The Flow Cap Mount is a precision-machined aluminum adapter that mounts a Flow Cap securely to the back of your RGB Critter setup.

In the box: the mount itself, with both M4 x 3 set screws already fitted, the PTFE shim, the stainless connecting screw, and both Allen keys, 2 mm and 4 mm.

Full details and specs Show less

This aircraft-grade component twists directly onto the rear threads of the RGB Critter BT or the Saber Hilt Extension, adding 45mm of length while creating a rugged, weighted rear mounting point for spinning and performance flow.

The rear of the mount features a raised locking profile that mates with the internal ribs of the Flow Cap, holding it firmly in place without clips, holes, or extra hardware. The Flow Cap pushes on and pulls off. It does not twist.

For added momentum and balance, the mount can be paired with the optional Contact Saber Weight. The stainless steel weight has no threads of its own: it slides into the mount's bore, and the mount's two preinstalled M4 x 3 set screws tighten down into a machined groove in the weight to lock it in place. The 2mm Allen key for those set screws is in the box.

Fully assembled with the weight and a Flow Cap, this setup adds significant counterweight to the rear of the saber, increasing centrifugal force for smoother spins, better control, and improved handling during contact-style movement.

It also suits alternate builds, including Flow Chucks and RGB Critter juggling club configurations.


Includes

  • Flow Cap Mount (aircraft-grade aluminum), with two O-rings fitted
  • 2x M4 x 3 stainless set screws, already fitted to the mount
  • 2mm Allen key, for the two set screws
  • Flow Cap Counterweight System Screw, the stainless connecting screw
  • Flow Cap Counterweight System Shim (PTFE)
  • 4mm Allen key, for the connecting screw

Contact Saber Weight and Flow Cap sold separately. To get the mount and the weight together, see the Flow Cap Counterweight System.


Locking it to the Saber Hilt Extension

The connecting screw, the PTFE shim and the 4mm Allen key that drives them are all in the box, and together they let you semi-permanently join the Flow Cap Mount to the Saber Hilt Extension.

The shim seats at the joint between the two parts, and the screw passes through the front of the mount into the hilt extension. Once it is tightened, the mount and the hilt extension will not unthread, rotate or work loose no matter how hard you spin. They stay joined until you take the screw back out with the 4mm Allen key.

Installing it is optional. Leave the screw out if you want to keep breaking the build down by hand, and put it in if you want a fixed, rattle-free rear end for contact and high-speed work.
