12 Gauge Concrete Insert (Channel Style) PS 349 Series is ideal for anchoring structures and supports to concrete. This product allows easy installation before the concrete is poured, and attachment anywhere along its length using 1-5/8" Fittings, Channel Nuts or other products. It is perfect for applications that may need to be re-configured or re-anchored. This product may be used for anchorage on ceilings, floors or walls. Being a pre-pour installation, it is ideal for applications with cracked concrete concerns and avoids the creation of Silica Dust during installation (see OSHA 29 CFR 1926.1153 and 29 CFR 1910.1053). It is also OPA approved for seismic bracing applications (reference pages 5-7 & 5-8).
