Vacuum Glass Suction Cups
JS8642-4 Extra Heavy Vacuum Glass Suction Cup
An articulating dual claw with a forged steel body: 1000 g, 140 KG horizontal and 120 KG vertical suction.
Product Overview
An articulating dual claw with a forged steel body: 1000 g, 140 KG horizontal and 120 KG vertical suction. Its stated lifespan is more than three times that of a regular suction cup, and the specification explains why: steel construction, mirror-finish stainless wear pads, and a handle with double the lifespan of the previous design.
Key benefits
Why Buyers Choose This Model
Sturdy Forged Steel Body
Steel rather than aluminium, forged and crafted for wear resistance and robustness. That is the reason for the lifespan claim and the reason for the weight.
Mirror-Finish Stainless Wear Pads
Stainless steel wear pads with a mirror finish, which is where an articulating lifter wears first because the joint moves under load.
Articulating Cup And Handle
The cup and handle articulate, so the lifter attaches to flat surfaces and curved objects alike, which expands what one tool covers.
High-Strength Wear-Resistant Handle
A handle with double the lifespan of the previous design, which on a 140 KG lifter is the component that takes the punishment.
Application scenarios
Where It Is Used
- Heavy glass and ceramic tile transport
- Curved and flat panels from one lifter
- Fleet and rental use where lifespan is the purchase criterion
- Demanding site conditions
Who it is for
The Buyers This Model Suits
Rental And Fleet Operators
Buys on lifespan rather than on unit price, and the steel body and stainless wear pads are what deliver it.
Heavy Glazing Crews
Handles panels at the top of the dual-claw range and needs articulation as well.
Contractors On Demanding Sites
Works where an aluminium lifter would be worn out in a season.
Problems it solves
What It Fixes
Lifters Worn Out In A Season
The stated lifespan is more than three times that of a regular suction cup, which is a claim the steel body and stainless wear pads support.
Articulating Joints Wearing Loose
Mirror-finish stainless wear pads are specified at exactly the point that moves under load.
Handles Failing Before Bodies
The high-strength handle has double the lifespan of the previous design.
Technical features
How It Is Built
Dual-Claw Design
Suited for handling glass, ceramic tiles, and similar materials, ensuring stability and reliability.
Vacuum Suction Principle
Creates a vacuum effect when the pressure button is pressed down, facilitating efficient lifting.
Sturdy Steel Body
Constructed from durable steel material, forged and crafted for wear resistance and robustness.
High-Strength Wear-Resistant Handle
Offers a handle with double the lifespan of the previous design, providing robust performance.
Stainless Steel Wear-Resistant Pads
Enhances wear resistance and durability.
Articulating Design
Suction cup and handle articulate, securely attaching and lifting flat surfaces and curved objects, expanding its applications.
Enhanced Suction Cup Design
Larger suction cup size translates to deeper concavity, resulting in stronger suction, improved safety, and stability.
Thick Nitrile Rubber Pads
Made through precise compression from natural odorless materials, these pads offer strong suction and long-lasting adhesion.

Materials and manufacturing
How This Model Is Made
Parts for the JS8642-4 are produced in our own workshops in Jinli Town, Zhaoqing. This model uses both routes: its moulded components come off our five horizontal and three vertical injection moulding machines, and its metal parts come off our fifteen automatic punching machines, nine automatic lathes and three welding machines. Tooling is designed and cut in our own mould room, which is why a change to this model does not queue behind another factory's schedule.
Quality Control
- Every model is weighed against its declared net weight during production, so the carton weight on your packing list matches what arrives.
- Stamped parts are produced in house on 15 automatic punching machines and 9 automatic lathes, so dimensional consistency is controlled at source rather than inspected on arrival.
- Moulded parts come off 5 horizontal and 3 vertical injection moulding machines running up to 10,000 mould open-and-close cycles per day, with tooling maintained in our own mould room.
- The quality management system was certified to ISO 9001:2015 in August 2023, with a certificate valid to 31 July 2026.
- Cartons are counted against the packing list as they are loaded into the container at our own factory door.
Certifications
The quality management system was certified to ISO 9001:2015 in August 2023, under standard GB/T19001-2016, for the manufacture and sale of glass caulking guns and sealant guns. The certificate on file runs to 31 July 2026; ask us for the current renewal status before relying on it. A TUV Rheinland assessment was obtained in 2016.
Customisation Options
- Aluminium Tube Anodizing And Colouring: More than 10 colours available; the surface can be given a frosted texture.
- Aluminium Tube Painting: Up to 10 colours with customisable patterns.
- Aluminium Tube Laser Engraving: Engraved logos, text and patterns on stamped fittings and aluminium tubes.
- Self-Adhesive Logo Labels: Applied to the product in the position the buyer specifies.
- Multi-Colour Logo Printing: Paint screen printing in any colour, with several colours printed at once.
- Tag And Product Screen Printing: Screen printed tags and product markings, multi-colour capable.
Use guide
Getting The Best Out Of It
Step 1
Set and lock the articulation angle before applying the cups to the panel.
Step 2
Clean and dry the surface; the rating assumes a clean, smooth, non-porous panel.
Step 3
Seat both pads flat and draw both vacuums, confirming both hold before taking weight.
Step 4
Release both vacuums and check the stainless wear pads at the joint as part of routine inspection.

FAQ
JS8642-4 Questions
What are the load ratings?
140 KG horizontal suction and 120 KG vertical suction, at 1000 g net weight.
What is the lifespan claim based on?
Our product description states a lifespan more than three times that of regular suction cups, attributed to the forged steel body, mirror-finish stainless wear pads and the high-strength handle. It is our own figure, not an independently tested one.
Does it articulate?
Yes. The cup and handle articulate, so it attaches to flat surfaces and curved objects, which expands its applications beyond a fixed dual claw.
How is it packed?
One piece per inner box, 10 pieces per master carton at 40 x 80 x 62 cm. Stock colour is yellow.
Are the nitrile pads replaceable?
Yes. The thick nitrile rubber pads are precision compressed from natural odourless material and are stocked as spare parts.
