Duncan Cab Rear Window Gas Strut 250N - 290mm Length with 90mm Ram Extension SKU: QT1332

A failing window gas strut means fighting with a heavy rear window that won't stay open when you need ventilation or slams shut unexpectedly during operation. When these struts lose pressure, your window becomes heavy and hard to operate, creating unpredictable and hazardous conditions. This 250N Duncan cab replacement restores smooth, controlled window operation so you can work safely and comfortably.

Why Proper Force Rating Matters

• 250N force rating is precisely engineered for Duncan cab rear window weight and balance
• Using incorrect Newton ratings can result in glass breakage, door damage, or serious injury
• 290mm length with 90mm ram extension matches factory specifications exactly
• Heavy-duty sealed construction maintains consistent pressure through temperature extremes

Always verify the Newton rating of your existing gas strut before ordering a replacement. Duncan cab systems require this specific force rating to operate safely - too weak and the window won't stay open, too strong and you risk damaging the window frame or glass. S&H Parts has been helping operators find the right strut specifications since 1969.
