GTI Composite Stack Chairs
Made in the USA

All GTI Bar Supports are 100% Made in the USA

GTI provides the strongest Composite Stack Chairs available in the market. They are made from composite material and meet or exceed the strength of comparable wire supports. 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.

The GTI line of Composite Stack Chairs contains rounded balls on the bottom of the feet so as not to damage formwork and remain invisible when concrete is exposed. Virtually no change in strength in temperatures ranging from 0ºF to 150ºF.

Primary Uses:

  • Top Layer Double Mat Support – Post-Tensioning, Rebar, or Mesh
  • Tilt-Up Concrete Wall Panels

Sizes:

  • From 12¾” to 26-½” (in ¼” increments)
