Abstract: A fastening arrangement and method are provided for coupling a pair of frame members together. The fastening arrangement includes an insert receivable in a slot of one of the frame members. A fastener couples the insert with a receiver, such as a nut or a second insert, receivable in the other of the frame members. The insert includes a notch or similar indicator for indicating the appropriate depth to which the insert is to be driven relative to one of the frame members. The insert includes a threaded portion. The threads of the threaded portion are configured to be embedded into one of the frame members as the insert is driven relative to one of the frame members to secure the insert thereto.

Abstract: A corner piece is provided for interconnecting frame members. The corner piece includes a first plate member defining an inner face, an opposite outer face, a first side face, an opposite second side face, and an end face. The first plate member including a bolt-receiving bore therethrough. A second plate member defines an inner face contiguous with the inner face of the first plate member, an outer face, a first side face, an opposite second side face, and an end face. The second plate member includes a bolt-receiving bore extending between the inner face and the outer face thereof along a first axis generally parallel to the inner face of the first plate member.

Abstract: A presser assembly is provided in which a presser plate or presser board mounting adapter is clamped to a lower end of a presser stem. A rail having a lower channel and an upper channel is provided for clamping the presser plate or presser board mounting adapter to the stem, and more particularly, a presser foot coupled to the lower end of the stem. The present invention allows the presser plate or the presser board mounting adapter to be mounted to the stem without the use of tools or fasteners.
