Available as either UNITOP or ISO 21287, ST stopper cylinders are ideal for locking applications where safety, long life, reliability, and high static holding forces are essential.
A large-diameter, hardened, chromed stainless locking bolt provides a high lateral force load-bearing capacity for locking or stopping applications, offering extreme strength and durability.
These cylinders are available in various versions to accommodate different stopping or locking conditions.
They feature a robust design with bore sizes ranging from 20 mm to 80 mm, and users can choose between single-acting and double-acting configurations.
