or hold other construction articles such as lumber building units etc in fig2 and 3 there are shown two different perspective views of the support 10 the support 10 is a solid body having a wedge shape the solid body forms a polyhedron the support 10 has a flat bottom contact surface 11 a pair of parallel identical surfaces 12 only one of which is visible extending perpendicularly from opposite sides of the contact surface 11 and three flat inclined surfaces 13 14 and 15 extending between the pair of parallel surfaces 12 the three flat surfaces 13 14 and 15 together with the bottom contact surface 11 and the pair of parallel surfaces 12 form the outer boundaries of the support 10 flat surface 14 of the support 10 is the surface where the tray 20 is positioned and secured when it is desired to use it the flat surface 14 can also support construction and roofing tools or materials when the tray is not used the support 10 is constructed from an elastomeric material which is non skid with most roof surfaces an elastomeric material which has been found to be quite effective is foam rubber foam rubber is also a lightweight material making the support 10 easily portable by a construction worker or roofer the dimensions for the support 10 may vary depending on the application required however the following dimensions for the support 10 of this.
