12 Gauge Concrete Insert (Channel Style)

Unistrut's P3200 Series Concrete Insert 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).

Channel dimensions are 1 5/8" wide x 1 3/8" deep x 12 ga. thick. Embedment tabs are spaced at 8" O.C. and have an embedment depth of 2-7/8". The product may be supplied with Back Plates, End Caps and a Closure Strip to prevent concrete seepage into the channel, per the options below. 

Our P3200 Series is available in Pre-Galvanized (PG), Hot-Dip Galvanized (HG), Plain (PL), and Stainless Steel (SS).

Options:

  • "NC" Suffix - No Closure Strip, with End Caps & Back Plates
  • "WC" Suffix - With Closure Strip, End Caps & Back Plates
  • "X" Suffix - No Closure Strip, no End Caps, with Back Plates
