Keep installations tidy and professional with the Pass & Seymour by Legrand ACBLKM4 4-Port Keystone Frame blank inserts. Designed for commercial networking, security and surveillance environments, these magnesium-finish inserts fill unused keystone openings to provide a finished, tamper‑resistant wall‑mount appearance.

The durable magnesium finish resists wear and complements modern low-voltage hardware, while the easy-to-install connector insert lowers onsite labor time during retrofits or new deployments.
