Flex Trim

What Flex Trim does

Flex Trim is a US-based manufacturer of flexible polyurethane moulding products used to create curved architectural features such as arches, radius walls, half-rounds, elliptical applications, crown moulding, casing, base, chair rail, and jamb extensions for both interior and exterior applications. The company sells exclusively through a distribution network of building supply and millwork wholesalers and retailers (including authorized online distributors flexiblemillwork.com and trimster.com), not directly to builders or homeowners. It is operated by Carter Millwork, Inc., a second-generation family-owned private company incorporated in North Carolina and currently led by owners Alan and Greg Carter. The two manufacturing facilities are located in Lexington, NC (Flex Trim East) and Provo, UT (Flex Trim West), with the company stating it is "a consolidation of three of the oldest, largest, and most well-respected names in the flexible moulding industry": Carter Millwork, Flex Trim, and Ultra-Flex Moulding.

The company's product platform is built around four proprietary material formulations: Flex Trim® (original polymer resin blend for standard applications), ZzzzFLEX® (premium elastomer composite for demanding radius work and cold climates), Ultra-Flex (syntactic polyurethane, 40–50% lighter than alternatives, manufactured only in Utah), and Machinable S4S (an Ultra-Flex variant machinable with standard woodworking tools). The catalog encompasses more than 50,000 profiles — described as the largest selection of any moulding manufacturer in the world — with 250+ popular profiles in stock and new profiles added daily. Differentiated offerings include Xtrulinear® extended-length spooled moulding (12–500 feet continuous, eliminating joints and reducing waste), wood-grain replication molding technology that exactly replicates stain-grade profiles from customer samples, and a Lifetime Warranty against deterioration. Stock orders ship same-day before 2 p.m.; custom orders complete in approximately one week, with the company claiming the fastest custom turnaround in the industry.

The revenue model is product-based: one-time sales of flexible moulding (both stocked and custom-fabricated) priced via custom quote (no public price list, with a 4-foot minimum order), supplemented by accessories (rosettes, keystones, corner blocks) and ancillary services such as custom profile replication from customer-provided wood samples. Accessory pricing disclosed for reference ranges from roughly $5–$13 per piece depending on material and size. Marketing is conducted through the company website (which hosts profile search and dealer search tools), downloadable catalogs, social media (Facebook, Twitter, Pinterest), a blog, and the online distributor partnerships. The operating geography is the United States only; no international expansion is indicated. Revenue, headcount, and growth metrics are not publicly disclosed.

Products and services

• Flex Trim® Flexible Moulding (Original Formula) Original flexible moulding product - a unique polymer resin blend ideal for most standard flexible moulding applications. It offers excellent performance at a lower cost than ZzzzFLEX while exceeding competitors' high-end products, and bends to fit radius contours for architectural interior and exterior trim.
• Zzzz Flex® Premium Elastomer Composite Premium state-of-the-art flexible moulding - a stronger, more durable, and better-staining elastomer composite designed for the most demanding and complex radius applications, cold weather climates, small intricate patterns, and tight curvatures.
• Ultra-Flex Syntactic Polyurethane Moulding Syntactic polyurethane compound with cellular composition similar to wood, 40-50% lighter than other flexible mouldings while retaining strength and durability. Pre-primed for superior painting and staining, back sanded for better glue adhesion; manufactured only at the Provo, UT facility but available nationwide.
• Machinable S4S Ultra-Flex compound engineered to be machined with conventional woodworking machinery (shapers, routers, moulders) without dulling carbide knives, eliminating the expense of custom tooling when only small amounts of straight footage are required. Available in dimensions up to 2 inches thick, 16 inches wide, and 12 feet long.
• Xtrulinear® Extended Length Spooled Moulding Industry-first extended length flexible moulding available in continuous lengths from 12 feet up to 500 feet on spools. Eliminates need for special orders and exact measurements in advance; ideal for warehouse and job-site dispensing with virtually no waste.
• Stainable (Stain-Grade) Flexible Moulding Stain-grade flexible moulding that exactly replicates wood mouldings, corbels, and appliques regardless of wood species. Any grain pattern or species characteristic becomes part of the mold and finished product, matching oak, mahogany, pine, and other species when stained with heavy-bodied gel stain.
• Accessories (Rosettes, Keystones, Bull Nose Corner Blocks, Plinth Blocks) Flex Trim accessories available in both Flex Trim and Zzzz Flex materials, including Bull nose corner blocks, Plinth Blocks, Keystones, and Rosettes in various sizes and styles, plus Cortaels and appliques available by contact.
• Custom Moulding Fabrication (Made to Match) Custom moulding manufacturing service that creates flexible moulding to replicate any profile or item (wood moulding, decorative profiles, corbels, onlays) from customer-supplied wood samples or tracings. Custom molds are built from the wood piece and produce matching flexible moulding; tooling charges may apply depending on profile size and shape.
