spruce that looks like a wall standoff and for corners of walls probly not idel for on roof tiles ,if u look on e.bay microlite standoffs come up cheep i got mine for £20 ide never pay £160 tho as i dont use them that often
I agree. I initially bought it as a standoff with wheels. I liked the V in the support rung for corners although its less stable using it this way in practice.
We never had an issue when using it against walls.
The microlite is a much better product. By the photos it has two stay bars in the form of a V. So no matter how you use it its guaranteed to stay secure. I can't see exactly how to fits onto both ladder bars.
Ours has only 1 stay/support bracket so is inclined to tilt when on a sloping roof surface. If we turn it upside down its fine. I feel totally safe using it that way.
In hindsight it wasn't a very good purchase, but that's the way it is. It gets used upside down once every 3 months, so
