Ive got a brilliant one for phone/cctv cable that I, ahem, emancipated from it's previous cruel masters.... It's great but as I said I wouldnt use it on low voltage even on singles which it would fit, the insulation on the staples just isn't good enough These thugh, if it has the power of the one I have it would be well worth it. Not exactly what I was looking for to start with but still looking good.
lenny, liking the look of those non conductives, the price as well. Not sure how they would stand up to mortar, but theres only one way to find out....
EDIT: Just looked at the UTAC one more closely and it only does up to 1.5mm, whereas the arrow one only does 2.5 and 6mm. Hmm, could be a pain to get both. I wonder if the UTAC staples would fit my current stapler
