Malco’s “The Sider” helps you measure and mark pieces of vinyl siding quickly and accurately. Made from 18 gauge stainless steel, the Sider has precisely spaced holes staggered vertically every 1/8″. To draw or score perfect horizontal lines, stick a pencil or knife blade into a hole and slide the tool along the siding.
Malco sells five different varieties of the Sider to work with most siding styles: the 4″ double, the 5″ double, the 4-1/2″ Dutchlap, the 5″ Dutchlap, and the 3″ triple. Any of these versions of the Sider will run you somewhere between $11 and $21 before shipping or tax.
