Description
Dowells Brass Cable Gland 28mm (1-1/8”) – Single & Double Compression
The Dowells Brass Cable Gland 28mm (1-1/8”) is designed for cable-entry applications where the gland must provide secure mechanical retention and reliable cable termination. Dowells’ current catalogue identifies 28mm (1-1/8″) as a single-compression gland size with catalogue number DGP10007. The same catalogue also lists Dowells double-compression armoured glands with selection based on cable overall diameter and thread.
For engineers, electrical contractors, panel builders and industrial purchase teams, the important point is that 28mm is a gland designation—not automatically the cable’s outside diameter. Cable OD, construction, armour and required thread should be checked before ordering.

Dowells 28mm (1-1/8”) Single Compression Cable Gland
The Dowells 28mm Single Compression Brass Cable Gland is listed in the Dowells catalogue as DGP10007. It belongs to the single-compression brass cable-gland range and is identified with the 1-1/8″ size designation.
Single compression is generally selected when the installation requires the gland to secure and grip the cable at the entry point without the same armour-clamping arrangement used by a double-compression armoured gland.
Single Compression Specifications
| Specification | Details |
| Brand | Dowells |
| Product Type | Brass Cable Gland |
| Compression Type | Single Compression |
| Size | 28mm |
| Imperial Size | 1-1/8” |
| Catalogue No. | DGP10007 |
| Material | Brass |
| Application | Cable entry / termination |
| Selection Basis | Cable OD, construction, thread & application |
The DGP10007 designation and 28mm / 1-1/8″ size are supported by the Dowells catalogue.
Dowells Double Compression Cable Gland
A Double Compression Cable Gland is intended for applications where the cable construction and installation require compression/retention at the cable entry and appropriate treatment of the cable’s inner and outer sheath/armour arrangement.
Dowells’ current catalogue lists its double-compression armoured glands according to suitable overall cable diameter and thread. For example, its catalogue includes several configurations around the 1-1/8″ and adjacent thread sizes, demonstrating why the gland should be selected from the actual cable dimensions rather than by nominal size alone.
Double Compression Specifications
| Specification | Details |
| Brand | Dowells |
| Product Type | Brass Cable Gland |
| Compression Type | Double Compression |
| Nominal Size Reference | 28mm / 1-1/8” |
| Cable Type | Select according to cable construction |
| Material | Brass |
| Selection Basis | Cable overall diameter, armour, thread & application |
| Installation | Suitable compatible cable-entry application |
Important: Do not use “28mm” as a substitute for the actual cable OD. Dowells’ published double-compression catalogue uses suitable overall diameter as a selection parameter.
Single Compression vs Double Compression
Single Compression Comparison
| Feature | Dowells 28mm Single Compression |
| Brand | Dowells |
| Size | 28mm (1-1/8”) |
| Catalogue reference | DGP10007 |
| Construction | Brass cable gland |
| Compression | Single |
| Main selection factor | Cable OD + compatible thread |
| Cable construction | Verify against project requirement |
| Best suited for | Compatible cable-entry installations |
Double Compression Comparison
| Feature | Dowells Double Compression |
| Brand | Dowells |
| Size reference | 1-1/8” / applicable gland configuration |
| Construction | Brass cable gland |
| Compression | Double |
| Cable selection | Actual overall cable diameter |
| Armour consideration | Required for armoured-cable applications |
| Thread | Must match installation requirement |
| Best suited for | Compatible armoured cable-entry applications |
Buying tip: The two configurations should not be treated as interchangeable simply because they have a similar nominal size. Cable construction and the required termination method determine which type is appropriate.

How to Select the Correct Dowells Cable Gland
Before ordering a Dowells 28mm Cable Gland, confirm:
- Actual cable overall diameter from the cable datasheet or by measurement.
- Whether the cable is armoured or unarmoured.
- Whether single or double compression is required.
- Required thread type and thread size.
- Indoor, outdoor or other environmental conditions.
- Whether the installation requires additional accessories.
- Whether the selected gland’s published cable range matches the actual cable.
This is particularly important because cable-gland sizing is not determined only by conductor cross-section. Our Cable Gland Supplier India buying guide explains the main selection factors engineers and procurement teams should check.

Frequently Asked Questions
1. What is a Dowells Brass Cable Gland 28mm (1-1/8”)?
It is a Dowells brass cable-gland size identified as 28mm / 1-1/8″. Dowells’ catalogue lists the single-compression version as DGP10007.
2. What is the Dowells 28mm Single Compression Cable Gland catalogue number?
The Dowells catalogue identifies the 28mm (1-1/8″) Single Compression Gland as DGP10007.
3. Does 28mm mean that my cable has to be exactly 28mm outside diameter?
No. The 28mm designation should not automatically be interpreted as the acceptable cable OD. Cable-gland selection should be based on the manufacturer’s applicable cable range, actual cable OD, construction and thread.
Dowells’ catalogue demonstrates this clearly by publishing suitable overall diameter ranges for its gland products.
4. What is the difference between Single Compression and Double Compression Cable Glands?
Single compression and double compression glands use different termination arrangements. Double-compression armoured glands are selected where the installation requires appropriate treatment of the cable’s inner/outer sheath and armour. The cable construction should therefore be checked before selecting the gland.
5. Can I use a 28mm Cable Gland for any 28mm cable?
No. Cable OD is only one part of the selection process. You should also check cable construction, armour, gland configuration and thread. A cable with a nominal designation that appears similar to the gland size may still require a different gland.
6. Is Dowells 28mm Cable Gland suitable for armoured cable?
The appropriate Dowells configuration depends on the cable and gland series. For an armoured cable, select the applicable double-compression armoured gland configuration rather than assuming that the 28mm single-compression model is suitable.
7. How do I know whether I need Single or Double Compression?
Check the cable construction and project specification. If the cable is armoured and the installation requires armour clamping/appropriate armour termination, a suitable double-compression armoured configuration may be required. For the correct selection, provide the cable’s overall diameter and construction.
8. What information should I provide when ordering a Dowells Cable Gland?
Ideally provide:
- Cable overall diameter
- Armoured/unarmoured
- Single-core/multicore
- Required gland type
- Thread requirement
- Quantity
- Application/project requirement
This allows the correct gland configuration to be checked before dispatch.
9. Where can I buy Dowells Brass Cable Gland 28mm in India?
Thunderbolt Electromech India Pvt. Ltd. lists Dowells Single/Double Compression Brass Cable Gland 28mm (1-1/8″) and other Dowells sizes.
10. Is 28mm Cable Gland the same as M28?
Not necessarily. Nominal gland size, thread designation and cable-entry dimensions should not be assumed to be interchangeable. Always verify the required thread and manufacturer’s catalogue before ordering.
