Open Face Corner Block (PCA-1270) & Automatic Release Device (PCA-1291)
Portable Winch Co.
For use with ropes up to 1/2" diameter.
An ingenious way to release the rope from the pulley to allow a log to ‘turn’ into the trail. Depending on the distance the anchor tree is from the trail, you may adjust the automatic release to make the rope slip out of the pulley at the appropriate moment. Simply turn the chain link one-half turn around the rope and insert it into the metal cartridge.
