BW brass internal armoured cable glands

BW brass armoured cable glands are designed for use with SWA and similar single wire armoured cables where there is a need for clamping or terminating the armour for electrical continuity and/or mechanical retention purposes.

These industrial BW brass internal armoured cable glands are small and compact. They are rated to IP54 rendering them suitable for internal applications, not recommended for installation outdoors.

Supplied complete with earth tag, locknut and shroud, also available with LSF shrouds to complement halogen free cables on request. Generally glands up to 32mm (BW-32) are supplied in packs of two and larger sizes supplied in packs of one.
