Patent ID: 7396004

Claim:
In a bar clamp extension for extending the length of a bar clamp assembly which includes a primary bar having a distal end and a proximal end, a releasably mounted jaw on the distal end of the primary bar, a relatively moveable jaw attached to the proximal end section of the primary bar, the improvement comprising: an extension bar having a proximal end and a distal end; and coupling means at the proximal end of the extension bar for releasably attaching the extension bar to the distal end of the primary bar in longitudinal alignment, the coupling means including a cylindrical body with a proximal end configured to receive the end of the primary bar and a distal end fixed to the proximal end of the extension bar, and a hollow sleeve having a proximal end and a distal end and configured to be slideably received over the cylindrical body surrounding the respective ends of the primary bar and the extension bar received by the body.
