On Fri, 20 Jan 2006 18:52:16 +0000,it is alleged that Andy Wade
spake thusly in uk.d-i-y:

Did anyone answer Tim's original question about how to terminate PVC
conduit to a metal box? You use a fitting called a "female adaptor"
like these:

The adaptor body push fits on the end of the conduit (& can be glued if
necessary) and leaves an end with an M20 female thread. Then a 20 mm
male bush (comes with the adaptor) is pushed through a box knock-out and
screwed into the female part (if you'll pardon the expression). The
bush does restrict the i/d of the conduit a bit, but 2 x 2.5 mm^2 T&E
cables will go through OK (just).

Sadly those are only available from TLC and the like for round
conduit. It does seem to me that such a device (maybe even just
pushfit) should exist for the oval 'conduit'
