Custom Service Hardware
Over 40 Years of Innovation and Service
Founded in 1977, Custom Service Hardware (CSH) began as a small, hands-on operation driven by problem-solving and ingenuity. What started in a Wisconsin barn with custom-made hardware components has grown into a trusted name in the home improvement industry—supporting builders, designers, and homeowners for more than four decades.
A Foundation Built on Practical Solutions
CSH was founded by Frank Rasmussen, whose early frustration sourcing reliable parts led him to begin manufacturing his own hardware. That same solution-focused mindset continues to define the company today—developing and supporting products that solve real-world installation and design challenges.
The Company Behind Trusted Brands
While many products manufactured or distributed by Custom Service Hardware are sold under individual brand names, CSH is the driving force behind several well-known and respected product lines used in homes around the world.
Notable brands developed and supported by CSH include Quiet Glide® rolling ladders and barn door hardware, InvisiDoor® hidden bookcase doors and storage solutions, and other innovative architectural hardware systems.
Manufacturing, Distribution, and Global Reach
Over the years, CSH expanded from hardware manufacturing into importing, domestic production, and large-scale distribution. With access to more than 50,000 products and strong supplier relationships, CSH supports projects ranging from residential renovations to large-scale builds.
Products developed by Custom Service Hardware are used throughout the United States, Canada, Europe, Australia, and New Zealand—demonstrating both versatility and reliability across markets.
