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 black entrance gate in Miami Beach, combining elegant design with robust security.
In South of Fifth (SoFi), a sophisticated residential area in Miami Beach, we installed Ninja Deterrent™ Gothic continuously over the entrance gate of a condominium.
In an environment characterized by the contrast between white stucco walls and a black gate with a black frame, the aim was simple: To make it difficult to climb over. While maintaining the aesthetic appeal of the architecture.
Many security upgrades in the area prioritize security and have an overly aggressive appearance. This property sought the opposite, aiming to increase perimeter security while preserving the gate's clean, minimalist look.
That's where Ninja Deterrent's Gothic series comes in. Its silhouette is sharp yet understated. It has presence when approached but is barely noticeable from a distance. Straight lines, matte black hardware, clean frames seamlessly integrate into the existing design aesthetic.
Black entrance gate surrounded by white stucco walls. Gothic anti-climb spikes are arranged in a straight line on the top.
Gothic is installed along the entire length of the top edge of the gate, eliminating starting points for gripping or stepping, while maintaining a minimalist look.
This gate originally had a strong modern presence created by straight lines and a black frame. By adding our Gothic Series, a quiet but decisive layer of security is added.
Seen from the street, it's a well-organized detail. Up close, the message is clear: You can't climb over
Close-up from an angle: Gothic's "crown" aligns with the frame line, fitting in architecturally. Understated from afar, clear up close.
