  • Apparatus for aligning lapboard siding
    Patent number: 7574814
    Abstract: A pair of generally linear templates each includes one vertical edge convolved in substantially identical stepped convolutions that are each respectively conformed to support the lower end edges of an array of lapboards on the exterior of a building wall structure. Each of the templates include a set of laterally offset attachment brackets provided with spring opposed fasteners that are useful to temporarily secure the templates to the wall structure at a securement interval that is greater than the span of the lapboards, thus exposing the lapboard ends for their proper alignment as the lapboards are affixed to the wall structure.
