| Model | Type | Strap Material | Strap Width | Tension Range | Best For |
|---|---|---|---|---|---|
| RCV2 (this machine) | Handheld electric | PET / PP | 7–19mm (0.28–0.75") | 450–4,500N (100–1,011 lbs) | Mobile use around the warehouse, mixed carton & pallet work |
| RCV3 | Semi-automatic tabletop | PP | 1/4"–5/8" (6–16mm) | 11–110 lbs | Repetitive carton sealing at a fixed station |
| RCV9 | Automatic arch | PP | 3/8"–5/8" (10–16mm) | 0–110 lb | High-volume lines, up to 24 cycles/min |
The RCV2 is the only Rockcub machine that works with both PET and PP straps, and its battery-powered handheld design means it isn't tied to a fixed packing station — take it anywhere in the warehouse.

Smaller items — parts, accessories, strap and film — ship by UPS or FedEx with tracking. Large machines ship by freight on a pallet, and liftgate service is included at no extra charge: the driver lowers the shipment to ground level, so no loading dock or forklift is needed on your end.
Someone needs to be available to receive and sign for a freight delivery. Inspect the shipment for visible damage and note it on the delivery receipt before signing.
