Vacuum Glass Suction Cups
JS8643 three-claw vacuum suction cup
The base three-claw lifter: 1050 g, 115 KG horizontal and 100 KG vertical suction, in precision-pressed aluminium alloy with a triangular disc support.
Product Overview
The base three-claw lifter: 1050 g, 115 KG horizontal and 100 KG vertical suction, in precision-pressed aluminium alloy with a triangular disc support. The 7 mm thickened nitrile pad and the engineering ABS latch are the two components that decide how a three claw behaves in service.
Key benefits
Why Buyers Choose This Model
Triangular Disc Support
Force is distributed through a triangular support rather than along a bar, which raises stability and effectively prevents unexpected detachment. That geometry is the reason three claws exist.
7 mm Thickened Rubber Pad
A 7 mm pad gives stronger suction and a more secure fit, maintaining adhesion across various surfaces. Pad thickness is what lets a cup conform to a slightly imperfect panel.
Engineering ABS Latch
An engineering-grade ABS latch with anti-slip grooves at the pressing area, so the latch is operable with a gloved or wet hand.
Precision-Pressed Aluminium Alloy
The body is pressed from aluminium alloy for pressure resistance and anti-drop capability, giving stability and durability in operation.
Application scenarios
Where It Is Used
- Larger glass panels needing three points of contact
- Household and industrial panel handling
- Glass shop and site work on smooth surfaces
- The entry point of the three-claw range
Who it is for
The Buyers This Model Suits
Glazing Contractors
Handles panels large enough that two pads allow flex, where the triangular support controls it.
Glass And Stone Handlers
Moves smooth-surfaced panels in workshop and site conditions.
Distributors Entering Three-Claw
The base of the three-claw range at 115 KG, below the export and PowerMax versions.
Problems it solves
What It Fixes
Panels Flexing Between Two Pads
A third pad and the triangular support stop the panel bowing between contact points.
Latches That Cannot Be Worked With Gloves
Anti-slip grooves at the pressing area make the ABS latch operable in real conditions.
Pads That Cannot Conform
7 mm of nitrile gives enough compliance for a panel that is not perfectly flat.
Technical features
How It Is Built
Alloy Monolithic Construction
Crafted from aluminum alloy through precision pressing, ensuring exceptional pressure resistance and anti-drop capabilities. This structural design guarantees stability and durability during operations.
Triangular Disc Support
The unique triangular disc support system disperses force through triangular support, enhancing the stability of the suction cup and effectively preventing unexpected detachment.
Thickened Rubber Pad
Equipped with a 7mm thickened rubber pad, providing a stronger suction force and a more secure fit. Outstanding adhesion is maintained on various surfaces, ensuring excellent adhesion performance.
Engineering ABS Latch
Designed with an engineering-grade ABS latch featuring anti-slip grooves at the pressing area, facilitating effortless operation while offering reliable support. This design ensures easy and efficient handling.
Anti-Slip Handle Design
Prioritizing user experience and safety, the suction cup incorporates an anti-slip handle design for comfortable grip and increased usability while ensuring safety during use.
Simple Locking Mechanism
Featuring a user-friendly locking mechanism, a single press and release complete the operation swiftly. This design simplifies the process and enhances operational efficiency.
Premium Nitrile Rubber
Employing high-quality nitrile rubber with excellent oil, abrasion, and heat resistance, along with strong adhesive properties, ensuring enduring performance under various conditions.
Increased Support Surface
The larger support surface of the suction cup provides greater stability during handling, resulting in less effort. This accommodates objects of varying sizes, improving operational efficiency.

Materials and manufacturing
How This Model Is Made
Parts for the JS8643 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.

Getting The Best Out Of It
Step 1
Clean and dry the panel across all three contact areas, not just one.
Step 2
Seat all three pads flat before operating any latch.
Step 3
Draw all three vacuums and confirm each holds before taking weight.
Step 4
Release all three before storage and inspect each 7 mm pad for hardening, cracking and embedded grit.

FAQ
JS8643 Questions
What are the load ratings?
115 KG horizontal suction and 100 KG vertical suction, at 1050 g net weight.
What does the triangular disc support do?
It distributes force through a triangular support rather than along a single axis, which enhances stability and effectively prevents unexpected detachment. It is why a three claw behaves differently from two dual claws.
How thick is the pad?
7 mm of thickened nitrile rubber, chosen for oil, abrasion and heat resistance and for strong adhesion across various surfaces.
What colours are available?
Yellow, golden, silver and black as stock, plus custom colours.
How is it packed?
One piece per inner box, 10 pieces per master carton at 46.5 x 35 x 49.5 cm.
