D C Dewey seems to be the place to get ladder spikes.
To all you that use these ladder spikes, how do you fit them?
I understand drill holes bottom sides of ladders and bolt but wondering which way round and also how much of the spike protrudes below existing ladder feet?
If anyone could show a pick would be great

Had a fall off ladder recently on decking.
have told most with flat roofs may have to miss windows over roofs.
Been getting most from small step ladder and WFP this has worked for most.
Got 1 bigger house where i think spikes might do the trick.
thanks lee
