Game Bird feeder our rain shield will not leak. Our 175 lb (79.5 kg) capacity game bird feeder solves the persistent problem of keeping rain out of the feed trough. The rain shield interlocks with the body. The seamless upper shell of the body steps out over the rain shield such that rain would have to climb vertically for any leakage to occur. Our model GBF175 game bird feeder is molded from polyethylene. Hindered amine light stabilizer, the most potent ultraviolet protection, is added to maximize the life of your investment. We surveyed some of our game bird raising customers and reviewed their comments carefully when we designed these features. Add capacity with either model GBF1515 galvanized shell extension or model GBF 1520 poly extension. Add-on shell fits over the rain shield. The top poly shell fits over either Add-on shell. Adds 17 in (43.2 cm) of height. Adds about 130 pounds (59.1 kg) of feed capacity depending upon the feed being used. Total capacity with either extension about 305 lb (138.6 kg).
