Description
Dowells Brass Cable Gland 63mm (2-1/2”) – Single/Double Compression
The Dowells Brass Cable Gland 63mm (2-1/2”) is designed for industrial cable-entry applications where the correct gland size, cable diameter, cable construction and enclosure entry must be considered together.
This product is available in Single Compression and Double Compression configurations. Although both are identified with the 63mm (2-1/2″) size designation, they should not be selected simply because the cable is described as a “63mm cable.” The actual cable outside diameter and the manufacturer’s applicable selection range are important.
For a broader explanation of cable-gland selection, see Thunderbolt’s Cable Gland Supplier India: 15 Expert Tips to Choose the Right Cable Gland for Industrial Projects.
Dowells 63mm Single Compression Cable Gland
The Dowells 63mm Single Compression gland corresponds to DGP10014 in the Dowells catalogue. The manufacturer’s brochure lists DGP10014 for a 57.1–61.5 mm cable diameter. This is an important distinction because the product’s 63mm designation is not the same thing as the cable’s outside diameter.
The Single Compression configuration is suitable when the installation specification calls for the corresponding Dowells single-compression gland and the actual cable dimensions fall within the manufacturer’s stated range.

Dowells 63mm Double Compression Cable Gland
For the Dowells 63mm (2-1/2″) Double Compression configuration, the current Dowells selection data identifies DC-2.1/2 / DGP10049 for an overall cable diameter of 54.6–63.5 mm. The 2026 Dowells price-list data also identifies DGP10049 as the DC-2.1/2 configuration with a 2-1/2″ nipple.
This configuration is listed under Dowells’ Double Compression Brass Cable Glands for armoured cable. The double-compression selection therefore needs to take cable construction and armour into account, not just the nominal gland number.

How to Choose the Correct Dowells 63mm Cable Gland
Selecting a cable gland only from the cable’s conductor size is a common purchasing mistake. The gland interfaces with the complete finished cable, so its overall diameter and construction matter.
1. Check the actual cable OD
Use the cable manufacturer’s datasheet or measure the finished cable outside diameter.
For example, Dowells lists:
- DGP10014 Single Compression: 57.1–61.5 mm
- DGP10049 Double Compression: 54.6–63.5 mm
These are manufacturer-specific selection ranges and should not be replaced with an assumed “63mm cable” rule.
2. Identify the cable construction
Confirm whether the cable is:
- Armoured
- Unarmoured
- Single-core
- Multicore
- Power cable
- Control cable
- Other industrial cable construction
3. Decide Single or Double Compression
If the project specification calls for Single Compression, select the applicable Dowells Single Compression gland.
For an armoured-cable installation requiring Double Compression, select the appropriate Dowells Double Compression configuration.
4. Verify the enclosure entry
The gland must match the entry/thread arrangement of the panel, junction box, switchgear, equipment or enclosure.
5. Confirm environmental requirements
For outdoor, dusty, wet, corrosive or otherwise demanding installations, verify the required sealing and ingress-protection requirements against the applicable product documentation.

Common Buying Problems With 63mm Cable Glands
| Customer Problem | Common Reason | Better Approach |
| Gland does not fit cable | Cable OD not checked | Measure actual cable OD |
| 63mm gland assumed to fit 63mm cable | Nominal size confused with cable diameter | Check manufacturer selection range |
| Wrong compression type ordered | Cable construction not considered | Confirm Single/Double Compression |
| Gland does not fit panel | Entry/thread not verified | Check enclosure entry |
| Wrong gland selected from cable sq.mm | Conductor size used alone | Check complete cable OD |
| Armoured cable gets wrong gland | Armour requirement ignored | Check cable construction and project specification |
This selection logic is also consistent with recurring electrician discussions online: cable-gland selection commonly involves identifying the actual cable diameter and matching the gland to the installation rather than relying only on a nominal number.

FAQs – Dowells Brass Cable Gland 63mm
1. What is a Dowells 63mm cable gland?
A Dowells 63mm (2-1/2″) Cable Gland is a brass cable-entry gland available in different configurations. Dowells lists DGP10014 for its 63mm Single Compression size and DC-2.1/2 / DGP10049 for its Double Compression armoured-cable configuration.
2. Does a 63mm cable gland fit a 63mm diameter cable?
Not automatically. The 63mm designation is the gland’s nominal size. Dowells lists DGP10014 Single Compression for 57.1–61.5 mm, while DGP10049 Double Compression is listed for 54.6–63.5 mm overall cable diameter.
3. What cable diameter fits the Dowells 63mm Single Compression gland?
Dowells’ published brochure lists DGP10014 for 57.1–61.5 mm cable diameter. Always verify the latest applicable manufacturer selection data before ordering.
4. What cable diameter fits the Dowells 63mm Double Compression gland?
Dowells’ selection chart lists DGP10049 for 54.6–63.5 mm overall cable diameter. The 2026 price list identifies the corresponding catalogue designation as DC-2.1/2″.
5. What is the difference between Single and Double Compression?
Single and Double Compression are different gland configurations. The correct choice depends on cable construction and the project specification. Dowells specifically lists its medium-duty Double Compression range for armoured cable.
6. Is Dowells 63mm Double Compression suitable for armoured cable?
Yes. Dowells’ selection chart identifies the DGP10036–DGP10054 range as Double Compression Brass Cable Glands for Armoured Cable, including DGP10049 for 54.6–63.5 mm.
7. Can I select a cable gland according to cable sq.mm?
It is not recommended to select the gland from conductor size alone. The finished cable’s overall diameter and construction are important. Dowells provides specific cable-diameter ranges for its gland codes.
8. What thread is associated with Dowells DC-2.1/2?
The 2026 Dowells price-list data identifies DC-2.1/2″ / DGP10049 with a 2-1/2″ nipple. Verify the actual enclosure entry and current manufacturer documentation for the installation before ordering.
9. How do I know whether I need 63mm Single or Double Compression?
Start with the cable construction and project specification. Then check the actual cable OD against the applicable Dowells selection table. If the specification requires a Double Compression gland for an armoured cable, do not substitute a Single Compression gland merely because both carry a 63mm nominal designation.
10. Is the Dowells 63mm gland suitable for every large power cable?
No. Cable construction and outside diameter vary between cable designs and manufacturers. The correct gland must be selected against the applicable Dowells range and the actual cable dimensions.

Possible reasons include:
- Cable OD is outside the gland’s specified range
- Wrong Single/Double Compression configuration
- Cable construction was not considered
- Wrong enclosure entry/thread
- Nominal gland size was confused with cable OD
Check the cable datasheet and Dowells selection data before changing the gland size.
12. Can the same 63mm gland be used for different cables?
Only when the cables fall within the applicable manufacturer’s specified dimensional range and meet the required construction and installation conditions. Do not assume that two cables with the same conductor size require the same gland.
13. Where can I buy Dowells 63mm cable glands in India?
Thunderbolt Electromech India Pvt. Ltd. supplies industrial electrical products and cable glands. For a quotation, provide the Dowells 63mm size, Single/Double Compression requirement, cable OD, cable construction and quantity.
