LOCUS GEAR Locus Gear DPTE Carbon: 84g (including stuff sack) This product allows you to split a trekking pole, such as the CP3, into two. It is in beautiful condition with no scratches or dirt. Quoted from the website below: This is an optional part for setting up Khufu (クフ) and Hapi (ハピ) series shelters in an "A-frame" configuration using two trekking poles (adjustable to 130cm or longer) instead of a single pole. DPTE (Dual Pole Tip Extender), or DPTE (ディー・ピー・ティー・イー) for short. While the ease of setup is the biggest feature of a single-pole shelter, having the pole in the center also has the disadvantage of compromising the inherent space. By using DPTE, you can free yourself from the hassle of a center pole and make better use of the ample space that the Khufu series shelters offer. While setup may take slightly more effort than a single-pole setup, you will surely be satisfied with the living space after setup. DPTE can also be used with inner shelters. In that case, the inner shelter will hang down as it is set up from the apex inside the tent.
