Gate Bracket and Linkage Arms
Revision E Installation 1-9
Installing the Linkage Arms
NOTE
SwingSmart operators ship with separately packaged linkage arms. The linkage arms have a
universal elbow joint and can be used on either an operator with right handing or left-handing
by simply flipping the linkage arms. The excess on the over travel stop is then sawn off to
accommodate for the top and bottom elbow joint covers.
Figure 1-9.
1. Slide the linkage tubes on the appropriate stub arms
and use the tapped holes for adjustment purposes.
Tighten the hex-head bolts to hold the arms in place.
Refer to Figure 1-10.
2. Verify the A and B dimensions on the arm linkage
tubes. For short gate applications, the linkage arms
must be cut to achieve the required lengths. See
Figure 1-9. If your operator position does not fit the
chart specs, use the Custom Gate Installation formula
to determine the proper length.

Maximum measurement for B = 47.5 inches (121cm)
Keep the elbow joint at a slight
angle to avoid hyperextension and
allow compensation for light gate
strikes without severe damage to the
gate operator.
NOTE: At secure sites, straightening the
arm lowers the chance of someone
manually pushing the gate open.
