The 'Griplock' Squirrel-Proof Tube Feeder gives backyard birds reliable access to seed while making squirrels work against a system specifically engineered to stop them. Its compact 1.3-pound capacity, weight-activated shroud, and negative grip tube make it a strong everyday choice for birders who want squirrel resistance without stepping up to a larger high-capacity feeder.
When a squirrel climbs onto the feeder, its weight forces the metal mesh shroud downward and closes access to the seed tray. The negative grip tube adds another layer of defense by preventing squirrels from hanging from the wire support and bypassing the closing mechanism.
Scientific Engineering
Weight-Activated Squirrel Protection: The metal mesh shroud lowers under squirrel weight and blocks access to the seed tray without harming the animal.
Negative Grip Tube: Prevents squirrels from gripping the wire hanger with their hind feet and hanging alongside the feeder to defeat the closing mechanism.
Seed Ventilation System: Upper vents allow warm, humid air to escape while fresh air enters through the lower seed openings, helping seed stay fresher.
RoxResin Components: Waterproof, rust-proof, UV-stabilized components are designed to withstand repeated outdoor exposure and are dishwasher-safe.
Compact 1.3-Pound Capacity: Holds approximately 3/4 quart of seed for manageable refilling and routine cleaning.
Hanging Installation: Designed for suspended placement from a feeder hook, pole arm, or other suitable support.
Boutique & Conservation Values
Protects the Seed Supply: Squirrel exclusion helps reserve purchased seed for the birds the feeder is intended to support.
Supports Fresher Feeding: Ventilated seed storage helps reduce trapped heat and humidity inside the tube.
Broad Bird Appeal: Attracts a wide range of clinging and perching birds, including chickadees, cardinals, grosbeaks, woodpeckers, nuthatches, and finches.
Durable Outdoor Design: Weather-resistant components support long-term backyard use with routine care.
Steward's Insight
Give this feeder at least 16 inches of clearance from branches, railings, walls, poles, or other footholds. That forces a squirrel to put its full weight onto the feeder, which is what activates the closing mechanism. Black oil sunflower, safflower, and mixed seed blends are all suitable choices.
