pairs of tabs 106 may be configured to receive a beam member of any dimension the distance between adjacent tab 106 pairs corresponds to the desired distance between trusses typically this distance is approximately 12 16 or 24 inches thus the alignment guide 100 of the present invention is used to align trusses by receiving a truss between the tabs 106 in each pair of tabs one tab on each side of the truss in very close adjacency thereto in one embodiment a pre drilled aperture 108 is supplied between the tabs 106 of each pair so that a single e g double headed nail can be driven through the spacer rail 10 and into the truss this temporarily secures the channel to the truss apertures 108 provide for optimal placing and easy driving of nails alternatively nails can be driven directly through the flanges 104 under a preferred embodiment of the present invention the alignment guide 100 typically is ten feet long about 2 u215e inches wide and u215e inches high the punched tabs 104 are preferably spaced to receive 2 inch lumber such as u201c two by fours u201d or u201c two by sixes u201d from which trusses typically are constructed in one embodiment a distance of approximately 24 inches separates the tab pairs 107 alternatively the.
