DDI Louver Damper Linkage

• DDI linkage is adjustable to permit field alignment after major maintenance.

• DDI linkage is maintenance free and durable.  Side loads caused by crank alignment errors (kinematic locking) are relieved by deflection in the connecting rods.

• Zero backlash reduces flutter tendency and assures more positive closing.

• Crank pivots are corrosion free bearing inserts on stainless steel shoulder bolts.
