CARROLL nickel plated brass 'BULLET' cable glands are tested (and certified) to IP68, in accordance with AS1939-1990. This rigid rating is your guarantee of superior grip, strain relief, sealing and protection of your electrical installations against the ingress of dust, moisture and submersion. Our unique 'BULLET' design speeds installation and reduces inventory through extended cable diameter range, and eliminating the need to disassemble the gland before installation. Note: Metal glands are not supplied standard with locknuts. These are ordered separately.
