Description
A cracked-open window is the cheapest way to fight condensation, but a window flapping on its stay at 3am is nobody’s idea of a holiday. This strap holds it steady at the gap you choose, from a small vent to wide open.
Features
- 7 opening positions along the strap
- Tool-free fitting: slip it on, no drilling and no screws
- Smooth, rounded edges with no sharp corners to catch frames or fingers
- Slim 4 mm profile that sits neatly against the frame
- Lightweight, so it won’t rattle the window about
- Quick to move or remove at any time
- Built for caravan life: copes with sun and damp
- Designed and made in Hull
How it works
- Slip the eye at the narrow end over the window handle arm.
- Pick the bar that gives the opening you want, then drop the ladder section over the two raised tabs on the frame bracket. One tab goes through each hole and the bar sits in the gap between them.
- To change the opening, lift the strap off and move it one bar along.

FAQs
How many do I need?
Two per window is best, one each side.
Will it fit my caravan windows?
It fits windows with a two-tab frame bracket and a flat handle arm. Check the measurements above, or send a photo.
Can I leave it on while towing?
No. Take it off and close the window properly before you set off.
Will it stop condensation?
It lets you keep a small, steady vent gap, which helps. For bad damp, see my guide to fixing damp in a caravan.
