the bucksteps will only comfortably allow you to get to about 15ft so if you start the first 4 feet with cheapy screw in steps you can save the good stuff for getting you to 18-20ft.
Or buy two sets of them as I did (allows me to get 25') and bungle cord one set to the stand and attach a strap to the other and sling it over the shoulder. Remove one entire set upon leaving. Works for me
