US Patent 7739807 Siding gauge device for staple gun

A gauge device for use with a staple gun serves to align the staple gun relative to building siding to dispense a two prong staple from a head of the staple gun into one of a plurality of fastener apertures in siding members of the building siding. The gauge device comprises a pair of flanges arranged to depend from laterally opposed sides of the head of the staple gun at a location such that abutment of one of the flanges below a lock edge channel of a siding member locates one prong of the two prong staple to be in alignment with one of the fastener apertures and locates the other prong of the two prong staple above the top free edge of a nailing flange of the siding member.
