Hi there,
I’d like to install this clothesline into a brick wall. The bricks are hollow and look almost a bit brittle:

The product manual specifies to use 8mm masonry wall anchors. Do they mean something like the 8mm Ramset Ankascrew? What length? Or is it better to use some sort of wall plugs?
Alternatively, given the bricks are hollow, would it be a good idea to install this into the mortar between the bricks (even though the manual says not to do that)? Spacing of the hole on the bracket would allow that.
Thanks,
Tom
