KS3 Kewlus Core Kit

The Kewlus Modular Cobra Bag is the world's first modular cobra bag capable of customisations, add-ons, upgrades and DIY integrations. The KS3 Kewlus Core Kit is perfect for those looking to make their own custom base (or screw it down to the floor) for optimum performance.

Kit Suitability

This kit is best suited for those who would like to get maximum performance from the cobra bag by making a DIY base or screwing the Base Connector to the floor.

ATTENTION: It is critical to assemble the ball & adapter correctly. Please ensure you read the instructions fully before use. Failure to assemble correctly may void your warranty.

What's Included:

• KS3 Spring: Third generation spring with multiple setup options.
• Max Power Leather Cobra Bag Ball: Durable leather ball for powerful punches.
• Cobra Ball Adapter (V2): Extendable length for increased reach.
• 2 x Click Bars: Lightweight, rust-free aluminum bars.
• Click Mast (V2): Height-adjustable and easy to store.
• Base Connector: Versatile base connector made from composite fiber.
• Pair of Sandbags: The two bags add 90 pounds of weight when filled with sand.

Custom Base DIY:

The Core Kit does NOT include any base, giving you the option to make your own heavy duty, custom base. The best and easiest way to make a base is to simply glue together two or more 2ft x 2ft MDF boards. Usually one MDF board is not thick enough, so gluing together multiple boards provides the thickness needed for using long screws. I recommend a thickness of at least 1.5 inches, but with more boards glued together you will also gain an advantage of extra height as well as extra weight.

The recommended minimum weight for the base is 90 pounds (one pair of Sandbags), however adding a second pair of sandbags on top or an Olympic Sleeve with a weight plate will improve performance.

Height Range:

The height range of the cobra bag is roughly 4'8" (143 cm) to 5'7" (171 cm) from the floor to the top of the bag. This can be increased to suit taller fighters by making the base taller (gluing together more boards in the making of the base).

Convertible to Short Form:

The KS3 Cobra Bag can be converted to a shortened form, making the height range roughly 3'3" (100 cm) to 3'7" (110 cm). This form is ideal for smaller children or for mounting upside-down from the ceiling or horizontally on a wall.

Optional Add-Ons:

• Additional Pair of Kewlus Sandbags (V2): For extra weight and improved performance.
• Olympic Weight Plate Sleeve: Allows the use of one or two Olympic weight plates for added stability.
• Red Bar: Increases the speed of the cobra bag.
• Max Speed Ball & Adapter Combo: Enhance speed training with a lighter and faster ball and adapter combo.
• Cobra Bag Replacement Bladder: Backup replacement bladder for future use.

Product Features:

• High Performance: Engineered for speed, power, and durability.
• Modular Design: Customizable components for a tailored training experience.
• Used by Champions: Trusted by world champion boxers for elite training.
