Thanks Jeff. It's good to get a personal recommendation. The old design was probably the ABRU design rebranded.
Do you have to leave the ladder anattended at all? I know this sounds silly as we all used to leave our ladders unattended years ago. But a lot of our contracts stipulate that they should never be left unattended.
I was wondering if the limpets would stay on while you move the ladder. Then maybe you can adjust them once you are at the next window.
How much safer is the ladder would you say? Side slip, back slip, twisting (stability you have mentioned already)
The old one was called the stableleg.
I wouldn't recommend moving your ladder with them fitted, they will only slip down the style's saying that, if you made the fitting tight enough they probablly wouldn't slip and you could make adjustments after the ladder was in position.
Side slip I can't say about, as I never had this problem, I'm sure it will give details on there web-site?
back slip I can say about, as I had them fitted when the ladder was on some types of floors you would only normally feel safe with someone footing your ladder, but the limpet held me there.
I have not suffered any twisting when the limpet was fitted, I do feel more safer with it fitted, at least the Bu**ers can't walk off and answer a mobile phone when your up the ladder? (I had that happen to me :
)
One more plus for it, Trevor Knights crew use them.
