Residential Side Gate | Outer Sunset | San Francisco

Project Overview

In a residential neighborhood near San Francisco’s Ocean Beach, Classic short stainless single-bladed Ninja Deterrent™ was installed on top of a narrow passage gate between two houses. The installation was carried out using a welded attachment method, ensuring long-term durability and stability.

What stands out in this project is the natural integration: the spikes appear as if they had been part of the original structure from the beginning, blending smoothly with the industrial-style steel mesh gate.

Design Perspective

This case demonstrates how Ninja Deterrent™ can be installed in tight urban spaces without disrupting the property’s design balance. Key points:

  • Welded installation ensures permanence and robustness.
  • Minimalist form blends into the utilitarian metalwork.
  • Psychological deterrence is achieved without excessive visual aggression.

Conclusion

The Ocean Beach residential installation of Classic short  stainless single bladed Ninja Deterrent™ shows how effective security can remain discreet and architectural. Rather than drawing attention, the spikes merge naturally into the existing gate structure—providing silent but decisive protection for the property.
