What is a Glass Suction Cup?

Glass suction cups are essential tools for almost any glazing job. Their strong grip makes moving glass easier while reducing the risk of injury or damage. The handles provide better control, allowing you to avoid coming into contact with its sharp edges. Thanks to their powerful vacuum and ergonomic design, suction cups enable you to manoeuvre glass into position at various angles with minimal strain.

How Do Suction Cups Work?

Although suction cups come in many types, they all work on the same basic principle. Each has a rubber seal that forms an airtight grip when pressed against a surface. By removing the air inside the cup, the pressure inside becomes lower than the atmospheric pressure outside. This creates a vacuum that securely attaches the cup to the object. Depending on the model, suction cups can hold anything from a few kilograms up to 170kg, such as those available at GGR Glass.

Types of Suction Cups

Slap-On Suction Cups

Quick and simple to use, slap-on cups are perfect for lighter glass pieces weighing up to 22.7kg. Their compact size and durable rubber build make them easy to carry between jobs.

Morkgrab Suction Cup – Designed with a four-finger handle for comfortable use, this cup prevents fingerprints on glass and has a lifting capacity of 5.4kg.

D-Cup Lifter (22.7kg) – Featuring dual cups and a finger-operated release bar, this cup offers a strong 22.7kg lifting capacity and extra support for easier placement.

Lever-Operated Suction Cups

For heavier tasks, lever-operated suction cups provide strength and reliability. The rubber suction pad, combined with an easy-grip handle and lever, makes glass lifting and installation straightforward.

GGR1 Suction Cup – A single-cup design that can lift up to 30kg of smooth materials such as glass or sheet metal, with a 120mm diameter pad for secure coverage.

GGR3 Suction Cup – A three-cup model in a triangular formation that can lift up to 80kg. The added grip offers extra security in the unlikely event one cup loses its vacuum.

Battery-Powered Suction Cups

If you need more power than a standard cup but less than a full glass vacuum lifter, battery-powered models are ideal.

Nemo Grabo Vacuum Cup – With a 170kg lifting capacity, a sturdy handle, and a rectangular pad, this tool can run continuously for 1.5 hours. It works on glass, sheet metal, wood, and other non-porous materials.

Textured and Curved Suction Cups

Not all glass is flat or smooth, and that’s where specialist suction cups come in.

Powr-Grip N6450 Curved Suction Cup – Designed with a deep concave pad, it conforms to curved surfaces and can lift up to 79kg. Its durable metal handle and quick-release mechanism make it highly practical.

Powr-Grip N4950TS Suction Cup – Engineered for textured and irregular surfaces, this model has a unique sealing edge and a lifting capacity of 27kg, making it versatile for various glazing projects.
