AD-U & RD-U Series Adaptors and Reducers provide a method of matching electrical
threadforms on Ex Equipment while maintaining certification.
Adaptors are used where the thread size of the cable gland or connection device is
larger than, or of an equivalent size to the entry thread of the enclosure.
Reducers are used to reduce the entry thread of an enclosure to accept a cable gland
or connection device with a smaller thread.
