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 anti-climb spikes topping a white vinyl side gate of an Encino residence, paired with 24-hour camera surveillance.
Side Gate | Encino | Los Angeles
A residence in Encino secured its white vinyl side gate — the service entrance tucked between the house wall and the garden fence — with black Classic series spikes, complementing the existing camera surveillance with added security measure.
Layered Deterrence
Cameras record incidents; spikes prevent them. Adding a physical barrier above the gate turns a passive monitoring point into an actively defended entry, and the black finish ties the hardware into the gate’s dark ironwork.
