Where desired, it may be beneficial tocaulk or tape the backside of the vertical joints to preventlight Position the splice plate (AX4 SPLICEB) so that it is roughly centered on the joint between Tighten the four setscrews to secure the splice to the trim .

Framing screws (#6 x 7/16" or 1/2" lg.) are typical. Special conditions such as open cell installations may dictate the use of alternatemethods of attachment.

Suspend the system using minimum 12 gage steelwire spaced no more than four feet on center alongthe mains.

9 Additional wires may be required withineight inches of the cut ends of all grid componentsin areas where severe seismic activity is Brace and square the suspension Although not absolutely necessary, bracing willgreatly increase the speed and accuracy ofcompleting the remainder of the installation, and ishighly The grid system can be braced diagonally to thestructure above using either splayed wires, or rigidbracing members such as angles or cold rolledchannels. In either case, install bracing in the planeof both main beams, and cross Squaring can be accomplished by temporarilyclamping a rigid member (main beam or wall angle)diagonally across the topside of the grid system tomaintain 90 alignment of the mains and An alternate method is to cut scrap gridcomponents to fit diagonally into the ceilingmodule.

10 When installed in pairs, these short bracesare effective during layout and installation, and canbe reinstalled on top of the ceiling panels tomaintain alignment of the For small installations, it may be preferable toassemble, mark and cut the suspension systemcomponents on the floor, and then to suspend andbrace the grid Assemble and position the AXIOM components on topof the suspension Temporarily assemble the AXIOM componentsresting on top of the grid system. Check alignmentand clamp the components in Mark the location where the open side of the Axiomtrim rests on the grid members.
