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.
Classic hook-type anti-climb spikes protecting the side fence of a blue Victorian residence near Buena Vista Park.
Victorian Side Fence | Buena Vista | San Francisco
Vivid blue Victorian-style residence near Buena Vista Park needed to secure the narrow side passage between the house and the neighboring brick wall building, a classic blind spot for intruders in San Francisco’s dense residential blocks.
Securing the Blind Spot
The gap between the two buildings is the most vulnerable route for break-ins. We installed our Classic series hook-type spikes along the full length of the metal fence. Topping the wooden gate, closing the route without touching the historic architecture.
Respecting Victorian Character
The slim stainless profile keeps the security hardware visually subtle against the ornate trim. Preserving the character of the Victorian-style architecture, while sending a clear deterrent message.
Built for San Francisco's Fog Belt
San Francisco’s marine air is rough on steel. The SUS304 stainless construction resists corrosion season after season with no repainting or maintenance.
