8" Heavy Duty Glass Suction Cup for Granite & Glass Lifting - 220lbs Capacity Vacuum Lifter with Metal Handle & Brass Pump (2 Pack) - Perfect for Countertop Installation, Window Glass Handling, and Stone Material Moving

I was initially skeptical about whether they would handle the weight and awkward angles of these windows, but I was impressed with their performance.Pros:1. Strong Suction Power: These suction cups easily handled the heavy truck windows. With a load capacity of 240 lbs, they provided a secure hold throughout the process, even on vertical surfaces.2. Durable Construction: The combination of a metal handle and ABS pump felt sturdy and reliable. They didn’t bend or show signs of wear during use.3. Easy to Use: The vacuum pump mechanism was straightforward and created a strong seal on the glass quickly. The red indicator on the pump was helpful in monitoring suction strength.4. Versatile Applications: While I used these on truck windows, they would also work well for other glass or granite lifting tasks, making them a versatile tool for any professional or DIY enthusiast.Cons:• Weight: The cups themselves are slightly heavy due to their durable construction, but this is a minor tradeoff for the load capacity and reliability.• Storage: They don’t come with a carrying case, which would have been a nice addition for transporting and storing them safely.Verdict:These suction cups are a must-have for anyone working with heavy glass or granite, especially in the trucking industry. They performed flawlessly for lifting and positioning semi-truck windows, making the job much easier and safer. Highly recommended for both professionals and serious DIYers.
