What Linear is known for
Linear is a long-standing brand in security and access hardware, garage and gate operator accessories, and related AV/transmission products. The Linear name appears on access control platforms, enclosure and retrofit kits, radio and diagnostic tools, power and operator wiring harnesses, and audio/video extenders used by contractors, systems integrators and facilities teams. Many Linear access and operator product lines are distributed under Nortek Security & Control branding and are commonly stocked by security and gate-equipment resellers.

- Gate and garage operator accessories: replacement power cables, wiring harnesses and strain-relief assemblies for popular operator lines used by integrators.
- Intercoms and entry hardware: keypad and reader assemblies, retrofit mounting frames and related enclosures.
- Transmission and audio accessories: digital audio extenders and CAT-based transmission modules used in distributed audio/video installations.
- Field and diagnostics tools: RF field testers and installation meters for verifying RF environments and troubleshooting operators.

Common commercial, industrial and contractor applications
Multi-door access systems for offices and retail, gate and operator maintenance for residential and light-commercial sites, AV distribution in schools and hospitality, and retrofit installs where readers, enclosures or mounting frames are replaced are typical use cases for Linear products.
