PATHWAY MODULE INSTALLATION
Assembling Pathway Modules: Pathway Module (EZD444MBS or EZD444MBS2) includes four (4) Series 44+
EZ-Path Pathways along with right and left hanger brackets with nuts and bolts. Hook and eye attachment is used to
join all pathways into a single bank. Install hanger brackets on both ends of the pathway bank (Fig 10).
Insert Pathway Module (Fig. 11) through grid slot and suspend by placing hanger brackets on side rails. Install
and loosely tighten bolts and nuts (1/4 -20 x 1/2” provided). Install all pathway modules at this time using same
procedure.
NOTE: For single slot grid frame (EZDG444S or EZDG444S2) it is necessary to loosen the mitered frame corner
bolts to allow pathway module to be inserted. After inserting module, install and tighten hanger bracket bolts
completely and then re-tighten bolts in frame corners.
Install Spacer Bar Assembly: In multi-slot grid frames, a spacer bar is used to separate pathway slots. After all
pathway modules are in place, install spacer bar(s) (Fig 12) by aligning with notches in side rails located between
pathway modules. Press down until top of spacer bar is flush with side rails.
Place spacer strap gasket in place over spacer bar. Install spacer strap over gasketed spacer bar, pressing strap
down tightly against gasket. Install clamping bolts at each end and tighten to clamp spacer bar in place. Tighten
pathway module bracket bolts (1/4 -20 x 1-1/2” provided).
Installing Firestop Filler Panels: Panels are used to seal any unused slots. If spacer bar(s) has been previously
installed, remove spacer strap and gasket. Place panel over slot with sheet metal side facing up (Fig 13). Align
edges of panel with frame rails and position to half-overlap spacer bar.
Holding panel securely in place with edges aligned, install panel clips (provided) at panel ends by pressing over
lip of panel and frame flange (Fig 14). Drive clip on completely. Install clip at opposite end. Use two panel clips to
secure long panel edge to grid frame. Replace spacer bar gasket and spacer bar strap (Fig 15) to secure panel
edges where they overlap spacer bar. Reinstall and tighten spacer bar clamping bolts (Fig 16).
