• Smooth Hydraulic Dampening: Engineered with internal end-travel dampening to minimize mechanical stress and vibration on mounting pins when a guard is fully extended.

• Long-Term Seal Integrity: Equipped with wear-resistant internal rod seals that resist oil contamination, chemical font solutions, and aggressive solvent washes common in pressroom environments.
