A chord nailing restricting device features a chord plate combined with a wooden volume structure configured for lateral attachment to the web of a wooden I-joist. The chord plate is positioned on the bottom of the volume structure and features a nail restricting hole having a diameter that corresponds to a predetermined diameter of a chord nail as defined by wooden I-joist manufacturers. The volume structure has a chord nailing access cavity in an surrounding vicinity of the nail restricting hole. Once the device is attached to the web above the bearing rest, the nail restricting hole restricts chord nailing position and nail shaft diameter to manufacturer defined limits. Two devices may be combined by a web front bridge plate for simultaneous attachment of two opposite devices along an I-joist end.
