HEX BW Brass Cable Glands – Indoor Armoured Cable Glands to BS 6121, 16S to 90L

HEX BW cable glands are brass glands for armoured or braided cables. They secure the armouring and provide electrical continuity between the armour and the equipment's gland entry, and are mainly used in dry, indoor conditions such as switch rooms and control panels. Made by HEX, the brand of Brass Copper & Alloy (I) Ltd., Mumbai — an ISO 9001 company whose products are tested by CPRI (India), UL (USA), KEMA (Netherlands) and SIRIM (Malaysia).

Made to BS 6121-1:2005, the standard 4-part gland has a 3-part armour lock with a cone and lock ring for extra grip on the armour; a simpler 2-part version is also made.

Frequently asked questions

Where should BW glands be used?

On armoured or braided cables in dry, indoor conditions; for outdoor or wet areas choose a CW or E1W gland, which also seal the cable sheath.

What is the difference between the 4-part and 2-part BW gland?

The 4-part gland has a 3-part armour lock with cone and lock ring for extra grip; the 2-part uses a knurled lock that also forms a low-resistance earth clip.

What does CIEL mean?

Cast integral earth lug — the earth lug is cast into the gland. Add C to the product code to order it.

How do I pick the right size?

By the cable's diameter under the armour and its overall diameter; for example a 4-core 16 mm² SWA cable usually takes a size 25 gland. Send us the cable size and we will confirm.
