Abstract: A portable, extensible, and standalone security delimiter, comprising a multiplicity of portable towers with a multiplicity of links pivotally interconnected, forming a lattice structure that couple the multiplicity of portable towers with one another to enable the security delimiter expand out from a compact collapsed state to a selectably expanded operational state along a reciprocating span axis. The security delimiter further includes a latch mechanism that locks the security delimiter in the selectably expanded operational state at a desired longitudinal span, along the reciprocating span axis.
