Maximum Reach for Deep Column and Wall Consolidation

Tackle the deepest pours and most challenging job site geometries with the Multiquip FS21 Flexible Shaft. At an impressive 21 feet (6.4 meters) in length, this shaft provides the extended reach necessary for vibrating tall columns, deep wall forms, and extensive footings without moving your power unit. Engineered for professional durability, the inner core is wound from high-carbon spring wire, specifically designed to resist unraveling and stretching under the heavy torque loads of concrete consolidation.

Built to survive harsh construction environments, the FS21 features the industry's strongest outer casing—a rugged composite of flat steel wire reinforcement, steel wire mesh, and a tough, abrasion-resistant rubber jacket. This multi-layer design protects the rotating core from kinking and crushing damage. The integrated quick-disconnect coupler ensures fast, tool-free attachment to Multiquip CV2 and CV3 electric motors or G55H gasoline drive units. Whether you are driving a compact 1400HD head or a massive 2600HD steel head, this shaft delivers reliable power transfer to ensure structural integrity and a smooth finish.

Key Features

  • Extreme Reach: 21-foot length is ideal for deep forms, tall columns, and large-scale foundation work.
  • Heavy-Duty Core: Inner core made from high-carbon spring wire to prevent stretching and breakage.
  • Armored Casing: Extra-thick outer shell with steel reinforcement resists kinking, wear, and job site abrasion.
  • Quick Connection: Features an integrated quick-disconnect coupler for rapid setup with drive motors.
  • Versatile Compatibility: Works seamlessly with Multiquip CV2, CV3, BP25H, and G55H drive units.
  • Wide Head Range: Compatible with all RHV steel heads from 1-3/8" (1400HD) to 2-5/8" (2600HD).
  • Sealed Design: Double seals at the shaft end prevent grease leakage and concrete contamination.

Pro-Tip: Due to the 21-foot length, it is critical to avoid tight bends during operation. Keep the shaft as straight as possible to minimize internal friction and heat buildup. When storing, coil the shaft loosely (avoiding kinks) to prolong the life of the inner core and outer casing.

So small
Size: 10.5, Color: Allblack015
They seemed comfy enough, but the sizes are very small compared to my typical shoe size. Buy at least a whole size up if youre going to get these

ULTRA LIGHTWEIGHT EVERYDAY SNEAKER
Size: 12, Color: Grey015, Size: 12, Color: Grey015
You should know that if you're specific on your footwear like I am, these may be the shoes for you. All too often shoe companies make shoes that look stupid by trying to do too much. These shoes are great because the most important appearance in a shoe is what they look like on feet from your POV. The toe box is spacious and the lace front is normal, not too wide like Adidas Ultraboost. The only downside is these shoes wear out quickly. They last about 1 year with daily use before the outsole starts to to go. All in all price for value, 5/5.

Sizes run smaller, at least for me
Size: 9, Color: Allblack015
I have a 8.5/9.0 size shoe, depending on the manufacturer. I purchased these exclusively for work, on a slippery (paper dust) concrete floor and a forklift. The main con here is there is NO size 9.0, only 8.5 or 9.5. I think this is odd, but I am sure there is some reason for it. Nonetheless, I ordered the 9.5 in black. I was expecting it to be a little large. However, this shoe fits me perfectly. Thus my reasoning that, for me, these run small. These stretch. They are not constrictive. I despise tight constricting shoes since they usually hurt my feet. I also hate shoes that are too big as they tend to make me trip (I am already uncoordinated). They have a softer rubber/plastic'y sole. I dont know the material, other than "Phylon". I have only worn for two weeks and they are comfortable. I do feel their flexibility. These shoes are not a stiff shoe. For me, that is a plus. However, non slip they are not. In defense, I have not experienced any shoe that is non slip on the floor at my work. The smooth concrete floor is often covered in a finite paper dust. This makes it slippery and no shoe can stand up to my lack of coordination. My biggest like is they are very breathable. My feet sweat! During the hot days, I need my feet to breathe. These do that quite well. Also, I enjoy and actual solid sole. Some other "fancy" shoes I purchased were comfortable, but they had a very thin tread and wore out quickly. They did not last long. Time will tell if these last long. Another plus for these shoes, is there is very little text on the shoe. The only text is on the tongue of the shoe. They are also easy to put on, almost like a slip on shoe that does not fall off. Out of the box (and still now) there are no defects. It appears to be well put together. If I can get 8 months use out of these, I will be absolutely buying again.

$30 descent shoe with Foam sole no arch support
Size: 13, Color: Lightgrey015
I got these and they were in plastic smashed together to conserve space. I cut the plastic wrapper and put them on. They are a minimalist shoe. Not much support. It's like they tried to copy the sketchers, but took out 25% of the quality. It's a good soft foam sole, light weight and slip on. I wore these for nearly 9 hours on concrete at my job with out foot pain. For under $30 shoe you probably won't be able to build a sole that is arch supportive and made for longevity. If your going out for a few hours around the town, these will be comfortable. I am ditching the inserts and putting in real inserts to see if these will work for multiple purchases. Great styling no issues with build quality that I can see. Again these are under $30 not $75, so if your expectation is a durable shoe good support these are not for you. On the other hand they're comfortable for going out shopping and eating out while looking descent. I wouldn't wear these for more then a few hours as they're not really proper fit shoes with arch supports.
