JS8642-2 Heavy duty double 2 claw aluminium sucker for glass lifter
A heavy-duty double-claw aluminium sucker at 795 g, rated 130 KG level suction and 110 KG vertical, finished in black.

Product Overview
A heavy-duty double-claw aluminium sucker at 795 g, rated 130 KG level suction and 110 KG vertical, finished in black. It sits at the upper end of the standard dual-claw bodies, above the 90 KG JS8642 and below the articulating and extra-heavy models.
Why Buyers Choose This Model
130 KG Level Suction At 795 g
The best load-to-weight figure among the fixed dual claws: 44 percent more level capacity than the JS8642 for 45 g more weight.
Aluminium Sucker Body
An aluminium body rather than steel, which keeps the weight down while holding the two pads in plane.
Black Finish
Supplied black as stock, which suits professional ranges and marks less visibly than a light finish.
20 Per Carton
One per inner box and 20 per master carton at 52 x 34 x 42 cm, the standard dual-claw carton so it substitutes cleanly in a mixed load.
Where It Is Used
- Heavier glass panels than a standard dual claw takes
- Glass lifting where two claws are preferred over three
- Professional glazing and tiling
- Distributor ranges needing an upper dual-claw tier
The Buyers This Model Suits
Glazing Contractors
Handles panels above the 90 KG dual-claw rating but does not want the bulk of a three claw.
Glass Lifting Operations
Moves panels repeatedly where load-to-weight matters across a shift.
Distributors Filling The Gap
Sits between the 90 KG JS8642 and the 140 KG JS8642-4.
What It Fixes
The Gap Between 90 And 140 KG
Without this model a customer needing 120 KG has to jump to a much heavier lifter.
Weight Carried All Day
795 g for 130 KG level capacity is a better ratio than any other fixed dual claw here.
Orientation Confusion
130 KG level and 110 KG vertical are different numbers. Specify against the orientation used.

How This Model Is Made
Parts for the JS8642-2 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; any contamination reduces the achievable load.
Step 2
Seat both pads flat before drawing either vacuum.
Step 3
Use 130 KG for level lifting and 110 KG for upright carrying, with margin for surface condition.
Step 4
Release both vacuums before storage and inspect the pads for hardening or embedded grit.
