ProChair
Designed for both strength and stability, our PROCHAIR® line delivers value and performance for the reinforced concrete professional. With 1/2" cover height increments, chair selection is simple and our industry-leading stack efficiency reduces costs. Better stacking means the chairs are less costly to store, less costly to ship and less costly to place in the field. Our PROCHAIR® products straddle lower mats, carry heavy loads, are easy to tie, and have a minimal footprint for tilt-up and architectural applications, while protecting costly form work.

ProTilt Chair
Our ProTilt Chair® ranges in size from 3/4" to 3", in quarter inch increments. Each size of the ProTIit Chair® has two cover heights to reduce potential inventory storage requirements. The ProTilt Chair® has an extra wide footprint which contributes to a more sturdy and heavy duty chair that stays in place better than lighter weight alternatives. The added support directly underneath the cradle provides for additional strength. The footprint borrows elements from our slab bolster providing a best case scenario for use on form­work, mud slabs, and tilt-slab applications.
