When the glass enclosure containing the original manuscript of the Declaration of Independence was completely assembled, it was clamped together with "C" clamps at each corner of the case. The clamps prevented the cover plates from being pushed out of alignment with the lead strip and bracket in the soldering operation. Dr. Gordon M. Kline of NBS watches Louis Gilles and Dr. Roy Wampler of the Libbey-Owens-Ford Glass Company clamp the elements of the Declaration of Independence enclosure assembly together.
