Glossary Of Terms
BLANK POST
- A blank post has no holes routed for
rails from the sections to slide into it. This post is
used normally as a gate latch post. The gate may not have
any sections attached on one side or both sides so
therefore no sections need to connect to the post. No
holes in the posts are necessary for rails. Also a blank
post can be ordered to allow custom cutting of holes for
certain applications.
CANTILEVER GATE
- A sliding gate that uses a
counter-balance that rides in or between or on rollers to
hold the gate off the ground. No portion of the gate
touches the ground and it does not utilize wheels or
rollers that touch the ground. The cost of a cantilever
gate can easily surpass 150% of a swing gate. Since no
portion of this gate touches the ground, it can be used
anywhere the grade is reasonably level. There are two
common tracking methods used for these gates. One
consists of 4 rollers, two at the top above the gate
frame and two at the bottom, below the gate frame. These
rollers are mounted to a minimum of two counter-balance
posts. The upper and lower horizontal gate frames ride
between the sets of rollers, so the gate frame actually
serves as the track. The other type of roller system uses
a special channel built-in to the top of the gate frame.
Two or more trolleys are then mounted to the
counter-balance posts and these trolleys ride inside the
channel. No bottom track is required, only guides to keep
the bottom of the gate riding true. The 4 roller variety
is cheaper than the trolley system, but the trolley
system is far superior and safer, since the rollers are
not exposed for fingers. Also the later has less
interference from weather, since they are covered within
the inverted channel. The trolley system also looks a lot
better since the trolleys are hidden. The 4 roller system
is not very attractive on residential gates. Roller
guards are necessary additions to the 4-roller system to
avoid injury.
CORNER POST
- This post forms a corner in a fence
layout where two sections meet. The corner can be a 90
degree angle or anything close to that. There is a point
at which the angle will exceed the practical use of a
corner post and a line post should be used instead. the
approximate angle is 135 degrees where 180 degrees is a
straight line. A corner post has two sides routed for
rails. The routed sides are adjacent to each other.
Routed holes allow the sections of fence to connect to
the post.
DOUBLE SWING GATE: aliases DOUBLE DRIVE: DRIVEWAY GATE
- A hinged gate with two
leaves. Many single swing gates are not possible at great
widths, so a second leaf is used. Maximum widths depend
on fence style.
END POST
- An end post terminates a line of
fence. Only one side of the post has routed holes for one
section to connect to it. A gate post is also an end
post, because the sections end there and the gate starts.
Gates to not have to slide into routed post holes. Some
styles of fence also require that a gate post have a
heavier wall to support the gate. The wall thickness is
the width of the post wall in the case of a hollow post.
GRADE; FENCE VS GROUND
- The earth's vertical height. This is
also the bottom of a fence, where it meets the earth. A
level grade is exactly that. The earth at that location
is level. A slope is a declining grade. In a
LINE of fence, the GRADE can be different and changing
along its length, requiring special considerations at the
point of drastic grade changes. The earth's grade and the
fence grade do not have to be identical. If they are
different, the fence will have a space under it or
require burying into the soil.
LINE of fence
- Any straight line of fence unbroken by
gates or openings in the line. The line must be straight
on its length as well as its vertical grade within the
"raking" ability of that style. Some styles of
fence permit "raking" while others do not. How
much a style will rake, depends on the style. If the LINE
of fence exceeds the raking limitation, the line must
terminate at that point of change. An example: If you
look down the line from the end across the top of the
fence, it appears to be perfectly straight, left and
right, along its length, but the fence rises and lowers
vertically to compensate for ground grade changes, that
vertical change might require a termination and end that
LINE of fence. In this example, the fence could be
perfectly straight both horizontally as well as
vertically for the first 50'. At that point there is a
slope that declines 1' over every 6'. That point of
vertical direction change might require a terminal post,
because the fence changed direction. If the raking
ability of the fence is less than 12" over 72",
a terminal is required and the LINE of fence is 50' for
the first portion of the fence. See stair-stepping for how to handle that.
LINE POST
- An intermediate post in a LINE of
fence. These posts are all the posts between the terminals.
In most cases, a section of fence does not include a line
post for pricing purposes.
OVERHEAD SLIDE GATE
- A gate that hangs from an overhead
track, usually an I-beam. The trolleys that ride on the
track have two wheels that sandwich the beam so they will
not come off the track. No part of the gate touches the
ground. The bottom is kept inline with guides attached to
the posts.
RAKING; alias RACKING
- The installation of fence sections
that allows the top and bottom of the fence to follow the
grade. To rake a section requires tipping it out of
square so it is a parallelogram without any right-angled
corners. It allows pickets to be vertical and the posts
to be plumb, but the top and bottom rail will not be
level. This is the easiest fence installation, but the
sections must allow raking and some styles either limit
raking or have no ability to rake at all. Advantages of
raking as opposed to stair stepping are ease of
installation, a more natural look following ground
contours and less space under the fence. To get a quick,
novice evaluation of a styles ability to rake, use this
as a guide. Fence styles with spaces between pickets will
rake more than solid styles. Fences installed without
using prefabricated fence sections can be installed to
grade more easily. Fences with large square surfaces,
such as those with lattice panel tops, are nearly
impossible to rake, without major surgery, and are not
practical to rake.
ROLLING GATE
- A sliding gate that uses a
leading front roller or wheel to hold the gate latch-end
off the ground and the rear of the gate is supported by
wheels or rollers off the ground by mounting on posts,
columns or walls. This gate will cost more than a swing
gate, but less than a cantilever gate. Since a leading
wheel or roller is used, the ground must be level and
firm, as in an asphalt or a concrete surface. Not popular
in ice and snow climates for that reason.
SECTION of fence
- The fence between two posts. Sections
can consist of horizontal rails and vertical pickets, in
the case of wood or vinyl fence. With wire fence, section
simply implies that portion of the fence between any two
posts.
SINGLE SWING GATE: aliases WALK GATE: MAN GATE
- A gate with one leaf. For our purposes
implies a hinged gate as opposed to a sliding gate.
SLIDING GATE
- Too ambiguous. Could be any
of the ones mentioned elsewhere here. Listed here because
so many people use the term.
STAIR
STEPPING
- The installation of a section of fence
where the sections are near level, but the adjacent
section is installed higher or lower than the first, so
that the top of the fence appears like stair steps. Each
section can stair step a different amount than the
others, as a declining grade is negotiated. This is in
contrast to a line of fence that is "raked", so
that each section is even with the last, but the sections
are installed out of square leaving the posts and pickets
vertical.
TERMINAL
- A post that ends or starts a LINE of
fence. Examples: Corner post, end post, stair-step post,
or gate post. In some cases as in chain link fences, a
terminal may be required to break a line into segments
less than 500' because the chain link can not be
stretched in one single piece over a longer distance. Stretch
post is a common term to use in this case, which is a
terminal post also.
V-GROOVE ROLLING GATE
- A rolling gate that uses
angle iron as a track mounted in the driveway. The angle
iron is faced with the corner straight-up and a V-grooved
leading roller rides on the track. Not popular in severe
winter climates due to fouling of the track and wheel.
There are other types of gates
for special purpose applications, but these are the most common.
