The Kit 20 poles extend from 6′ 9″ to 20 feet. The spring loaded plunger called the jack screws onto the end of the pole and adds a foot of reach. This product can actually be used in areas with a ceiling height up to 21 feet. The poles can be placed 8 to 10 feet apart. If there is any significant air movement that pushes the plastic you will need to pull them in closer together, anywhere from 4 to 8 feet. If the poles are placed closely together you may need two or more people to attach them to the plastic and raise them into place. The GripDiskTM slide stoppers should always be used especially on hard surfaces. Two GripDiskTM slide stoppers come in every Kit 20 package.
2 20 foot extension poles, 2 spring-loaded jacks, 2 grip disks, 2 tethers
