Unistrut Concrete Inserts

If you are regular Tech Talk blog visitor, you’ve probably read some of our articles covering the various anchors used to attach Unistrut channel to concrete ceilings, walls, and floors.

Concrete anchors make their way into many Unistrut installations, but there are times when you need a section of channel cast-in-place too.  In these cases, our custom and stock size concrete inserts offer an ideal solution.

Browsing through the Unistrut Engineering Catalog or our website, you’ll see a wide range of continuous slot and spot inserts designed for use with pre-cast, pre-stressed, or poured-in-place concrete applications.  Continuous slot inserts allow for connection points along the entire length of your strut while our spot inserts fit the bill when you have a shorter, pre-defined connection area in mind.Consult the table below and click the appropriate part number to view more information on Unistrut Concrete Inserts
