8" Glass Suction Cups with Pressure Gauge, 2 Pack Vacuum Suction Cups with Metal Handle, Heavy Duty Hand-held Suction Cups for Glass & Granite Lifting, 440 lbs Load Capacity with Carrying Case

Impressive Load Capacity: Each suction cup features a load capacity of 440 lb, constructed from a special three-layer rubber pad that operates effectively in temperatures ranging from -20 to 60. Thanks to the expertly engineered base, it adheres firmly to various surface types and maintains suction for approximately 6 to 8 hours. Real-time Pressure Monitoring: Instantly verify your suction is secure! The vacuum suction cup lifter's pressure gauge clearly displays the status: The Green Zone indicates a safe vacuum range. Should the Red Zone or the red warning line appear, it signifies a dangerous vacuum range; continue pressing the button until the pointer returns to the green zone. Ergonomic Metal Thickened Handle: The glass suction cup pad is crafted from durable, odorless, high-strength rubber paired with an all-metal handle for a robust and ergonomic grip. Unlike plastic handles, this reinforced metal construction resists warping or degradation even under heavy, repeated use. Widely Used: This 8" all-metal heavy-duty hand-held vacuum lifting plate attaches swiftly to flat, smooth, nonporous surfaces. This suction cup is excellent for lifting and moving materials such as large glass, tile, aquarium panels, furniture, plastics, metal, stone slabs, and appliances, making it a superb choice for material handling.
