steel trunking

grousedogtom

Hi
I need to fix steel trunking horizontal along a block wall and need to offset around a protruding vertical steel guider about 2 inch from wall, can i buy manufactured bends to achieve this? if not can someone guide me on details of making this offset myself as i haven't got much experience with steel trunking or conduit , all help appreciated.

Its not that hard, just takes a bit of practice. You will find vidoes on youtube etc that might help you. Have you got a benders?

Have you got a benders?

I think you have conduit in mind!

What size is the trunking?

can i buy manufactured bends to achieve this?

You can buy manufactured 45 degree bends, but you may find that by using them you are forced to make a set that is larger than the 50mm you require.

Always keep the sets long so that it is easy to get the lid on when it is full!

trunking will probably be 2 inch

I would have swore it said conduit

Trunking is a little harder to explain how to do without actually showing you. Its just a matter of cutting and filing in the right spots. Cutting the walls will give you the acute angles, and taking out a section of the floor will give you the obtuse angle. Is their no one that could give you a quick run down on it?

you could take a look at the site ive linked below. it will probably be unitrunk trunking that you will be using so might be of help to you.the section ive highlighted shows the internal/external bends ect.

they are based up in ballycoolan but dont deal directly with the public but they do supply many of the wholesalers around the country so there is a good chance it will be thir prouct your using.

is it possible to run a length of 2" timber each side of the steel girder and not offset the trunking?

Sets out that far look rough usually, if it was out that far its better to right angle the tube then an end box onto the trunking side.
Obviously it does`t fit coming right angle straight out from wall if only 4 inches to front edge of trunking but you turn the end box in so for example with the end box now out past front of trunking you turn the tube in its saddles 60 degrees so the end box is now neatly on the trunking with protruding tube now 30 degrees from the wall. Looks much better than big offsets straight into trunking if big ones are needed.

Trunking bending takes practice to get it right but it can be done very well in situations like the OP needs.

ya the right angle and end-box is a good job

Easier to wire as well, especially in that 2 inch trunking. Another interesting one i used to do when T-ing into an existing trunking was cut the bottom and back off the manufactured T piece and be left in effect with a flange piece, so only have to cut a single side out of the existing trunking to T into it. This left the existing trunking stronger and also just much easier to t into. Also works well for T-ing into a larger trunking with a smaller one using the modified manufactured T for the smaller trunking and cutting a suitable size piece from the larger trunking.
Worth a mention maybe.
