I have to make a bracket up for a Laser Link between 2 buildings, of which one is a old granite building. The mount will be made of 40mm unistrut. Can anyone recommend a decent fixing to use. This mount need to be rock steady and have no movement at all.
The job has to completed in one day from start to finish, as I am hiring a cherry picker to get up to the height required, and I must be able to get kit locally as it is getting done on Monday.
Resin anchors will take too long to set, before I can align the kit.
What about these?
I have some 8mm threaded rod I need for the other end. I cant seem to find the spit type fixings that are hammered into concrete and then the screwed rod is tightened up .
