Patent ID: 8322700

Claim:
A system for supporting a workpiece, comprising: a first support rail having a plurality of discrete first mounting regions; a second support rail having a plurality of discrete second mounting regions, the second mounting regions and corresponding first mounting regions defining a plurality of transverse mounting positions; a receiving window between the first support rail and the second support rail; a header dimensioned to rest on the first support rail and the second support rail and to support at least a portion of a workpiece, the header comprising: a beam, a panel of actuators fixedly coupled to the beam such that free ends of the actuators are movable away from and towards the beam, and a first locking mechanism at a first end of the header and a second locking mechanism at a second end of the header opposing the first end, the first and second locking mechanisms coupleable to a pair of the first and second mounting regions to keep the header at one of the transverse mounting positions when the first and second locking mechanisms are in locked configurations, the header being movable with respect to the first support rail and the second support rail when the first locking mechanism and the second locking mechanism are in unlocked configurations; and at least one cover supported by the first support rail and the second support rail to fill substantially all of a gap between an adjacent pair of the headers.
