The GC advantage
Ridiculously simple.
Seriously scalable.
You already invested in a Knockbox workflow. Add the closing step you need—not an entirely new production line.
VS.
Nearly 10× the upfront equipment price.
The RollCraft ATC was advertised at $24,995 in August 2026. GC is designed for compatible Futurola Knockbox workflows; other manual systems may use their own trays and may be priced differently. Confirm current price, included components, compatibility, and throughput before comparing. View source ↗
Maintenance without the mystery
No motors, sensors, pneumatics, or software stack. Clear components keep contact areas visible, and replacement parts are available.
Scale one station at a time
Add another Crimper and train another operator. No facilities project, power drop, air line, or production-line rebuild required.
Keep the workflow that works
Built to follow compatible Futurola Knockbox production rather than forcing your team onto an entirely different filling system.

Production questions
Before it goes
on the line.
What operators need to know before replacing hand-twisting with batch closing.
Which model do I need?
Choose the recommended 0.5g Complete Kit for 84 mm cones or the 1g Complete Kit for 109 mm cones. Each includes the full five-piece closing station. Confirm your exact Knockbox tray and cone specification before ordering.
Does it replace the Knockbox?
No. Your compatible Futurola Knockbox fills and packs the cones. The GC Crimper takes over the separate closing step, forming a Dutch-crown finish across the batch.
What comes with it?
Every kit includes a holding piece, closing piece, 9× exporting piece, catch plate, and catch-and-store container. Replacement parts are available.
Does it need power or a mechanic?
No. The Crimper is manual: no motor, compressed air, software, sensors, or complicated controls. Operators learn a repeatable physical workflow, and there is no motorized closing mechanism to service.
How does direct checkout work?

Fixed shipping for each complete kit is $199 to the contiguous United States, $399 to Alaska or Hawaii, $499 to Canada, and $899 to other international destinations.
