Kinvaro D-S 40N spring flap stay from Grass America is a lift system component designed for flap applications in work surfaces and tables. This Grass Kinvaro lift systems part uses a 40N spring to support flap motion, which helps control opening effort on lighter fronts in everyday cabinet or furniture projects. The Kinvaro D-S flap stay format works within the Grass Kinvaro lift systems family, so it slots into projects where a coordinated lift solution is needed across multiple fronts in the same run. Its 40N rating defines how much force the spring applies, which matters when matching the stay to front size and weight to keep movement consistent. The white version offers a neutral color option, which fits cleanly into lighter cabinet interiors or painted casework where visible hardware color needs to stay discreet.
This Kinvaro DS flap stay 40N white part is specified as a spring flap stay, which means it uses internal spring force to assist flap motion, shaping how the front lifts during operation. As a Grass Kinvaro lift systems component, it is intended to sit in lift or flap assemblies on work surfaces, tables, or similar casework where upward-opening fronts are used. The 40N rating is a practical sizing cue during layout, because installers can relate spring strength to front dimensions and material weight when assigning one or more stays to a run of cabinets. Its configuration as a flap stay defines that it connects between cabinet structure and front, which sets basic mounting expectations during hinge and front layout.
The Grass Kinvaro lift systems classification places this Kinvaro D-S 40N spring flap stay squarely in lift and flap-front projects for work surfaces and tables. In these jobs, the flap stay supports the moving front so it can be opened upward in a controlled arc. The 40N spring characteristic shapes how the front feels as it is raised, which can be matched to typical door sizes used in overhead storage or table flaps. As a spring flap stay, the part contributes to handling and balance of the front, so when paired with suitable hinges, the front can be positioned without feeling loose. Installers planning casework with multiple lift fronts can standardize on this 40N version for similar-sized doors, which reduces variation in how each opening behaves.
The 40N spring value on this Kinvaro DS flap stay 40N white model sets expectations for its support range, which helps installers predict whether a single stay will provide enough assistance or if multiple stays will be distributed across wider fronts. Matching spring strength to front weight affects how smoothly the flap moves, which influences user confidence in regular operation. The white color option ties into projects with white interiors or light laminates, so visible hardware remains visually consistent when the cabinet is open. Since this part sits in the Grass Kinvaro lift systems family, its defined role as a spring flap stay supports repeatable layout from job to job. Installers who become familiar with the 40N behavior can reuse that knowledge on future cabinets that call for the same opening feel.
