HOW 001 ORDER? <br />Important! Accurate Measurements <br />For Accurate Ordering <br />Since all Marvin windows are made to order, it's <br />extremely important to obtain the proper <br />measurements before ordering a Tilt Pac'. Consult <br />-a Marvin dealer or professional window installer. <br />Your first measurement <br />should be the width of <br />the sash opening. Place <br />yourtape measure <br />againstthe inside of the <br />jamband measure <br />across to the inside of <br />the opposite jamb (see <br />drawingand photo). <br />Lower the top sash a <br />few inches, and mea- <br />sure from the spot <br />where the top sash <br />touches the header to <br />where the exterior <br />side of the bottom <br />sash touches the sill <br />when closed. This is <br />the sash opening <br />height. Ifyourwindow <br />has wooden blocks <br />holding the top sash in <br />place, remove them. <br />E <br />Top View ........ <br />Screen Opening Width <br />Width of <br />Sash Opening <br />G <br />Sash <br />Opening <br />Height <br />0 <br />Screen <br />Opening <br />Height <br />0 Sill Angle <br />Measure the angle of <br />the sill. A standard sill <br />angle for Marvin's Tilt <br />Pac is 14 degrees. On <br />wood Tilt Pacs, nearly <br />any angle is available, <br />but you must tell us <br />which angle you need. <br />You can get a <br />convenient, palm - <br />sized sill angle finder <br />at most stores where <br />tools are sold. <br />Side View <br />If you would like a screen with your Tilt Pac, two <br />screen measurements are needed. Important: <br />Make these measurements separately, after you <br />are certain all other measurements are correct! <br />First, measure the distance across your <br />exterior' casing, from inside edge to inside <br />edge. This is your total screen opening width. <br />Now measure from the lower edge of the top <br />casing down to where the screen will rest on <br />the sill. This is your total screen opening height. <br />
