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 classic brick side gate in Flushing, New York, harmonizing traditional architecture with modern security.
Security that doesn't compromise Aesthetics
This private residence in Flushing, New York features an elegant red brick wall, traditional lantern lighting, and an antique side gate nestled between two brick pillars.
The client's request was to reinforce the perimeter security without altering the welcoming characteristics of the entrance.
The solution was a clean installation of our Gothic Series atop the brick pillars. From the street, it portrays as a natural architectural detail – quiet, refined and well-balanced with the gate. At the same time, it decisively eliminates "grab and climb" points at the top of the pillars.
