The Wolfram Spreader Bar but with a twist! See the Original Wolfram Spreader Bar Here
 
This upgrade has disk attachments on each end which can lock into the included set of Slide-Locking Cuffs for a tight and elegant lock.
 
*****PLEASE READ*****
This product only comes in a set of Spreader Bar + Cuffs because a typical set of Slide Lock Cuffs link together with a mechanism that has a left and a right side. The attachments on this spreader bar are only the right side of the mecanism so both cuffs must be left sides. So this set of Slide Locking Cuffs ONLY LOCK ONTO THE BAR AND NOT TO EACH OTHER LIKE A TYPICAL SET. 
 
They do have D rings though so they can be connected with a carabiner.
 
If you would like a set that links together as well but don't want to purchase a whole separate set, there is an option to purchase a single cuff that is the compliment to one of the set cuffs included so you would have a set that links together where one cuff can be switched out to links to the bar without having to purchase 2 separate sets.
 
The best thing to happen to cuffs since leather, is carbon fiber. 
 
In true House Of Wolfram fashion, we have found a way to make a classic device both better, and much much prettier.
 
The Wolfram Spreader Bar is our take on the devious and timeless tool of torment. Made of industrial strength roll wrapped polymer stabilized carbon fiber, this material is stronger and lighter than steel and reinforcing it with black anodized aluminum fittings and stainless steel shackles.
Unlike other spreader bars that are heavy, cumbersome to use, and difficult to carry around, our spreader bar solves all these problems and adds a unique surprise.
 
-Portable
The Wolfram Spreader bar was designed for portability and can easily fit in any backpack or toy bag collapsing down to 16" with just the turn of the collet and a push.
 
-Strong
Carbon fiber is extremely strong. Nearly 4 times the tensile strength of steel per mass. Feel free to play heavy because you're going to have a hard time breaking this bad boy.
 
-Light
At less than half a pound, The Wolfram Spreader Bar is incredibly light and comfortable for something that strong which makes for easier play and even easier portability.
 
-Easy to Use
No buttons, disassembly, set increments, or screws required. All you need to do is hand loosen the friction collet and the spreader bar telescopes out. Tighten the collet at your desired length and that's all there is to it.
 
-Conductive
If you want to get really devious. Carbon fiber is a very conductive material and since all the fittings are metal, just touch it to a violet wand and watch the sparks fly.
