Seismic perimeter attachment clip for attaching a grid runner to wall molding comprising sheet metal base and slide elements, the base having a tab constructed and adapted to be secured with a screw to the wall molding and having a projection extending perpendicularly from the base, the slide being constructed and adapted to be attached to a grid runner, the base and slide providing a cam surfaceand a cam follower surface, the surfaces being mutually indexable to a home position, the cam surface being configured to raise the slide and an attached grid runner from an elevation at the home position when the slide is extended from the tab in response to longitudinal movement of the attached grid runner whereby an end of the attached grid runner is elevated above a lower flange of the wall molding as the end passes over a distal edge of the lower flange.
一种用于将格栅流道附接到墙壁模制件的地震监测仪夹头，其包括金属片基座和滑动件元件，所述基座具有被构造成且适于用螺钉固定到所述墙壁模制件的凸耳，并且具有从所述基座垂直延伸的突出部，所述滑动件被构造成且适于附接到格栅流道，所述基座和滑动件提供凸轮表面和凸轮从动件表面，所述表面可相互分度到原始位置，所述凸轮表面被配置成当所述滑动件响应于附接的格栅流道的纵向移动而从所述凸耳延伸时从所述原始位置的高度开始升高所述滑动件和所述附接的格栅流道，由此，当所述附接的格栅流道的端部越过所述墙壁模制件的下部凸缘的远端时，所述端部提升到所述下部凸缘上方。
