The Keystone Blank Insert Pass-Through, 12-Pack is a structured cabling accessory designed to provide clean and organized cable routing through keystone-compatible wall plates, patch panels, and mounting systems. Unlike a standard blank insert, the pass-through design allows cables to be routed directly through the keystone opening while maintaining a professional finished appearance and helping protect cable edges from abrasion. This makes it particularly useful for installations involving custom cabling, low-voltage wiring, audio/video connections, surveillance systems, access control equipment, and other applications where terminated keystone jacks are not required. Constructed from flame-retardant polycarbonate material, the inserts offer durability, safety, and long-term reliability in both commercial and residential environments. The 12-pack configuration provides a convenient solution for new installations, upgrades, and cable management projects where neat cable routing and infrastructure organization are priorities.
