Vertical (or upright) – a jump that consists of poles or planks placed one directly above another with no spread, or width, to jump Oxer – two verticals close together, to make the jump wider, also called a spread Square oxer (sometimes known as Box Oxer): both top poles are of an equal height Ascending oxer (usually called a Ramped Oxer): the furthest pole is higher than the first Descending oxer (usually called an Offset Oxer): the furthest pole is lower than the closest. Descending oxers are not used in competitions and competitors are forbidden from jumping it. This is due to the fact that the horse may not be able to see the furthest pole before making the jump. Swedish oxer: the poles slant in opposite directions, so that they appear to form an "X" shape when seen head on Triple bar – is a spread fence using three elements of graduating heights Cross rail – not commonly used in sanctioned horse shows, and sometimes called a "cross-pole," two poles crossed with one end of each pole being on the ground and on jump standards so that the center is lower than the sides; used at small shows and for schooling purposes to help teach the rider how to properly aim the horse jump in the center of the fence Wall – This type of jump is usually made to resemble a brick wall, but the "bricks" are constructed of a lightweight material and fall easily when knocked. Hogsback – a type of spread fence with three rails where the tallest pole is in the center Filler – this is not a type of fence, but is a solid part below the poles, such as flower boxes or a rolltop; it also may be a gate or other filling decorative pieces Combination – usually two or three jumps in a row, with no more than two strides between each; two jumps in a row are called double combinations, and three jumps in a row are called triple combinations (if a horse refuses the second or third element in one of these combinations, they must jump the whole combination again, not just any obstacle missed) Fan: the rails on one side of the fence are spread out by standards, making the fence take the shape of a fan when viewed from above Open water: a wide ditch of water Liverpool: a ditch or large tray of water under a vertical or oxer Joker – a tricky fence comprising only a rustic (or unpainted) rail and two wings wherein the lack of filler makes it difficult for a horse to judge their proximity to the fence as well as the fence's height, making it a tricky obstacle usually found only in the upper divisions, and illegal in some competitions thumb Brush jump - a jump that has brush or faux grass on the top of it. Normally, the horse is able to see over the top of it and most of the time the horse's belly will hit the grass on top. These jumps have a cut out in the middle and brush on the side. There may be a fence or log on the bottom of the jump. The jump could be anywhere from 2–5 ft tall. The jump also may be wide, causing the horse to stretch out its legs and chest.
