XL Prime (KS3) Core Kit

The XL Prime Core kit, just like the O₃ combines the top end of the most advanced modular components to date to give you the most advanced setup but with the option to use your own custom platform. You could either screw it down to the floor or make a solid DIY base by gluing a number of MDF boards together. This kit features the XL Base Connector, a taller connector that integrates a 50mm diameter shaft at the top to offering the option to place one or two Olympic weight plates over the top of the sandbags. The extended height and shape of the XL Connector further adds base/mast stability and rigidity, as well as extra height. Combined with the world's most advanced Prime (KS3) Spring, this kit, just like the O₃ delivers the performance and reliability sought by boxing gyms and professional boxers.

What's Included:

• The Prime (KS3) Spring: Third generation spring made from the unique formulation of metals for the ultimate performance and longevity. No other spring comes even close.
• Prime Target: Durable genuine leather ball designed for ultimate performance and durability. It's the perfect balance between speed and power.
• Target Adapter: Extendable length for increased reach, designed and engineered to allow flexibility at the rim for cupping the ball while maintaining top section rigidity and rebound speed. The adapter and Kewlus balls have been designed in unison to fit perfectly together for optimum performance.
• Red Bar: Used in the top section to for increased speed, the Red Bar has a slight level of flexibility, adding to the overall rebound performance of the Kewlus.
• Click Bar: Lightweight, rust-free aluminium bar used in the bottom section (below the spring) for overall height adjustment.
• Stainless Steel Mast: Made for the ultimate strength and reliability, the SS Mast is suitable for public gyms and extremely heavy use of the Kewlus.
• XL Base Connector: Made from composite fibre for the ultimate strength and rigidity, the XL version of the Base Connector adds extra height and rigidity.
• Pair of Sandbags: Designed for stability when filled with sand, especially if using wet sand (make sure to use a garbage bag as a liner). These will also act as a support for the optional Olympic weight plates, absorbing shock and improving performance.

Height Range:

5'1" to 6'0" (155 cm to 183 cm). Setting the correct height for you is important. The top of the ball should be just above your chin. Watch boxing coach Paul Briggs (former highly ranked contender in the light heavyweight division) explain how to set the correct height:

Convertible to a Short Form

The Kewlus is convertible to a short form for children or for suspending it upside down. This is a unique capability that is only possible with the modular Kewlus system. With the Kewlus it's super quick and easy to set it up for your child. Just plug the Prime (KS3) spring directly into the XL Base Connector and tighten the steel clamp. With Kewlus you can get your children learning hand-eye coordination and boxing skills as early as you would like them to.

This ability to transform the cobra bag to a short form also allows it to be suspended upside down from an overhead structure such as a support beam. You can then adjust the length by either using the Click Bar for extra length or the Red Bar for shorter length.

Correct Assembly:

Assembly for the XL Prime Core Kit is identical to the O3 kit assembly, but instead of attaching the Standard Base Connector to the OctaBase, you will be screwing it down to your own platform.
