What Knickerbocker Partition Corp does

Knickerbocker Partition Corp, operating legally as Knickerbocker Bathroom Partitions, LLC, is a U.S. manufacturer of commercial bathroom partitions founded in 1951 and currently owned by Karp Associates of Melville, NY following a January 2018 asset acquisition from the Markbreiter family. The company designs and produces a complete product line organized around five mounting styles (Metropolitan floor-mounted headrail-braced, Empire ceiling-hung, New Yorker floor-mounted, Gramercy floor-to-ceiling pilaster, and Liberty total-privacy no-sightline) crossed with five material types (powder-coated baked enamel steel, Type 304 stainless steel, HDPE solid plastic under the Plastique SP brand, laminated plastic, and phenolic solid core plastic), plus urinal screens and complementary hardware. Manufacturing is conducted at the company's Melville, NY facility, with steel and stainless steel sourced approximately 90% domestically. The company also offers custom colors and brass or stainless steel hardware at additional cost, and standard powder-coated colors ship within 2-3 weeks.

The company serves commercial construction projects — schools, sports arenas, entertainment establishments, and office buildings — selling directly to building owners, architects, and contractors. Go-to-market is sales-led: a website-hosted spec generator tool funnels architects and contractors into the specification process, and orders are closed by phone (516-546-0550) and email ([email protected]), with regional sales coverage from headquarters in Melville, NY and a Dallas/Ft. Worth office in Arlington, TX. Revenue is generated through one-time project sales with quote-based pricing (not publicly disclosed). The product line carries LEED-compliance positioning through post-consumer recycled steel and zero-VOC powder coatings. The company employs 1-10 people and has not disclosed revenue, funding, or recent expansion activity; the most recent material corporate event is the 2018 sale to Karp Associates, under which Stewart Markbreiter continues as General Manager.
