Dometic Seitz S4 Top-Hung Window | Built-In Blind & Fly Screen

A complete opening window for a van or motorhome wall: frame, glazing, blackout blind and fly screen in one unit. Dometic describe the Seitz S4 as proven millions of times in motorhomes and caravans.

• Top-hung opening on telescopic hinges, so you can prop it open to ventilate
• Built-in darkening roller blind and fly screen in the inner frame
• Security locking that stops it being opened from outside
• Insulating construction that Dometic compare with house-building standards
• Four sizes: 900 × 450, 1100 × 450, 1200 × 500 and 1000 × 600mm

Choosing a size

S4 sizes are the size of the hole you cut in the wall. The outer frame is about 45mm wider and 33mm taller than the cut-out, so allow for that around ribs, panels and furniture.

Wall thickness

The window is ready to fit a 26mm wall. Thinner walls, such as a bare van panel, need a timber frame or spacer to bring them up to thickness, and the maximum is 53mm. Cutting a van's body panel is permanent, so if you're unsure about sizing or the frame, ask us before ordering or use an experienced installer.
