A position adjustable support assembly provides a support extension that is detachably attachable to a support member. The support extension is attached by an extension attachment that has a support coupler that extends along the length of the support member and has a gap opening to allow the support coupler to be snapped onto the support member. The support coupler may be cylindrical in shape and snap over the rod-shaped support member in a concentric coupling arrangement. The support member has a fin slot for retaining a plurality of fins that extend up from the outside surface of the support member. The fins are slid into a retaining slot along the inside surface of the support coupler to retain the support coupler and support extension in a rotational position with respect to the support member. The support extension can be slid along the length of the support member.

A bracket device includes a longitudinal wall, an end wall, a mounting member, a protruded lug, a blocking member and an elastic member. The end wall is connected to the longitudinal wall. The mounting member is connected to the end wall. The protruded lug is arranged on the longitudinal wall and includes a supporting section. The blocking member is movably mounted to the protruded lug, and includes a blocking part and an extension part. The extension part is configured to abut against the supporting section of the protruded lug. The elastic member is configured to provide an elastic force to the blocking member for holding the blocking part of the blocking member at a predetermined position relative to the end wall.

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 bracket device includes a bracket, a mounting member and a locking member. The bracket includes a first end part and a second end part. A space is defined between the first end part and the second end part. The mounting member is arranged adjacent to the first end part of the bracket. The mounting member has a mounting part located in the space. The locking member is arranged on the bracket and includes a locking part and an operating part. Wherein, the locking part of the locking member is held to be located at a position in the space of the bracket. The locking part of the locking member is able to be moved away from the position in response to operation of the operating part of the locking member. Wherein, the operating part of the locking member is not located in the space of the bracket.

An expandable shelf assembly includes a first half, a second half, and an internal mechanism. The first half includes a surface, a top end, and a bottom end. The second half includes a surface and an angled portion extending away from the surface of the second half. The internal mechanism includes a reinforcement bar connecting the top end and the bottom end of the first half, and a stop disposed on the reinforcement bar. The second half is slidably received within the first half such that the second half is partially encapsulated by the first half and the internal mechanism. When the first half and the second half are slid apart a predetermined distance, the stop of the internal mechanism is configured to engage with the angled portion of the second half to prevent the second half and first half from sliding apart beyond the predetermined distance.

A shelving structure may include at least four vertical posts, at least four annular spacers, and at least a shelf board, and the posts are configured to be mounted on the shelf board through the annular spacers. The shelf board has a frame and a panel, and a convex portion is formed at an inner edge of the frame. At least eight horizontal supporting boards are formed at four upper edges and four lower edges of the frame respectively. Each two adjacent supporting boards are not connected to each other, and each of four corners of the frame is bent to form a concave groove. Moreover, four arc boards are respectively assembled with the four concave grooves, and each of the arc boards has two wings configured to be welded with the convex portion of the frame to improve the structural strength of the shelving structure.

Disclosed is a frying pan holder including a frame structure including a pair of vertical frames that are spaced apart from each other and are vertically formed, and one or more horizontal frames that connect the pair of vertical frames, and a plurality of holding members, each of which includes a pair of outer holding parts, each of which has a protrusion coupled to a corresponding one of the pair of vertical frames at one end thereof and has an opposite end that is horizontally curved, and an inner holding part formed between the pair of outer holding parts, wherein the plurality of holding members are formed on one side or opposite sides of the frame structure.

An equipment rack having one or more caster bracket assemblies. The caster bracket assembly is selectively mountable on a frame of the equipment rack at multiple mounting locations. The caster bracket can define a gap between the caster bracket assembly and a brace of the equipment rack frame which may be used for ingress/egress of cables or wires. Associated methods are also disclosed.

An equipment rack, a horizontal panel assemblies for the equipment rack, and associated methods. A horizontal panel assembly can be releasably mountable on the equipment rack. A releasable latching mechanism permits the releasable mounting. The latching mechanism can include a retractable pin assembly including a retractable pin having extended and retracted positions. An opening can be provided adjacent a horizontal panel to permit ingress/egress of cables.

A cable retainer gate and associated methods. The cable retainer gate has an attachment portion for selectively and removably attaching to a cable basket. A retainer portion of the cable retainer gate is configured for retaining cables on the cable basket. The cable retainer gate is movable between open and closed positions to permit placement and removal of cables on the basket.
