The classic arc barrel for extension, flexion and side-bending work, shipped with the F2 System package already in the box. That is the difference between this listing and the plain Spine Corrector, and it changes what the apparatus is for.
The F2 connectors install into the barrel's prepared ports in place of the standard covers. Two yellow springs clip in with carabiners, and the levers double as handles that position wrists and shoulders for weight-bearing exercises. Springs attach at multiple angles and resistance levels, so the barrel loads movement rather than only supporting it.
At 27.6 lb and 38.6 in long, it is the lightest way into BASI's spring system and it stores against a wall between sessions. The mechanism is covered by patents US10330135 and EP3171948.
What's Included:
- Spine corrector barrel
- 2 F2 connectors
- 2 rubber handles
- 2 neoprene handles
- 2 carabiners
- 2 yellow springs
Features
F2 System in the box
Connectors, levers, springs and handles all included. Bought separately against a plain spine corrector, the F2 package costs most of the difference between the two listings.
Springs at multiple angles
The connectors let springs attach at different angles and resistance levels, which is what turns a barrel from a support into a loading apparatus.
Levers double as handles
They are shaped to be held, putting wrists and shoulders in a strong position for weight-bearing work rather than asking a hand to grip a spring end.
Lightest route into F2
27.6 lb and 38.6 in long. Of everything in the range that takes the F2 System, this is the piece that can be carried by one person and stood against a wall.
Shares kit with the rest of the range
F2 components move between BASI apparatus, so a connector bought here works on a chair, a barrel or a reformer with prepared ports.
Patented mechanism
US10330135 and EP3171948 cover the F2 arrangement, which is BASI's own engineering rather than a generic spring bracket.
Installation
Part-built in the crate
The frame arrives as one assembly and the loose components go on afterwards: footbar, ropes, pulleys, spring holders and the tower or trapeze structure if your configuration includes one. Ordinary hand tools, and the fixings are packed with it.
Allow the time and the second person
Two to four hours on the larger frames, one to three on a plain reformer, two people throughout. These frames weigh between roughly 150 lb and 330 lb, which is the reason rather than the difficulty of the job.
The route matters more than the room
Delivery is kerbside. Check door widths, the turn at the head of any staircase and your ceiling against the tower or trapeze height in the specification table, before the truck arrives rather than after.
Commission it before you load it
Run the carriage from end to end a few times so the wheels seat, measure both ropes against each other, and confirm the footbar and spring holders lock in every position before you work at full spring load.

Resources
Warranty, Shipping and Returns
Cover is set by BASI Systems and differs by component. The main wooden frame and structural woodwork run to ten years. Metal profiles and components, F2 hardware, springs, plastic parts and fasteners run to two years. Elastomer-coated parts, meaning the footbar, hand bar, pedals, stoppers, handles and wheels, run to one year. Mats, upholstered surfaces and fabric accessories run to ninety days. Everything is measured from the invoice date and applies to the original purchaser, and it does not pass on if the apparatus is sold.
Read the spring clause before you file the paperwork. On spring-loaded apparatus, BASI expects springs changed at two years or 3,000 hours of use, whichever lands first, and warns that failing to do so may void cover.
Delivery inside the United States is free. Crated apparatus travels on a freight truck and the carrier rings to fix a window with you, handing over at the kerb rather than carrying it inside, so have a second person and a measured route ready. Parcel-sized items generally arrive 7 to 10 business days from dispatch.
Sign nothing before you have looked. Damage or a missing carton has to appear on the Proof of Delivery at the moment of delivery, with the claim raised inside five business days, or the manufacturer declines liability.
Unused equipment in its original packaging can be returned for 30 days from delivery, with no restocking fee and refunds settled within 7 business days of arrival. Cancelling before the apparatus leaves the factory is free.
About BASI Systems
BASI Systems builds the apparatus used across BASI Pilates, the education body Rael Isacowitz founded. Because the two sit together, the catalogue is planned as a fleet: the same extension legs raise a reformer, a Cadillac or a raised mat and the same F2 spring system moves between a chair, a barrel and a reformer through ports that are prepared from new.
Materials do not change with the price. Beech hardwood frames, aircraft-grade aluminium for tracks and load-bearing hardware, orthopaedic padding under anti-slip antibacterial vinyl. Patent US 10,393,163 B2 covers the spring positioning system, and the Wunda Chair has an A Design Award.
