Heavy-duty 8-inch double-thickness glass suction cups (2-pack) – engineered for safe, secure lifting and handling of large glass panels, tiles, windshields, mirrors, granite slabs, metal sheets, stone countertops, solar panels, aquarium glass or other smooth, non-porous surfaces up to 880 lbs total vertical load capacity (440 lbs per cup when used correctly). Each cup features a built-in pressure gauge for real-time vacuum monitoring, ensuring maximum safety and reliability during lifts.
Key Features:
- 8-inch diameter pads – large, double-thick rubber pads (high-grade natural rubber or silicone composite) create powerful, long-lasting vacuum seal – superior grip on flat, smooth surfaces with excellent edge sealing to prevent slippage.
- 880 lbs total load rating – tested vertical holding capacity per pair (440 lbs per cup) under ideal conditions – provides confident handling of heavy glass, tiles or stone; always use both cups together for maximum safety and load distribution.
- Pressure gauge on each cup – analog vacuum gauge shows real-time suction level (green safe zone) – alerts you instantly if vacuum drops, allowing immediate correction before lift or movement.
- Ergonomic pump handle – easy-to-operate plunger-style pump with red-line indicator – push to create vacuum, pull release tab to detach; spring-loaded plunger locks in place for sustained hold.
- Double-thickness pad – extra-thick rubber pad enhances durability, conforms better to minor surface imperfections and maintains seal longer than standard single-thickness cups.
- Rust-resistant metal components – zinc-plated or stainless steel hardware resists corrosion – suitable for indoor/outdoor use, humid environments or construction sites.
- Wide applications – perfect for professional glaziers, tilers, installers, fabricators, auto glass replacement, countertop handling, large mirror mounting or DIY home projects involving heavy sheet materials.
- Safety & ease of use – no electricity or batteries needed; quick attach/release; test vacuum seal before lifting; always use with proper lifting technique and safety gear.
Ideal For:
- Lifting and positioning large glass panels, windshields or shower doors
- Handling tiles, granite slabs, marble or stone countertops
- Professional glazing, tiling, construction or fabrication work
- Moving heavy mirrors, solar panels or aquarium glass
- Safe, reliable one- or two-person lifts without suction loss
This 2-pack of 8-inch heavy-duty suction cups with pressure gauges offers professional-grade holding power, visual vacuum confirmation and durable construction – a must-have tool for safe, confident handling of heavy, smooth materials in glass, tile or stone work. Always verify seal with gauge and use proper lifting supports for loads near maximum capacity.
