Three machines, three very different jobs. This is the conversation we have on the phone most often, written down. If you only read one line: RCV2 if you walk to the load, RCV3 if the load comes to a bench, RCV9 if the load comes down a line.
The 30-second answer
| Question | RCV2 handheld | RCV3 tabletop | RCV9 automatic arch |
|---|---|---|---|
| Where do you strap? | Anywhere — pallets, racks, the truck | One fixed packing bench | A production or shipping line |
| How many a day? | Up to a few hundred | A few hundred to ~1,000 | 1,000+ (up to 24 per minute) |
| What are you strapping? | Pallets, lumber, bundles, cartons | Cartons, boxes, printed matter | Cartons and bundles of a similar size |
| Strap | PP or PET, 1/4"–3/4" | PP, 1/4"–5/8" | PP, 3/8"–5/8" |
| Tension | 100–1,011 lbs (450–4,500 N) | 11–110 lbs | 11–110 lbs |
| Power | 14.4V battery (~350 straps per charge) | 110V outlet | 110V outlet, 400W |
| Price | from $399.95 | $1,045.95 | $4,998.95 |
When the RCV2 handheld is the right call
The RCV2 is the only one of the three that is not tied to a spot. It weighs 7.5 lbs, runs on a 14.4V battery, and tensions, friction-welds and cuts in one motion with no metal seals. It is also the only Rockcub machine that runs PET strap, which matters if you strap pallets, lumber or anything heavy: PET holds tension and the RCV2 will pull up to 4,500 N (1,011 lbs).
Choose it if:
- You strap pallets or bundles where they sit, not on a bench.
- Your loads vary — a carton one minute, a pallet of lumber the next.
- You want one tool for a crew of two or three people to share.
What it is not: a machine for 800 identical cartons a day. It can do it, but your wrists will tell you the RCV3 was the better buy.
When the RCV3 tabletop is the right call
The RCV3 sits on casters at bench height (25.8"). You wrap the strap around the carton by hand, push the end into the slot, and the machine tensions, heat-seals and cuts in under three seconds. Tension runs 11–110 lbs — deliberately lower than the RCV2, because it is built for cartons, not pallets, and you do not want to crush the box.
Choose it if:
- Packing happens at one station and the boxes come to you.
- You strap the same kind of carton over and over.
- New staff need to be productive on day one — there is nothing to learn beyond "wrap, insert, done".
Note the open tabletop: there is no maximum package size, only a minimum of 2.4" × 2.4". It plugs into a normal 110V outlet and ships by freight with liftgate delivery included.
When the RCV9 automatic arch is the right call
The RCV9 is a different category. The strap is already in the arch; you slide the carton in, and a foot pedal, the tabletop ball switch or continuous mode fires the cycle — about 2.5 seconds, up to 24 cycles a minute. Nobody wraps anything by hand.
Choose it if:
- You strap in volume on a fixed line and strapping is currently the bottleneck.
- Your packages fit the 31.5" × 23.6" arch and weigh up to 176 lbs.
- You have about 6.6 × 4.9 ft of flat floor and a standard 110V outlet — no three-phase, no electrician.
It is a 331-lb machine that arrives in a crate by freight (liftgate included), so read our RCV9 site-prep checklist before it ships.
Three common mistakes
- Buying the RCV3 for pallets. 110 lbs of tension and PP strap is right for cartons and wrong for a pallet of lumber. That job is the RCV2 with PET strap.
- Buying the RCV2 for a packing line. A handheld tool at 500 cartons a day is a fatigue problem. Put the cartons on an RCV3.
- Buying the RCV9 too early. Below roughly 1,000 packages a day the RCV3 does the job for a fifth of the price. Above it, the RCV9 pays for itself in labor within months.
Still strapping steel?
None of the three machines runs steel strap. For lumber, pipe and brick that genuinely need steel, we sell the manual RCV4 and RCV5 tensioner-sealers and steel strap. For most other loads, PET on the RCV2 has replaced steel — see why.
FAQ
Can one strap work in all three? 5/8" PP does: the RCV2, RCV3 and RCV9 all accept it. PET only runs in the RCV2.
Do I need seals or clips? No. All three weld the strap to itself — friction weld on the RCV2, heat seal on the RCV3 and RCV9.
What about support? All three carry a 1-year warranty and are supported from our warehouse in Whittier, California, where the wear parts are stocked.
