Who fitted and still use these ( zb)s? 
I always had one on the e series erf and the ec because the steering was so easy . I was doing a lot of rdc work and i found them easy for backing on the docks . never bothered on the fodens , the steering was too heavy so there was no advantage . Bit like marmite , love em or hate em . dave
A couple of our lads fitted them to their Foden eightleggers but whenever I had to drive them I took the blooming things off. I got cracked across the wrist far too many times!

Steering knobs - suicide knobs - invalid knobs - thumb breakers. I hated them with a vengeance and removed them from any lorry I drove for more than one day. You’ll find endless threads on the UK drivers forum doing this subject to death - one went on for several pages. There were very few drivers who defended them, some of whom only appreciated them for manoeuvring in yards. Robert

Good point, Larry. They were invaluable on a forklift truck! Robert
Also on farm tractors, where the combination of power steering and wet ground meant you could spin a plough around with no effort at all. I never fancied trying one on a lorry, though.

Well ROF, I did a trip in a Scania artic for a mate of mine some years ago and it had one of the Knobs fitted, Well I found it was easier to use it because it got up the old boiler suit sleave if you didn’t,
s These were OK for fork lifts tractors and the likes of, But I do see a lot of young drivers in HGVs with them fitted, So I surpose that’s progress, ?,Regards Larry.
I think I read a previous post stated they were illegal on public roads,and had to removed when the vehicle was undergoing its annual test?
