Works Bell is Japan's premier interior performance company, well known for their Rapfix series of quick releases. The Rapfix Racing uses a patented ball locking design which will not come off during driving but allows for quick and easy removal. No play whatsoever, this is the ORIGINAL! The piece is a cold forged aluminum body, which is track tested and proven by the top Japanese race drivers. Makes it easier to get in and out of your car, and also provides added security when parked.

This quick release will only bolt to 3 bolt patterned wheels and welded on hub shafts. This is NOT a hub, welding is required in order to use this. This is meant for race applications and experienced experts only.

The height is 2.5" tall, so in some cases it may place the wheel to close to the driver. In cases as such, you may consider calculating distance before welding from the distance between the driver and steering wheel.

Mechanics
Eight holes grooved in the plug side match the delicate steel balls used in the bearing. This provides a firm lock for both radial and lateral movement. The steel balls are released into the Â"free” position when the sleeve is pulled, then the socket can be detached from the plug. The sleeve section, once pulled, is locked. Once remounted onto the plug section, the sleeve automatically locks back into position.

Characteristics
When reattaching a separated Rapfix unit back onto it's hub, the position of the wheel does not matter due to the fact that the Rapfix will only lock back into place in the same position in which it was disconnected. Other quick release mechanisms require the wheel to be positioned in a specific location before reattaching the wheel. Furthermore, Works Bell's unique technology ensures that there is no shakiness or play because the steel balls keep constant and consistent pressure on the plug at any time. Therefore, it plays a big part in the driver's severe steering wheel operation. In addition, in order to establish the reliability of Rapfix Racing in a race, a new mechanics, Cam Lock, whick certainly locks the radial loads by combining the plug and the socket, is adopted. Therefore, security is guaranteed by putting the Cam Lock System together with the Ball Lock System.

Specifications
It is developed especially for formula cars. Chromium molybdenum steel SCM435 is used for the plug in order to weld the steering shaft easily; SUS420 is used for the liner in order to realize the lightweight and high-strength of sleeve. Moreover, the socket made byextra super-duralumin (A7075T6) and special plating fulfills the endurance. Assuming the hard use of the plug top, protective cap is installed. It is possible to change the damage protective cap to a new one.

Strength
Rapfix Racing cleared the NAPAC standard (a standard for after market products in Japan). A screwing test was done to check the operation of steering wheel to radial power. There was not any change in the shape after being pounded by dead loads of 29.7kg.m (291N.m). Moreover, there was not any change in the shape after a bending test of dead loads of 19.8kg.m (194N.m) in order to examine the effect when a driver impacts the steering wheel in an accident.

According to the results of these tests, although the bending test and screwing test based on regulation loads caused the permanent transformation and the shakiness increased, the product is still possible to be detached and attached and it is not broken. Therefore, these tests prove that the steering wheel can still be operated when large loads act. According to these results, Rapfix Racing has the same or more strength than the spline style Quick Release Hub of other companies.

Works Bell has also tested that how much can be released when the plug and socket are pulled strongly. They were not destroyed by 3754kg(36.8KN). The test was ended when the bolt, which is fixed to the steering wheel, was destroyed. The quick release function can be still operated. Therefore, it is confirmed that Rapfix Racing could endure the pull power of 68G because the standard weight of a driver according to Japan Safety Standard is 55kg. We did 10,000 times repeated attachment and detachment tests for testing the endurance. We proved that there is no broken and it is still possible to drive, attach and detach, although the shakiness increased.

OPTIONAL: If you would like to use a standard 6 hole PCD for the quick release, Works Bell offers an adapter which will allow you to use any Sparco, Momo, Personal, Nardi or same P.C.D. steering wheel. Select the option above if desired.

Electric Contact Kit: Used for weld type only. 12 electric contacts can be added for weld type by installing this kit. The contact part can be released together with the steering wheel.

NOTE: Torque spec is 30N - m (23 ft/lbs)

Packaging contents
Color: Grey, Size: 34"- 3 Panel
Item is as described however this one appeared to be open and some parts possibly used. Example pole packaging mislabeled one had the letter K as a part there is no letter K item in the instructions. Another pole part had a taped on letter A which is completely different from the others thus indicating that it was opened or substituted. Finally after the partition was completely put together one of the bottom screw connection anchors came out making the partition unable to stand. I'm going to have to rig something up in order to get the anchor connected to the bottom panel. In closure the partion could be very acceptable and do the job if it was new and parts labeled correctly. I have pictures of all parts and packaging errors. Would buy again if new. I'm going to pursue some kind of compensation.

Great product
Color: Grey, Size: 34"- 6 Panel
This room divider is great. It was easy to put together. I was worried about it standing up right and not falling over. It stays up perfectly and is very easy to move and adjust to the shape I want it. Also, from one of the videos I watched it looked like the fabric was puckered in the panels. That is not the case at all. The fabric fits tightly in each panel for a nice smooth look. I would definitely recommend this and would buy again if needed.

Awful.
Color: Black, Size: 22"- 4 Panel
Easiest one star review ever. I'm writing this with bloody fingers from assembling this. Multiple poles were bent, none of the pole connectors worked, the hex wrench broke in my hand, the screws didn't really go into the holes provided (I had to get a friend with a press drill to widen the holes to make it work), there are sharp edges on the poles where there is a seam, and doesn't look that great once assembled. Easy do not buy, the only reason I didn't return is because it would have been tough to disassemble the half I got through in the first 5 hours of building (mostly spent fixing the product delivered)

Sturdy, Easy to Set Up, and Looks Great
Color: Grey, Size: 34" - 3 Panel
I’m really happy with this RANTILA 3-panel room divider. It was simple to set up, stands securely on its own, and gives plenty of privacy. The height is perfect, and the panels look clean and modern in my space. It’s lightweight enough to move around but still feels sturdy. Overall, a great divider that works exactly as I needed.

Not 6 ft
Color: Grey, Size: 34" - 3 Panel
I bought this for filming my auditions. I am 5’4” .The height lists is 6 ft but the fabric only reaches 5’9 1/2 “! when I must film myself head to toe, the top bars are showing. It’s easy to set up. But when I film I must tilt my camera to keep the top bars out of frame which is not acceptable.
