Incorporated in 2007, 10-SPEC Atlantic Building Specialties in Point Loma's Sunset Cliffs corridor supplies and installs Division 10 commercial interior components from its Cañon Street office. The scope covers restroom partition systems in phenolic, solid plastic, and stainless steel—materials that general contractors like Kanna Construction & Remodeling spec into tenant-improvement and ground-up builds across San Diego. Field-measurement crews visit each job site before fabrication to verify stud spacing, ADA clearance dimensions, and door-swing geometry, reducing change orders that typically stall Division 10 punch lists. The product line extends beyond partitions to fire-protection specialties, lockers, display cases, and flagpoles—items that often ship on a different schedule than the finish trades that install them. That scheduling complexity is where 10-SPEC coordinates with finish subcontractors such as Advance Glass & Mirror to sequence deliveries around glass and mirror installations in the same restroom or lobby space. The highest-complexity orders involve multi-floor healthcare or institutional buildings requiring fire-rated access panels, ADA-compliant grab-bar blocking, and custom-color powder-coated partitions across dozens of restrooms on a single construction schedule.
