How to install the SeismicSeparation Joint Clip:

Step One: Install suspension systemcompletely, in a conventional manner.

Step Two: Decide upon which run(s) of MainRunners to create the seismic separation.NOTE: The Seismic Joint Clip allows for cross tees to move along the axis of the cross tees.NOTE: Divide 2500 SF by the length of therun of mains in feet. The result will be themaximum spacing, in feet, for the separation

joint. Round this result down to the nearest4' increment when mains are installed 4'on center.

Step Three: Attach two adjacent sides of eachsection of the divided ceiling to the structure.Where these sections touch the wall, theattachment may be by riveting to the wallmolding or by means of the BERC2 clip with atight screw. Sections that do not touch wallson two adjacent sides must be bracedto structure.

Step Four: Cut XL through the end detailsof cross tees inserted into the Main Runnerdesignated for the seismic separation.NOTE: This should be done one intersectionat a time or the grid system will fall apart.

Step Five: Assemble the two sides of theSeismic Joint Clip into one unit.

Step Six: Snap completed assembly overthe bulb of the Main Runner at the intersectionof the cross tees.

Step Seven: Insert a 1/4" long #10 screwthrough slot in clip, into the upper XL clipstake hole. Use vertical stamp mark below thehorizontal slot to properly position the screwwithin the clip. Install one screw from eachside of the assembled clip to hold the propershape. Do not allow screw threads to stripout the stake hole.
