Gate Installation:
Caution: The proper operation of the gate depends upon the correct installation of the gate
posts. Make certain that posts are plumb.
1. Gates are available in either kit form for residential and light commercial use, or as prefabbed heavy duty welded
frames for heavy commercial or industrial use. All gate openings are “nominal”, meaning a gate opening may vary
from stated width due to the location of the vertical wires. (A “4 foot” gate opening may actually measure 3’10” - 4’2”).
Openings for each gate type are always measured from inside face of gate post to inside face of gate post. Gate
openings will be affected by which type of gate is specified and what hardware is used. Each will require some
fabrication on site and any standard gate hardware that will fit the gate frames and posts can be used.
2.
For gate kits
the gate opening should be determined before setting posts. Openings are computed by adding the
actual section width plus 2¼” for gate verticals, plus allowances for hinges and latches. Jerith’s standard hardware
will add another 4” (2” for hinges, 2” for latch) to the opening. If other hardware is used, consult instructions for hinge
and latch allowances. Gate kits are assembled by inserting the stubs welded onto the 1” square gate verticals into
the top and bottom rails and fastening with two self-drilling screws at each corner (see figure 2). Use cable ties to
secure wire verticals to the uprights. Screw diagonal brace (provided) to the gate vertical near the top end of hinge
side of gate, cut to proper length, and then drill ¼” hole, cold galv, and secure with tek screw provided. Gate is
complete.
3.
Heavy duty gate frames
are comprised of 2” square uprights with 2” x 1 ½” steel angles welded in place for top and
bottom frame members and diagonals welded in place. Angle widths have been predetermined to allow for end
verticals of infill sections to abut gate uprights and to enable them to be secured with cable ties (see figure 3).
Hardware should be inspected and analyzed to determine allowances for proper gate opening width. For heavy duty
gate frames, cut sections as above, slide a rail end into rail and insert finished infill section into frame. If frames are
wider than standard section widths extra verticals will be welded into place. Secure rail ends with tech screws and
attach vertical wires to gate uprights and diagonals using strap ties.
4. Once the concrete has set around the gate posts, you may install the gates.
5. Attach hinges to the gate frame first and then the gate post. Mount one hinge near the top rail of the gate and the
other near the bottom rail to distribute the weight of the gate evenly. The gate should now swing freely.
6. For double drive gates, the drop rod is installed next. Place the drop rod high enough to ensure ground clearance of
the drop rod when the gate is opened.
7. Finally, position the latch at a convenient height (or as required by local codes) and fasten the latch onto the side of
the gate.
