A gate assembly is formed from a gate attached by hinges to a jamb. A pair of L-shaped brackets are attached to the outer sides of the jamb. The brackets are in turn attached to a pair of gate posts in a barrier. Bolt holes formed in the header section of the jamb receive removable eye bolts that may be used as hoisting points as the jamb is being positioned within a barrier. To maintain the shape of the jamb during such positioning, a removable sill section is included in the base of the jamb. The first upright section of the jamb defines an unobstructed internal channel bounded by input and output portals. A cable may pass though the channel and into the gate by way of the output portal. Window openings in the gate may be fitted with removable window panels containing pickets and infill material. Dual gates may be positioned within an enlarged jamb, and a removable mullion post positioned between the gates and supported by the jamb.

A portable and expandable fence system to provide a protective barrier around a campfire is disclosed. The fence system comprises a plurality of slats coupled together via a plurality of hinged connectors that allow the fire fence to be easily expanded and retracted in an accordion-like manner. In an expanded configuration, a first portion of the plurality of slats are substantially parallel to one another and a second portion of the plurality of slats are substantially parallel to one another, but positioned diagonally opposite to the first portion of slats. In a retracted configuration, the plurality of slats form a compacted cylindrically-shaped structure, wherein the plurality of slats are each relatively parallel to one another, substantially vertical in relation to the ground, and in contact with one another. In a preferred embodiment of the present invention, the system further comprises a plurality of additional safety features.
