SALSBURY 4C HORIZONTAL
The architectural requirement for all high-density biotech developments in Oyster Point and major commercial renovations in the SSF Business Park. These recessed units are engineered to meet the ultra-high volume parcel demands of pharmaceutical and tech campuses. Every bank is calculated to meet the strict 1:5 parcel locker ratio required for modern South SF complexes. Non-compliant installations face rejection at the Chestnut Avenue Main Post Office; we provide the certified technical oversight to ensure first-pass approval for life-science real estate portfolios.

STANDARD CBU PEDESTALS
Designed for South San Francisco industrial parks and residential clusters requiring centralized outdoor delivery. Our units feature marine-grade powder coating to withstand the salt-air environment of the SSF Bayfront and Sign Hill slopes. Each installation includes mandatory seismic-stabilized concrete pads and 5-inch minimum structural anchoring required for Lindenville industrial zones. We manage the full project scope to ensure your street-side pedestal systems are legally documented with the SSF Building Division.

RESIDENTIAL FORT KNOX
The 'Tank' of SSF curbside security, constructed from 1/4" cold-rolled steel plate. These units are specifically requested for high-security estates in Sign Hill and the Hillside District to stop mail fishing and pry-bar theft. A Fort Knox unit is built to withstand direct sledgehammer impact and features a vault-grade steel hinge and anti-pry door reinforcement. These units provide 400% more physical protection than standard residential boxes and are architecturally approved for South San Francisco's residential corridors.

COMMERCIAL FORT KNOX
Maximum-security collection systems for high-risk industrial zones and commercial hubs near Industrial Way. These 400lb vaults are the industry standard for securing vital business paper trails against extreme burglary attempts. Featuring internal baffle-entry technology designed to eliminate mail fishing common in high-density areas. Built from precision 1/4" cold-rolled industrial steel, these units offer an impenetrable barrier for high-volume commercial mail and private courier drops. We specialize in the reinforced structural seismic base installation required for these ultra-heavy security units.

MAILBOX REPAIR & LOCKSMITHING
South San Francisco's primary response team for commercial mailbox repair and technical locksmithing. We specialize in resolving a broken master lock, performing precision drill-outs for lost commercial mailbox keys, and restoring unit integrity after a break-in or vandalism attempt. While federal law dictates that only the Postmaster can perform a USPS arrow lock replacement, we provide the essential structural restoration and master door alignment required for the USPS to resume delivery. Our team maintains a localized inventory of Salsbury and Florence components to ensure 24-hour turnaround for apartment mailbox lock replacement and tenant rekeying.
