FIELD: construction engineering. SUBSTANCE: this supporting spacer of large area allows for separating some articles from stack that is by displacing or turning of given supporting spacer relative to one or several supporting spacers located above it by simple method. Supporting spacer of large area has hole for inserting fastening member. On surface of supporting spacer directed towards fastening there are members which increase cohesion with plate to be fastened and/or strip of roofing material to be fastened.
