Redline® VLB-G25

The Thern Redline Series VLB-G25 vertical lead block features a 4½″ (114 mm) outer sheave diameter designed for ¼″ (6 mm) rope. It has a total working load limit of 4,000 lb (1,814 kg) and a line load limit of 2,000 lb (907 kg). The unit is built with a low-profile wide mounting base, sealed needle roller bearings with grease fitting, and powder-coat finish for corrosion resistance.
