The VAG5PSE Positive Stop is a genuine OEM collar designed to cap and stop movement on the lead-screw shaft of the Viking G-5® swing-gate operator. Positioned after setting limit switches, it provides a precise physical stop—preventing overtravel, protecting internal components, and ensuring consistent gate operation. Manufactured to Viking Access Systems’ standards, it’s vital for achieving optimal alignment and safeguarding against wear.
