KS3 Cobra Bag - Core Only

The Kewlus Cobra Bag is the world's first modular cobra bag capable of customisations, add-ons, upgrades and DIY integrations. Components just click together, so it's fast and easy to put up and to put away. It is the only cobra bag that is easily portable. Every component has been designed using 3D software and manufactured using advanced materials for ultimate strength and reliability. Most importantly each component can be individually upgraded when a new version of it is released. This cobra bag kit is part of the new type of modular training system that will continue to evolve, so your investment is well founded.

The Core Only Cobra Bag

The Core Only Cobra Bag is meant for those who wish to save money by making their own baseboard. It's also for those who can bolt/screw down the Multi Base to the floor, thus not needing the Platform Paddles or Sandbags. The Core Only Cobra Bag can also be used with Suction Cups on painted floors (such as a painted garage floor).

If you want a complete, free standing cobra bag that includes the platform (Platform Paddles and Sandbags), please check out the KS3 Cobra Bag - Free Standing.

The KS3 Spring

The KS3 Spring is the third generation Kewlus Cobra Bag Spring. It is made from a special type of steel, designed to withstand heavy punishment without breaking. It comes with alloy connectors, each having two adjustment points. The KS3 Spring can be inserted directly into the Multi Base, giving you an alternative shortened version of the cobra bag (minimum height just over 3 foot) - ideal for small kids as young as 2!

Important: Before using the KS3 Spring, please read the KS3 Spring Maintenance Guide.

The Multi Base

The Core Kit includes the amazing Kewlus Multi Base which can be used to support the cobra bag in a number of different ways:

• Screwed into the floor such as a concrete floor in a garage or a wooden outdoor deck using 8 suitable screws;
• Used with Platform Paddles (optional add-on) and weighed down with sandbags (optional add-on) and/or other weights;
• Screwed to a DIY baseboard (not included)  and weighed down with sandbags (optional add-on) and/or other weights;
• Used with 2 suction cup handles (optional add-on) on a smoothly painted garage floor (see details below).

The Multi Base comes with a stainless steel hose clamp. Once the Click Mast is inserted into the Base it's important to tighten the clamp around the base collar as much as possible.

What's Included in the Core Kit

The Cobra Bag Core Kit includes the following:

• Kewlus Spring (KS3) is the 3rd generation Kewlus spring that fits onto the Click Bars and is also compatible with 3/4 inch pipes for DIY setups.
• Genuine leather cobra ball, designed to fit perfectly onto the Kewlus Cobra Ball Adapter and made to outlast all other types of balls;
• Kewlus Cobra Ball Adapter (V2), designed to be used with most speed balls but is the perfect match for the Kewlus Cobra Ball. One unique feature that's not found on other cobra bags is it allows the user to extend the length of the top section, thus increasing the reach of the cobra bag;
• 2 x Kewlus Click Bars - one goes above the spring and one below. These are made from light, yet strong aluminium which will not rust, with dual push buttons at each end. They are a key part of the modular click-and-go system;
• Kewlus Click Mast (V2) - designed to simply click into the Multi Base for quick and easy removal and storage of the cobra bag. Made out of strong aluminium it will never rust. The bottom Click Bar simply slips into this mast and clicks in place at the desired height, giving you a height adjustable cobra bag suitable for both kids as young as 8 and adults as tall as 6 foot;
• Kewlus Multi Base - super strong, minimalistic base made from composite fibre. It's designed to be used in multiple ways, such as with a baseboard, with Platform Paddles, with Suction Cup Handles or simply bolted to the floor. It comes with a stainless steel clamp for the collar to lock the mast in place for the ultimate rigidity.

The idea is to be able to swap as well as reutilise components as new add-ons are released. Check out my Youtube channel and stay tuned for more that is to come!

Height Range

The height range of the cobra bag is roughly 4'8 (143 cm) - 5'7 (171 cm) from the floor to the top of the bag when using a 1.5 inch baseboard. If you wish to increase the height, consider making a 5-inch tall "Stubby" baseboard (see details and video: https://kewlus.com/blogs/diy/how-to-make-baseboard-cobra-bag).

Convertible To Short Form

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

Optional Accessories & Add-Ons

Check out the Accessories section for optional accessories and add-ons such as:

• Max Speed Cobra Ball & Adapter Combo - switch to a lighter and faster ball mid-session;
• Genuine Leather Boxing Gloves - grab a pair of these genuine leather boxing gloves to get the most from your cobra bag training sessions;
• Hand Wraps - use a pair of handwraps to absorb the sweat and protect not just your hands, but your gloves as well.
• Suction Cups (Limited/Varied Usage) - these come as a pair and can be used on painted concrete flooring, such as in a garage to hold down the Base as a possible alternative to the Platform Paddles. They can be also used for mounting the shortened version of the cobra bag on a vertical surface. Please note that these suctions cups do not work on all surfaces, and even on smooth tiles are likely to dislodge with heavy punches. I cannot guarantee that they will work on the surface that you choose. Failure to stick to your floor or wall surface does not qualify for a refund. See the Suction Cups product page for set-up instructions and a demonstration video.
