Because of the triangular shape of the attachment base plate, it can be secured to either of the opposed outer side edges 12 or 12' of the roof 13 as shown in Figure 1. As illustrated in Figure 4 it is secured to the outer right side edge and therefore only one of the side connecting arms, namely arm 40 is secured to the roof sheeting material 13' . In this particular instance the side connecting arm 40 is secured on top of a row of asphalt shingle, namely row 51, by roofing nails 52 disposed in the inclined slots 42.
  • These inclined slots 42 in the side connecting arms 40 and 40' are spaced apart at predetermined distance which is substantially equal to the width of a roof shingle flap 53 wherein the roofing nails 52 can be concealed by the roof shingle flaps 53' of an asphalt shingle 54 of a row of shingles secured thereabove.
  • the roofer continues to install the post support assemblies to form a barricade along the roof side edge 12 and then the shingles are installed in the usual fashion.
  • the roofer In order to disconnect the post support assembly 11 from the roof, it is merely necessary for the roofer to apply a hammer blow in the direction of arrow 55 (in the direction of the angled arm 44) on the post support assembly to cause it to be displaced from under the roofing nail heads 52 provided in the side connecting arm 40 and also provided in the extension portion 41' of the central connecting arm 41. Once this is done the attachment base plate 20 can be withdrawn from under the shingles. The roofer then merely taps over the nail heads by lifting the shingles or over the shingle with a hammer to ensure that the roofing nails 52 are further driven into the asphalt shingles as they are slightly lifted due to the thickness of the base plate.
  • FIG. 4 because the post support assembly is secured to a pitched roof it is necessary to displace the post connector 22 between the guide flanges 30 whereby to position the post 17 substantially vertically and the weight of the post, including the rails 18, maintains the post connector 22 downwardly biased on a selected pair of serrations 33.
