Vectis® Spring-Assist Motion Control Technology

Weber Knapp is a motion control engineering and manufacturing partner specializing in
counterbalance solutions. Powered by proprietary Vectis® Technology, Weber Knapp
designs and manufactures heavy-duty spring-assist hinges that deliver precise, controlled
motion for demanding applications.

Vectis® hinges provide true counterbalancing, featherlight operation, and long-term
durability as a reliable alternative to gas cylinders. Engineered for safety and performance,
they are tested to exceed 100,000 cycles and operate consistently in challenging
environments.

With configurable hinge models and engineering support, Weber Knapp helps customers
improve lid, door, and access panel designs across industrial, medical, and consumer
products.

Why We Are a Leader

Vectis® Technology represents the evolution of spring-assisted motion control, combining
over a century of mechanical engineering expertise with modern, configurable design.
Unlike gas cylinders that can degrade, leak, or fail over time, Vectis spring-assist hinges
deliver consistent, repeatable performance throughout the life of the product.
Designed for demanding applications, Vectis hinges oƯer true counterbalancing,
controlled motion, and enhanced safety for lids, doors, and access panels weighing 50
pounds or more. The technology allows engineers to fine-tune movement characteristics,
including torque output and open-stop angles, to achieve a premium, eƯortless user
experience.

Vectis hinges are engineered for durability, operating reliably across a wide temperature
range and in challenging environments, including high-heat applications where gas springs

often fall short. Each hinge is tested to a minimum of 100,000 open-and-close cycles,
ensuring long-term performance and reduced maintenance.

To further support design teams, Weber Knapp oƯers the Vectis® DYO App, enabling
engineers to configure counterbalance solutions based on real-world load and geometry
requirements. This combination of configurable technology, engineering support, and
proven durability positions Weber Knapp as a leader in spring-assisted motion control.
