• The Jamb Spreader® and Curtain Spreader are so innovative that they were each granted a patent! (U.S. Patent #'s 5,224,298 & 6,176,293).
• The Jamb Spreader works with most brands of quality double-hung windows utilizing flexible vinyl jamb liners ("compression jambs") and incorporating a tilt feature for easier cleaning of the outside glass surface.
• The new Curtain Spreader keeps fabric window treatments out of the way for easier cleaning. It works with all brands and types of double-hung windows.

• Spreads curtains to ease cleaning for all types of tilt double-hung windows. Provides a working range of 30" to 50".
• Lightweight, at only 8 ounces! Won't harm even sheer curtains. Just clip tool to curtains, then extend and twist-lock to proper length!

The Jamb Spreader® Window Tilting Aid
Which Jamb Spreader size(s) do you need? Just measure the width of your narrowest and widest window sash (same as the "jamb-to-jamb" measurement), then check the specs below to see which tool size will match the range of windows in your home. With three tool sizes and two helpful accessories, we can make tilting easier for almost any compression-jamb window, big or small!

• Accommodates the most common window sizes (may not work with very narrow or very wide units).
• Can be used with extension accessory (#JS-EXTN) to work with glass widths up to 40" (42.75" jamb-to-jamb).

Extension Accessory: #JS-EXTN  $8.95 each + $5.95 S&H (ships free with tool)

• This accessory extends the range of The Jamb Spreader without the full cost of a second, larger tool.
• Extends range of Standard tool to work with glass widths up to 40" (42.75" jamb-to-jamb).
• Extends range of Junior tool to work with glass widths up to 36" (38.75" jamb-to-jamb).

An accessory for use with all Jamb Spreader sizes, our End Adapters mount to both ends of the tool. They effectively broaden the tool’s ends from a width of 1½" to 3", allowing it to contact & compress the jamb liners' full width, rather than just the front or back tracks. This full-width compression of the jamb further eases tilting of the top sash on windows that are especially tight or have deep jamb profiles. Kit includes two pre-drilled adapter pieces, instructions, and screws for attachment to tool. Note: adapters lengthen collapsed tool by about ¾".
