Corrugated Metal Side Gate | Arizona
Classic Shinobi Gaeshi black steel security spikes installed on a rustic corrugated metal side gate in Arizona, blending desert aesthetics with anti-climb protection.

Classic short dual black anti-climb spikes along a building's upper perimeter on Holmby Ave, Los Angeles — continuous, low-profile protection on an exposed ledge.
An exposed upper ledge on a building along Holmby Ave in Los Angeles offered an easy foothold for anyone attempting to climb. We secured the full run with Classic short dual (black).
Installed continuously along the parapet edge, the Classic short dual presents a dense line of pointed blades and hooks that eliminates any place to grip or rest. The black finish keeps the hardware visually quiet against the building's neutral facade.
Rather than a bulky barrier, the spikes form a thin, deliberate topline that preserves the building's lines while clearly signaling that the ledge is off-limits.
For exposed ledges and parapets, Classic short dual (black) delivers continuous, low-profile anti-climb protection that blends into the architecture.
