Dottie GBL300 Cable Bushing, 3" Insulated Ground Bushing with Lay in Lug

Deliver dependable grounding for security, surveillance and networking enclosures with the Dottie GBL300 3 in Insulated Ground Bushing. Designed as a cable grommet & bushing solution, this device fastens and grounds threaded rigid conduit or IMC to an enclosure, ensuring a secure electrical path for systems where continuity matters. The zinc/aluminum body provides corrosion resistance and mechanical strength, while the 3" size supports larger conduit runs common in commercial monitoring and security deployments. The integrated 90° copper/aluminum lay-in lug lets electricians attach a grounding jumper quickly to the neutral bus bar without extra hardware, reducing installation time and labor cost. Built for installers and specifiers, the GBL300 helps maintain code compliance, prevents stray currents that can interfere with sensitive surveillance and access control equipment, and prolongs system uptime. Specify the Dottie GBL300 when you need robust conduit grounding for CCTV, access control, and network infrastructure—order now or contact your distributor to include it in your next security or monitoring project.
