Grip-Rite® Revolutionizes Concrete Construction Industry with PROLOK®

New Rebar + Mesh Chairs Feature Unparalleled Product Attributes

Irving, TX — Grip-Rite® has introduced PROLOK™ a new line of rebar and mesh chairs – the only products with patented locking heads. No tie wire or bar ties are required since it locks automatically, saving money and time. Three new products are available: High Chair, Tilt-Up Chair and Sandplate Base.

With millions of tons of rebar and reinforcing wire mesh sold annually, PROLOK™ provides a revolutionary solution to concrete construction. The lightweight products are stackable for multi-layer grids, reflective for low-light projects and contribute to earning LEED points. PROLOK™ Rebar + Mesh Chairs are D.O.T. approved and are suitable for a variety of construction applications including commercial and residential, parking lots and parking garages, driveways, and patios.

“There is a huge market for raising accessories, but no raising product currently comes close to PROLOK’s features and benefits” says National Sales Manager Blake Baldwin. “It was developed by asking real pros on job sites what they did and didn’t like about current high chairs and what they would like changed. As a result it secures rebar and mesh faster, easier and better.”

High Chair With its patented locking head design, the PROLOK™ High Chair saves contractors time. It raises rebar or wire mesh, tightly secures a rebar intersection without the use of tie wire or bar ties, and is stackable.



Tilt-Up Chair With over 10,000 buildings, enclosing more than 650 million square feet being constructed, tilt-up construction is one of the fastest growing construction industries in the U.S. Since all tilt up construction requires rebar or wire mesh, the PROLOK™ Tilt-Up Chair is a vital component to any project. The patented locking head design and other efficient components reduce ties and prep time by approximately 50 percent. The EZ Flow base allows concrete to flow smoothly through the panel’s reinforcing grid, while the 4-point base leaves an invisible footprint.



Sandplate Base The PROLOK™ Sandplate Base provides an additional support base for stability with all PROLOK™ High Chairs in soft and sandy applications and gives chairs a 4 in. diameter. The base will not puncture vapor barriers and ensures settling will not occur before the pour.
