The SoloSider is a high quality tool, used to hang 5/16 fiber-cement siding and 3/8 to 7/16 LP Smartside using the correct overlap. It can be adjusted for different size overlaps (3/4in. to 1 3/4in.) with a simple push and twist, no screws or nuts to worry about. It will move the plank up and down in 1/16 increments without having to remove it from the hangers. It will not rip the paper or house wrap. It will not mark the siding.
