407 Trickle Vent

I fitted three of thes to replace existing ones that snapped due to aged plastic. There was no rear protective mesh to stop bugs, but that was easy and cheap to fix, and they look great. Overall happy with these items and will buy again, when my other old window vents fail..

Good product that does what it says on the tin. Is a bit flimsy but once attached to the window, it works perfectly fine. Take care when thinking about where to place it on your window frame. It definitely helped watching a YouTube tutorial beforehand as the supplied instructions are pretty vague. Provides enough fresh air in conjunction with an extractor fan to clear condensation from our bathroom window after the shower has been on in winter.

Great, easy fix

Old trickle vents were falling apart so ordered these on recommendation from a neighbour. Fitted the previous holes perfectly and look better. I used the previous fasteners though as the supplied screws had a smaller diameter. Order could have been improved if the inside and outside could be ordered separately as I only required the outside part. Self tapping screws would also be better than the screws provided. But apart from that I’m very happy with the purchase and have ordered more to change all the trickle vents on my windows.

Good quality, slim design, internal hood seems to be slightly yellow, external is definitely white though. Still happy with product

It was basically ok but made of cheap, thin-ish plastic, meaning it bends too easily. When I screwed the outer unit to the patio door (to replace a broken one), the unit bent a little in the middle leaving a part of the door vent holes exposed in the middle. Granted that these may have been cut in the door a little too big, but nonetheless, I didnt expect the vent to bend as much. I was able to screw (could have used PVC glue but didnt want problems removing it in the future) in a bit of thin plastic (cut to size) at the point where it bent, to push it back up again (i.e. straighten it). Additionally, there is no mesh/gauze to stop insects like the previous one. Granted the previous one was more up-market and likely more expensive but couldnt find a direct replacement. I sorted this problem out by using some fine mesh I purchased for covering plants. (This was also white so blended in nicely).

Is not universally usable.

This trickle vent makes a big difference in the circulation of air in the room, the musty smell has disappeared. We'll have to wait and see if stays the same in the winter months. But so far so good! Installation is a bit fiddly but can be done.

Franchement, ils vont bien. Facile à installer. Fermeture du système plutôt bien pensé

Die Lüftungsschlitze sind mit ein wenig handwerklichem Geschick leicht anzubringen und bringen eine geringe Menge Frischluft in den Raum.

Va genial. Siempre tenía mucha humedad en el baño y en época de frío no podía abrir la ventana cuando me duchaba porque es muy grande y me congelaba. Ahora puedo ducharme sin problemas y parte de la condensación se va por ahí.

Quick and easy. A+

Achetées pour remplacer celles existantes fragilisées par le temps. Pose en extérieur sur bois. Pas compliqué à installer mais une notice m’aurait facilité la tâche. Ceci étant le produit est correct. (qualité et aspect général) Chaque fente d’aération se compose de 2 pièces : • Un corps creux comportant 2 faces pleines, une face ouverte et une face grillagée, 2 vis de fixation et 2 caches • Un volet amovible avec 2 vis de fixation et 2 caches En l’absence donc de notice de montage et si cela peut aider certaines personnes, voici comment j’ai réalisé l’installation : 1- J’ai tout d’abord fixé le corps avec les 2 vis sur le plan de l’ouverture d’aération de la fenêtre de telle façon que le creux du corps recouvre entièrement cette ouverture et que sa face grillagée alors perpendiculaire au plan de ladite ouverture soit positionnée vers l’extérieur afin de la rendre aisément accessible pour le montage du volet. 2- J’ai ensuite fixé le volet sur le corps en l’emboîtant sur sa face grillagée afin qu’il la recouvre entièrement, les vis de fixation venant se visser dans les 2 trous carrés disposés de part et d’autre de la face grillagée du corps. Conseils : Ne pas trop serrer ces vis sous peine de cintrer le volet, le volet fermé devant resté plaqué à la face grillagée du corps. Ne pas monter préalablement le volet sur le corps du fait que les vis de fixation du volet vous empêcheraient d’engager les vis de fixation du corps dans les trous prévus à cet effet. 3- J’ai mis ensuite tous les caches de vis.
