Telescoping Weld-Together Rails

Create posts of varying lengths. To telescope rails, slide one length of rail into the next larger size rail (for example, a 1 _3/4" height rail fits into a 2" height rail and a _3/4" dia. rail fits into a 1" dia. rail). Weld the rails together at the desired length to create strong structures. These rails are not compatible with weld-together framing and fittings.
