Our team designs and produces specialized fabricated door and window assemblies for heavy trucks
Built specifically for the heavy doors and windows of a semi-truck, our specialized fabricated door and window assemblies include window regulators, electrical components, window glass, hardware, and manual cranks.
Our flagship products are window regulators for Class 6, 7, and 8 trucks. They are the product we first began producing in 1946. Since then we have expanded our abilities to be capable of design, production, assembly, and delivery for inner door modules of all kinds. In addition, we offer in-house performance-testing on every component, module, and assembly we manufacture.
