The ladders are used to make the cornice in a roof structure with two slopes. The last trusses (the ones that completely sit above the walls) are dropped the thickness of a 2x4, and the ladders, made with 2x4, are installed over those trusses and are nailed in the second truss. In this way, the cornice is much more solid than if we only let the OSB panel exceed the last truss and that we rebuild a structure below.
Assembly
Our new ladders assembly table is very ergonomic. Work is thus faster and it is less physically challenging for the worker.
