BACKSTORY: Slatwall (also known as slotwall) is a building material used in shopfitting for wall coverings or display fixtures. It consists of panels, usually 4 ft. by 8 ft., made with horizontal grooves that are configured to accept a variety of merchandising accessories.^[1] The panels are typically made from medium-density fiberboard (MDF), with a finish such as melamine paper pressed or laminated onto one or both sides. Grooves are then machined into the board and painted or fitted with plastic or aluminum inserts.^[2] (SOURCE: Wikipedia)

BACKSTORY: In astronomy, geography, and related sciences and contexts, a direction or plane passing by a given point is said to be vertical if it contains the local gravity direction at that point.^[1]

Conversely, a direction or plane is said to be horizontal (or leveled) if it is perpendicular to the vertical direction. In general, something that is vertical can be drawn from up to down (or down to up), such as the y-axis in the Cartesian coordinate system.

The word horizontal is derived from the Latin horizon, which derives from the Greek ὁρῐ́ζων, meaning ‘separating’ or ‘marking a boundary’.^[2] The word vertical is derived from the late Latin verticalis, which is from the same root as vertex, meaning ‘highest point’ or more literally the ‘turning point’ such as in a whirlpool.^[3]

Girard Desargues defined the vertical to be perpendicular to the horizon in his 1636 book Perspective.

In physics, engineering and construction, the direction designated as vertical is usually that along which a plumb-bob hangs. Alternatively, a spirit level that exploits the buoyancy of an air bubble and its tendency to go vertically upwards may be used to test for horizontality. A water level device may also be used to establish horizontality.

Modern rotary laser levels that can level themselves automatically are robust sophisticated instruments and work on the same fundamental principle.^[4]^[5]

In the context of a 1-dimensional orthogonal Cartesian coordinate system on a Euclidean plane, to say that a line is horizontal or vertical, an initial designation has to be made. One can start off by designating the vertical direction, usually labelled the Y direction.^[14] The horizontal direction, usually labelled the X direction,^[15] is then automatically determined. Or, one can do it the other way around, i.e., nominate the x-axis, in which case the y-axis is then automatically determined. There is no special reason to choose the horizontal over the vertical as the initial designation: the two directions are on par in this respect.

In the three-dimensional case, the situation is more complicated as now one has horizontal and vertical planes in addition to horizontal and vertical lines. Consider a point P and designate a direction through P as vertical. A plane which contains P and is normal to the designated direction is the horizontal plane at P. Any plane going through P, normal to the horizontal plane is a vertical plane at P. Through any point P, there is one and only one horizontal plane but a multiplicity of vertical planes. This is a new feature that emerges in three dimensions. The symmetry that exists in the two-dimensional case no longer holds.

The concept of a horizontal plane is thus anything but simple, although, in practice, most of these effects and variations are rather small: they are measurable and can be predicted with great accuracy, but they may not greatly affect our daily life. (SOURCE: Wikipedia)
