today me and Rick aregoing to take a look at metpro's Conlok system i'd like to think the
intro's already answered one of the questions that we've already had however, i've got a question for
you, rick how much do you weigh since starting at efixx i've put a little bit of timber on
i'm now 12 and a half stone wow so the first myth is correct the camera does add a few pounds
because rick i've got you up at about eighteen and a half starts no no definitely twelve and a half
where did these questions come from they come from a series of videos that we've made using Metpro's
conlok system in the first video we installed this conduit system behind us in the second video
we looked at the number of conductors we could install within the system in order that we could
wire it and in the third video rig yeah we had a look at the robust golf led bulkheads we did and
i will leave links to all three of those videos in the description however with you suggesting you're
up at a bulky 12 and a half stone i'm not sure i trust you at the minute so i'm going to need
to take a closer look at this piece of conduit that you were hanging from the start of the video
yeah so what we've got here is a coupler a solid 90 degree bend and another solid 90 degree bend
okay so all of these grub screws here which was one of the questions we had how much force could
be applied to them and i would like to suggest you're nearer 18 and a half stone than you are
12 and a half comfortably held on of that sort of weight didn't they so can you show me how
we connected them together yeah so for connecting them together we have a piece of conduit square it
remit and then just simply insert into the box and with an allen key we just wind that screw down
okay so that goes down there so hold it into position and that's what you were hanging on
effectively one of those little grub screws yeah if i wanted to change it we did that in one of our
videos i set you a task of doing the conduit and then i change my mind halfway through it's very
simple process because you don't have to obviously unspin it as you would with a threaded end
you could just swap out a box and replace it with another one so let's just pop in a through
box there that is a really simple process isn't it in order to do that another question we get asked
around that grub screw is all about electrical continuity so in other words we're so used to
threading a piece of conduit and spinning it into a spouted box and locking it off with a pair of
grips but now with that grub screw that we've wound down with our allen key that we proved can
withstand your weight rig have you got continuity in other words a low resistive earth path yeah so
this is where we took out our material tester and the long wandering lead and then removed
any resistance in the cable and then connected it to our earth bar so once it was in the earth
bar we needed to take that long wandering lead out into the system we started at one of our closest
points first in order to prove that we have a low resistance reading so going on to the grub screw
here of the angle box and reading the reading from my machine we can see we get a value of
naught point naught two of an o we went on to the m four screw and we repeated the process and again
we got 0.002 of an ohm as we walk into our system and come further away from the consumer unit in
other words adding more metallic conduit to it we expect that reading maybe to change let's see what
we get at our furthest point in our system again 0.02 so we have gone further away from the system
we've proven we have a low resistive reading for our continuity and that was replicated also when
we went to our socket outlet we went on to the coupler that attached that to the metal clad
socket and the back box and at all points we got exactly the same reading of 0.02 ohms clearly that
right through your testing process you've proved that the conduit system behind us has continuity
in other words a low resistive path however another question we've been asked is can i use
this system outside you can yeah you want to bring the camera in okay what you've got to show me rick
so metpro i've got you covered here with the all gal conduit system what do we mean by all galv
so if you see here there would normally be a thread which allows it to be galvanized as well
okay so the whole box is galvanized that means i can use it outside yeah there is one caveat
though where we will make the connection metro have recommended that we use ct1 sealant around
the spouts okay so all spouted areas have that sealant if it's going to be used outside and as
i look at some of the accessories we've got here on the table can you tell me any businesses or
companies that have used this conlock system yeah there's test scores bbc amazon and pure gm just to
name a few i think you've ever been to the pure gym but what i like about the system is you can
mix and match between a threaded and a con lock system we did exactly that here didn't we
we did yeah so as you see here on this coupler we've got the thread we've got the conlox system
and we use it to connect our flexicon adapter to run to our power pole so on the table in front
of us we've only got some of the accessories available in the conlok range if you check out
their website you can see a comprehensive list of all the items that they offer within the conlok
system one accessory i do want to highlight guys is the rapid saddle especially when you'd run off
made my life easier okay we're all about making your life easier at efix and that's whether you're
using your traditional or the con lock system the rapid saddle when in a horizontal plane means you
can just lift your conduit on and meant that i didn't have to stand at one end however if you're
interested in traditional conduit and threading and some of the more complicated bends i've also
a playlist i'll leave in the description they're going to help you out with that but this system
here reminds me of my time teaching and if you think you're probably going to be working in
electrical injury about 50 years surely using the conlock method of connecting your conduit system
will physically be easier on you physically easier on you whenever there's any work to be
carried out it's always me that has to do it on my own okay well that's good so that's physically
saving me if you've got a rick at work who does all the work for you leave it in the comments
below if you've got any other questions on the conlok system you'd like to leave please leave
them and we'll try and get back to as many as we can going to word with you about your attitude
