BLOC-O-LIFT Gas Springs provide force to a system, yet are self-locking for infinite, precise positioning. BLOC-O-LIFT gas springs are oil- or gasfilled to achieve rigid or elastic locking and offer a controlled rate of travel. Compact size, dependability and cost-effectiveness make the BLOC-OLIFT ideal for all types of counterbalance applications where positioning is a requirement. Please call for a brochure of the sizes and poundages available.
