Description
Dowells Brass Cable Gland 50mm (2”) – Single/Double Compression
The Dowells Brass Cable Gland 50mm (2”) is an industrial brass cable-entry solution available in Single Compression and Double Compression configurations. It is intended for compatible electrical and industrial installations where secure cable entry, mechanical retention and appropriate cable termination are required.
The 50mm (2”) designation should not automatically be interpreted as a 50mm cable outside diameter. This is an important point when purchasing cable glands. The correct selection depends on the actual finished cable OD, cable construction, armour, gland configuration and required thread.
Dowells’ published Cable Gland Selection Chart demonstrates this clearly. Its Double Compression Brass Cable Glands are identified by suitable cable diameter ranges. For example, DBW-09 covers 41–46 mm, while DBW-010 covers 46–52 mm.

Dowells 50mm Single Compression Brass Cable Gland
The Dowells 50mm (2”) Single Compression Cable Gland is intended for compatible cable-entry applications where a single-compression configuration is specified.
When selecting the Single Compression version, do not choose the gland simply because the cable or project specification mentions “50mm.” Confirm the actual cable OD and the manufacturer’s applicable selection data.

Important Sizing Note
50mm does not necessarily mean a 50mm cable OD.
The gland’s nominal designation and the actual cable diameter are separate selection considerations. Always compare the actual cable OD with the manufacturer’s applicable gland range.

Dowells 50mm Double Compression Brass Cable Gland
The Dowells 50mm (2”) Double Compression Cable Gland is intended for applications requiring the corresponding double-compression arrangement, including applicable armoured-cable installations.
Dowells’ published selection chart lists its Double Compression Brass Cable Glands according to the actual cable diameter. The chart shows:
- DBW-08: 37–41 mm
- DBW-09: 41–46 mm
- DBW-010: 46–52 mm
- DBW-011A: 52–54 mm
- DBW-011: 54–61 mm
This illustrates why the correct product code should be selected according to the actual cable OD rather than simply choosing a “50mm” gland by name.
Double Compression Comparison Table

Single Compression vs Double Compression
Single Compression
Single Compression is appropriate when the cable and project specification call for a single-compression gland arrangement.
The selection should be based on:
- Actual cable OD
- Cable construction
- Required thread
- Application
- Manufacturer’s selection data
Double Compression
Double Compression is used where the installation requires the corresponding double-compression arrangement. Dowells’ published chart specifically categorizes its Double Compression Brass Cable Glands for armoured cable and provides cable-diameter ranges for each product code.
Quick Comparison
| Feature | Single Compression | Double Compression |
| Brand | Dowells | Dowells |
| Nominal size | 50mm (2”) | 50mm (2”) |
| Construction | Brass | Brass |
| Compression | Single | Double |
| Cable OD | Verify manufacturer range | Verify manufacturer range |
| Armour | Check application | Important |
| Thread | Verify | Verify |
| Main selection factor | Cable OD + construction + thread | Cable OD + armour + construction + thread |
| Typical selection approach | Match project specification | Match project specification and cable OD |
Do not select between Single and Double Compression merely because both are labelled 50mm (2”).
How to Select the Correct Dowells 50mm Cable Gland
1. Measure the actual cable OD
Use the cable manufacturer’s datasheet or measure the finished cable diameter.
This is especially important for the Dowells Double Compression range because the manufacturer’s selection chart is organized by suitable cable diameter.
2. Check cable construction
Determine whether the cable is:
- Armoured
- Unarmoured
- Single-core
- Multicore
- Power cable
- Control cable
3. Select Single or Double Compression
Use the cable construction and project specification to determine the required configuration.
4. Check the thread
Confirm the required gland thread and the corresponding entry on the equipment, panel, enclosure or junction box.
5. Match the cable OD to the manufacturer range
For example, Dowells’ published chart identifies DBW-09 for 41–46 mm and DBW-010 for 46–52 mm. Therefore, a cable close to 45mm and a cable close to 50mm may require different Dowells gland codes even though both may be described informally as requiring a “50mm-class” gland.
6. Check environmental requirements
For outdoor or demanding installations, confirm the exact manufacturer’s product specification, sealing requirements and project requirements before purchase.
Our Cable Gland Supplier India pillar guide covers these selection factors in more detail.

Frequently Asked Questions
1. What is a Dowells Brass Cable Gland 50mm (2”)?
It is a Dowells brass Cable Gland in the 50mm / 2-inch nominal size category, available in Single and Double Compression configurations for compatible cable-entry applications.
2. Does a 50mm Cable Gland fit a 50mm cable OD?
Not automatically.
The 50mm/2-inch designation should not be treated as a guaranteed 50mm cable-OD range. The manufacturer’s selection data must be checked against the actual cable OD.
Dowells’ Double Compression selection chart demonstrates this clearly by assigning different product codes to different cable-diameter ranges.
3. What cable diameter should I check for a Dowells 50mm Double Compression Gland?
Check the actual finished outside diameter of the cable.
Dowells’ chart includes DBW-09 for 41–46 mm and DBW-010 for 46–52 mm. The correct product code should therefore be selected according to the actual cable diameter rather than the nominal “50mm” description.
4. What is the difference between Dowells 50mm Single and Double Compression Cable Glands?
The two configurations use different compression arrangements and are selected according to the cable and installation requirements.
Double Compression is particularly relevant to applicable armoured cable installations, while Single Compression should be selected where the project specification calls for that arrangement.
5. Can I use the Dowells 50mm Single Compression Gland for armoured cable?
Do not assume suitability solely from the 50mm designation. Check the specific gland configuration and cable construction.
For an armoured cable requiring the applicable armoured gland arrangement, select the appropriate Dowells Double Compression configuration according to the cable diameter. Dowells’ selection chart identifies its Double Compression Brass Cable Glands for armoured cable.
6. Is 2 inches the same as 50mm for a Cable Gland?
50mm is commonly expressed as approximately 2 inches in product naming. However, the nominal designation should not be confused with the cable’s actual usable diameter range.
Always use the manufacturer’s selection information for the exact product.
7. How do I select a Dowells 50mm Cable Gland?
Check:
- Actual cable OD
- Cable construction
- Armoured/unarmoured
- Single/Double Compression requirement
- Thread
- Installation environment
- Manufacturer’s selection chart
Dowells’ own selection chart makes cable diameter a key selection parameter.
8. Does cable size in sq.mm determine the Cable Gland size?
No.
Cable conductor cross-section in sq.mm is not the same measurement as finished cable outside diameter. Cable construction, insulation, sheath and armour can all affect the final OD.
9. What thread should I use with a Dowells 50mm Cable Gland?
The thread must be checked against the specific gland configuration and equipment/enclosure entry. Do not assume that the “50mm” designation alone provides the complete thread specification.
10. Can two cables with different ODs use the same Dowells 50mm gland?
Only if both actual cable diameters fall within the manufacturer’s applicable cable range for that specific gland.
Dowells provides different product codes for different cable-diameter ranges, so the exact cable OD matters.
11. Is a brass Cable Gland suitable for industrial applications?
Brass Cable Glands are commonly used in electrical and industrial cable-entry applications. Actual suitability depends on the specific product, cable construction, equipment, thread and environmental requirements.
12. Where can I buy Dowells Brass Cable Gland 50mm in India?
