Disclosed is a planar exterior forming square rack pipe, which comprises a rack pipe main body, a joint coupling protrusion part, and a plane forming member, and thus the outer surfaces of the planar exterior forming square rack pipes can be simply formed as a plane without operations such as the attachment of a separate member, such that the coupling of additional objects to the outer surface of the planar exterior forming square rack pipe such as the assembly of a planar panel, the mounting of a shock absorber, the mounting of a name plate, and the fastening of angles is simplified, assembly and mounting for the coupling of the additional objects can be completely carried out, and external foreign material such as dust can be blocked, and the rigidity of the exterior of the planar exterior forming square rack pipe can be reinforced relatively more than that of a conventional rack pipe having a curved shape so as to allow the rack pipe to be used as a pillar for supporting heavy materials or receiving a heavy load, thereby enabling stable support.

A post coupler has one or more positive post stops therein limiting extension of an end of a post section in or over the coupler beyond the stop. The stops may be freely extended tabs or stop embossments from or in the coupler flanges. Outside wrap, inside wrap and hidden post couplers are disclosed, as well as assembly methods.

A retail display unit includes a wall having a panel supported by first and second horizontal frame members and first and second vertical frame members. At least one slider is attached to the first vertical frame member and includes a channel. At least one mounting bracket assembly is slidably coupled to the at least one slider and includes at least one ear positioned in the channel of the at least one slider, at least one flange configured to mount to an upright of another retail display unit and a securing mechanism for tightening the at least one bracket assembly to the upright. The at least one ear is configured to slidably move inside the channel and thereby slidably adjust the position of the bracket assembly along a length of the at least one slider.

A post coupler has one or more positive post stops therein limiting extension of an end of a post section in or over the coupler beyond the stop. The stops may be freely extended tabs or stop embossments from or in the coupler flanges. Outside wrap, inside wrap and hidden post couplers are disclosed, as well as assembly methods.

A weapon mounting system including a base and an upright for supporting a weapon holder. The weapon holder is supported for sliding movement along the upright.

A method and apparatus are disclosed for providing a coat rack, a shoe rack and a tool rack all modified from a staple commodity of construction commerce such as polyvinylchloride piping. Methods for modifying this construction material for a specific use as one of the various types of racks is disclosed along with the tools and techniques necessary for such modifications.

The present invention relates to a bar section for a portable modular bar comprising a frame portion having spaced upper and lower rails connected by opposing side rails, the upper rail comprising a slot extending into its upper surface, and a display panel portion comprising a hook configured to cooperate with the slot in the frame portion in order to mount the display panel portion on the frame portion. The present invention also relates to a modular bar comprising a front bar section, a side bar section hingedly connected to a side rails of the front bar section, and a cover section having a peripheral lip configured to fit around the upper part of the front and side bar sections.
