Dottie 1211D 3/4" Nylon Knockout Bushing, 100-Pack

Keep cables safe and installations professional with the Dottie 1211D 3/4" Nylon Knockout Bushing. Designed for quick snap-in mounting, this knockout bushing protects wires and low-voltage cabling from rough metal edges—critical for security, surveillance, monitoring and networking systems. Made from tough black nylon, the 0.75" diameter bushing resists abrasion and chemical exposure while damping vibration to prolong cable life and reduce signal issues.

Each box contains 100 reusable bushings, giving installers a reliable, cost-effective supply for camera mounts, access control panels, server racks and junction boxes. The snug fit keeps cables neatly routed and prevents insulation damage that can lead to shorts or degraded performance. Because they’re lightweight and non-conductive, these bushings are ideal for IT and low-voltage applications where safety and cable management matter.
