Cheap plastic chairs become brittle and shatter in cold prairie weather. Worse, thick plastic blocks wet concrete and creates hidden air voids that fill with water, freezing and cracking your slab from the inside out.
Synchro chairs are bent from heavy-gauge carbon steel with a 4,850 lbs breaking force. Our thin wire allows concrete and heavy aggregate to flow perfectly around the chair, giving you a commercial-grade, freeze-thaw-resistant pour every single time.
