These were a great solution to installing a trellis on the side of a colourbond shed. The mounting bolt for the trellis post goes through the corromount, the shed steel and then the structural upright.

The corromount was simple to drill through and fitted perfectly in the corrugation valley

Excellent to work with. You can easily drill it, cut it with a wood saw or jig saw, and you can use a wood chisel to provide clearance for existing wall Sherri g screws. I’ve used the stock sheet and made mounting blocks for my rain heads.
