| GTI DOUBLE-LOCK PAVING CHAIRS™ (SERIES 217) |

 |
| |
| GTI® provides the strongest Paving Chairs available in the market. They are made from composite material and exceed the strength of comparable wire supports by up to ten times. The product size is identified on the top of the product. GTI® composite material offers continuous corrosion protection, both on the job-site and in concrete providing a great alternative to epoxy, stainless, and galvanized bar supports. |
