A hinged leg is joined to the base leg proximate an end of the base leg for extending generally downwards towards the floor. The hinged leg includes a second foot for resting on the floor. An extension tube extends upwardly from the base leg where a length of the extension tube above the base leg is adjustable. A locking mechanism locks the extension tube at an adjusted length above the base leg. A first sash support is rotatably joined at a first position on the extension tube for rotating about the extension tube from a first position to a second position for supporting the tilt-in sash in a generally horizontal position.

    • A curl spring sash shoe cassette improves upon the suggestions of U.S. Pat. Nos. 5,353,548 and 5,463,793 by providing a mounting bracket that holds an uncurled length of the curl spring and is securely mounted on top of the shoe cassette to maintain an assembly of the shoe body, the curl spring, and the mount during shipment to a window manufacturer. The mount can receive two mounting screws to resist torque caused by curl springs and sash weight. The shoe is also improved to facilitate removal and reinsertion of sash pins into the tilt lock cams of the shoes and ensure that shoe body halves do not rotate relative to each other when sash tilting splays the body halves apart to lock them in a shoe channel.
