Wall | Hollywood | Los Angeles
Continuous anti-climb spike installation on a perimeter wall near W Sunset Blvd in Hollywood, Los Angeles, maintaining a clean architectural look while securing the property.
Anti-climb security spikes installed on a wooden side gate in Ashbury Heights, San Francisco, enhancing perimeter security for a residential property.
Residential Side Gate | Ashbury Heights, San Francisco
This project involved adding extra perimeter security to a wooden side gate in the residential neighborhood of San Francisco. Side gates are often hidden from the main street, making them vulnerable entry points.
To reinforce this hidden area, we installed Ninja Deterrent™ Gothic Black continuously along the top edge of the gate.
Installation Details
Gothic Dual Blade Black spikes were installed on top of the gate over the stone steps.
A stainless steel rail was placed directly atop the wooden gate, creating a discreet yet continuous line of defense.
Gothic Dual Blade Black sits subtly on top of the gate.
The installation aligns with the gate's original design, so it doesn't stand out too much from a distance, but functions as it should upon closer inspection.
Harmony with Design
The Gothic Dual Blade Black on the upper part blends in with minimal visual impact against the warm appearance created by the vertically arranged wooden panels. Without giving an overly aggressive impression, it improves security performance while maintaining a clean and modern appearance.
Summary
This project demonstrates that Ninja Deterrent™ can be effectively applied to wooden gates without compromising the design. Gothic Dual Blade Black offers a low-profile yet effective deterrent, making it a clear choice especially in urban residential areas where the balance between aesthetics and security is key.
