Abstract: One aspect of the present invention relates to a chemical-process system. The chemical-process system includes a chemical-process column and a support disposed on an interior of the chemical-process column. A tray is disposed on a top surface of the support. A bolt is disposed through the tray and a clamp is disposed below the tray. The clamp has a notch formed therein for receiving a head region of the bolt. The clamp engages a bottom surface of the tray and a bottom surface of the support. The bolt is able to angularly displace with respect to at least one of the tray and the clamp.
