When working with 40NB tubing, getting the right fit matters.
Our 40NB Tube End Caps are engineered to provide a precise, secure fit, sealing exposed ends to protect your frame from moisture, dirt, and internal corrosion.
These caps don’t just protect—they complete the look. Featuring the Funky Monkey Bars logo, they add a clean, professional finish.
They also improve safety by covering exposed tube edges, making your setup safer for active use while maintaining the durability you expect from a premium product.
