Our Custom Concrete Spacers

Custom Molding

American Spacer Technologies Inc., specializes in custom molding, we have completed many custom molds for direct customers and indirect clients and manufactured the parts. 

Bar Chairs

Bar Chairs are used to position reinforcing bars, wire mesh, post-tensioning cables, electrical conduit and other items embedded into concrete such as widely spaced light steel in slab construction.

High Chairs

These high-quality supports have been designed for maximum aggregate flow and concrete consolidation.
They will securely cradle all sizes of reinforcing.

Stack Chairs

Made of high-density polyethylene, these chairs provide excellent and long-lasting corrosion protection, both on the job-site and in concrete.

Mesh Chairs

These handy and durable chairs help ensure the integrity of remesh or cable during concrete pours.
The flexible seat attaches firmly to cables and remesh where they intersect with no need for ties — thus providing an effective, secure attachment point that won’t shift during the stress of concrete pouring.

Bolster Chairs

Plastic slab/beam bolsters are a continuous rebar support used in tilt-up and cast-in-place slab and deck construction.
They are ideal for both light and heavy-duty rebar support applications and are suitable for stainless, black and epoxy rebar.
