Inward swinging gate:
You need to determine whether to attach the rear
mounting bracket directly to the post (or wall) or to
notch the post and install a recessed liner. Large pillars
require a recessed liner to house the rear mounting
bracket and part of the operator so that the pillar will
not interfere with the swing of the gate when it is fully
opened.
To determine whether you need a recessed liner,
measure the distances B and D (shown in Fig. 9) on your
gate. If your measure of B or D is greater than the
dimensions shown for your operator in Figure 9, notch
the post and construct a recessed liner for the post
mounting bracket (see Figure 7). The recessed liner
should be constructed of 3/16 or 1/4 in. steel with a
minimum interior height of 8in. (252.4 cm) so as to
allow you to meet the required dimensions shown in
Figure 9. Make sure the recessed liner is securely
embedded in the post (or wall).
There are two parts to the rear mounting bracket. The
horizontal bracket attaches to the operator, and the
slotted vertical plate attaches to the gate post. Weld the
two parts together and bolt the assembly to the gate
post of column. Note, though, that use of the vertical
rear mounting plate is optional.
Once you have positioned the rear mounting bracket,
attach the bracket to the post (or wall or recessed liner),
making sure the dimensions on your gate system match
those shown in Figure 9.
Outward swinging gate:
If you are installing the 415 Operator to swing the gate
outward, construct a steel elbow of sufficient size to
attach to the gate pillar and rear mounting bracket (see
Figure 10 for elbow dimensions).

Disengage the operator’s manual release (see figure 2).
You should be able to lengthen or shorten the cylinder
by pulling or pushing the cylinder. Lengthen or shorten
the operator to the required distance for your gate
installation:
Inward swinging
: Lengthen the piston rod until
the appropriate limit led goes out on the
control panel.
Outward swinging
: Shorten the piston rod until
the appropriate limit led goes out on the
control panel.
With the gate in the fully closed position, temporarily
clamp the front mounting bracket (previously attached
to the operator) to the gate leaf and insure that the
cylinder is level.
Remove the operator from the front mounting bracket
for welding.
If the cylinder has not been extended beyond its limit
switch attached to front mounting bracket, then with
the operator detached from the front mounting bracket,
permanently attach (weld) the front mounting bracket to
the gate leaf (see Figure 8).
Once the front mounting bracket is welded in place, you
can reattach the operator to the bracket.
