• Switchgear installations
• Power distribution equipment
• Industrial control systems
• Electrical machinery
• Large cable-entry enclosures
• Infrastructure and project installations
• Heavy industrial cable-management systems
• Suitable armoured-cable installations where the selected Double Compression model is specified

The actual application suitability should be confirmed from the cable construction, equipment entry and project specification.

Frequently Asked Questions

1. What cable diameter fits a Dowells 88mm Cable Gland?

For the Dowells DGP10018 Single Compression selection, the published Dowells selection chart lists 80.6–87.0 mm cable OD. Therefore, an 88mm nominal gland should not automatically be assumed to accept an 88mm cable.

2. Is the Dowells 88mm gland actually for an 88mm cable?

Not necessarily. 88mm is the nominal/catalogue gland size. The actual cable acceptance range is determined by the manufacturer’s selection data. Dowells lists DGP10018 at 80.6–87.0 mm cable OD in its selection chart.

3. What is the difference between 88mm Single Compression and Double Compression?

Single Compression uses a single compression arrangement around the cable sheath. Double Compression uses a different gland construction and is available in Dowells families intended for specific cable constructions, including armoured and unarmoured applications. The correct version should be selected from the cable details and project specification.

4. Can I choose an 88mm Cable Gland only from the cable’s sq.mm size?

No. Cable conductor size alone is not sufficient. The complete cable outside diameter, construction, armour and other installation requirements should be checked before selecting the gland.

5. Can the same Double Compression gland be used for every 88mm cable?

No. Dowells provides different Double Compression gland families and selection ranges. Armoured and unarmoured cables can require different gland configurations.

6. How do I know whether I need Single or Double Compression?

Start with the cable construction and project specification. If the cable is armoured, verify the applicable Dowells armoured-cable gland family and selection range. Do not select the compression type solely from the nominal 88mm size.

7. Does the 3-1/2″ designation mean the cable diameter is 3-1/2 inches?

No. The 3-1/2″ designation identifies the nominal gland size. It should not be treated as the cable’s actual outside diameter. This distinction is important when selecting large cable glands.

8. What information should I send when asking for an 88mm gland?

Ideally provide:

• Cable manufacturer
• Cable type
• Number of cores
• Conductor size
• Complete cable OD
• Armoured/unarmoured status
• Required gland type
• Thread requirement
• Quantity
• Application/project specification

This allows the correct gland model to be checked instead of relying only on the 88mm label.
