Has/does anyone use a hand bender to bender 20mm steel conduit in the UK? I want to buy an (Ideal 74-027 3/4" Ductile Iron Conduit Bender) and when I search online all the videos demonstrating its use are from the USA or Canada, where they're using a thin wall conduit called EMT. The steel conduit I have used in the UK seems more rigid than this EMT so I'm wondering if its too hard to hand bend.

Also, is there a thinner gauge 20mm galvanised steel conduit that can be threaded in the UK that would be more conducive to a hand bender.

Thanks in advance!!!

you may do better re-asking in the 'wiring and regulations' BB - more electricians read it, be warned you may get some witty answers.
I have certainly bent 20mm tube in a bender designed for 22mm plumbing pipe, but taped up the roller to make it run tighter.

I worked with a chap from NZ who swore by and at his hand bender. He produced 22 light switch drops with a nice set exactly half way down the pipe....That was 20mm2 extruded Galvanized pipe, but then that was back in the eighties when they pumped steroids in the cornflakes..........

I remember back at college the young 16 year olds would literally swing on the conduit bender and it wouldn't
put the slightest bend on the tube oh to be 9 stone again

Bending lots of 20mm tube with a plumbers hand bender is pretty impressive

Not many 9 stone 16 year olds about these days

I've misused a 22mm plumbers hand held benders for the odd bit of conduit, but it's bloody hard work bending, cutting and threading conduit without a "proper" hilmor conduit bender - at least in any reasonable quantity

Do employers still have bonus schemes for the amount of conduit installed per day - on several large projects I reckon we buried as much as we installed


Let the wind blow you, across a big floor.
