The Block has a knob that allows you to “lock” the Standing Pole in the desired position. To extend the canopy out, simply loosen the black knob, adjust the Sliding Pole to the desired position, and tighten the knob.
The Block is not to be confused with the Slider, these are two different parts. Each unit has both a Block and a Slider. Have a question? Connect with us at firstname.lastname@example.org
