Doorway Preparation
1.1 Inspect. If carton or doors are damaged from shipping (bent shaft, etc.),
note of carrier delivery ticket and contact factory if needed.
1.2 Make sure door opening is square and plumb (measure diagonals).
This is important for proper operation and appearance of doors.
1.3 Match size of door opening to size on packing slip.
1.4 Mark center plumb line on jamb (Fig. 1). This line will
be used to locate the mounting holes.
1.5 Install Jambguards. Center Jambguards using vertical centerline.
Use Jambguards as template to mark and drill 3/8” X 2” deep holes into concrete floor.
Use 3/8” X 2” masonry anchors to secure Jambguards (provided by others).
1.6 Use the dimensions on Figures 5 & 6 to locate
the 4 mounting holes for the top cam bearing (Fig. 5)
and the 2 mounting holes for the bottom bearing (Fig. 6).
Mark these locations with a center punch.
1.7 At each mounting hole location drill a 5/16” hole
and tap for 3/8” 16 bolts.
1.8 If jambs are wood or hollow metal over wood, fasten using
1 1/2” wood lags (provided by others). Hollow metal frames without wood
roughblocks should have 1/4” steel reinforcements welded over mounting locations.

Top pilot holes for V-Cam
