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.
Modern serrated anti-climb spikes crowning the stucco walls of a Japanese-inspired city residence in San Francisco.
Japanese-Style Residence | San Francisco
This Japanese-inspired residence combines charcoal stucco walls, timber joinery and shade sails. The owner wanted perimeter security that wouldn't interfere with the architecture.
Architecture-First Security
The Modern series’ continuous serrated profile echoes the clean horizontal lines of the stucco walls, making the deterrent feel like a designed edge rather than added hardware.
Every Approach Covered
Spikes run the full perimeter — over the timber gate structure, along the wall beneath the shade sails, and above the frosted-glass side entrance — leaving no climbable section.
Low Profile, High Deterrence
At just 50mm tall, the serrated blade is nearly invisible from the street, yet unmistakable to anyone sizing up the wall.
