The Viper Pro SD features the all-new Quickdraw Pro cable system for faster and easier attachment to trees. The Quickdraw system includes built-in comfort grips as well as quick-connect triggers that make cable adjustments easy. Retention pins in the Quickdraw system can be removed to add a cable lock or padlock for theft deterrence while attached to a tree. The Summit FastTrack system allows users to easily add Summit Ultimate Hooks Phone & Rifle Holder to the top frame of the stand. SummitLOKT joints are locked into place before welding to reduce stress on the welds. The RapidClimb Stirrups are designed to keep the climber’s boots securely attached to the platform for added safety while ascending or descending. DeadMetal sound dampening technology fills critical parts of the stand with expanding foam. A new one-piece wrap-around armpad fully covers the front rail and armrests for added comfort and sound dampening.
