1. A cable gland comprising:
an entry component sized to fit through an orifice in a surface and having a flange arranged to bear against the surface around the orifice;
a middle component in threaded engagement with the entry component; and
a back component in threaded engagement with the middle component, the cable gland defining a through bore for a cable through the entry component, the middle component and the back component;
the cable gland further comprising a sealing body which is arranged to provide a seal in at least two positions from a group comprising:
a. between the surface and the flange of the entry component;
b. between the cable and the back component;
c. between the back component and the middle component; and
d. between the middle component and the entry component,
wherein the sealing body is formed of a resilient material,
wherein the sealing body can be stretched and rolled over an outer surface at least one, two or three of the entry component, middle component and back component,
wherein the sealing body has an internal through bore through which the cable can pass and the sealing body is shaped such that the through bore for the cable can accept a range of diameters from a narrowest cable diameter to a cable diameter less than a size of the entry component, with stretching of the resilient material accommodating for varying sizes of the cable whilst still providing the seal in the at least two positions throughout the range of diameters.
