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.. Review: Good product - 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. ## Features - Reduce Condensation, Damp & Mould By Providing Air Flow 1 Single White Trickle Vent - Each Easy To Fit Vent Include Inside Part, Outside Part, End Caps & Screws - Suitable for uPVC Double Glazed, Timber, Aluminium Windows & Doors Heavy Duty Can Be Used To Replace Existing Vents - 407mm Length Providing An Impressive 3728 mm2 Air Flow Tested In Accordance With BS EN 13141-1:2004 - External Dimension: 407 x 17 x 24mm Internal Dimension: 407 x 17 x 14mm ## Technical Specifications | Specification | Value | |---------------|-------| | Manufacturer | Draak | | Part Number | MJ 4000 | | Product Dimensions | 40.59 x 3.91 x 1.6 cm; 81.65 g | | Item model number | MJ 4000 | | Size | 407mm | | Colour | White | | Item Package Quantity | 1 | | Batteries included? | No | | Batteries Required? | No | | Item Weight | 81.6 g | ## Images ![407 Trickle Vent - Image 1](https://m.media-amazon.com/images/I/51Y4D53T9tL.jpg) ![407 Trickle Vent - Image 2](https://m.media-amazon.com/images/I/61iOtDSYJRL.jpg) ![407 Trickle Vent - Image 3](https://m.media-amazon.com/images/I/61RRTn7zArL.jpg) ## Available Options This product comes in different **Size, Item Package Quantity** options. ## Questions & Answers **Q: How do you fit them because i'm totally useless at diy?** A: Hi. The part with the lift up flap goes on the inside of the window frame and the larger grill part goes on the outside of the frame. I drilled a series of holes along the line of where I fitted the vent to provide the airflow using a very sharp new drill. **Q: Do these go on the window or above on the frame?** A: They can go on either, but the frame is best **Q: Does it come with a packaging which confirms that 407mm length providing an impressive 3728 mm2 air flow tested in accordance with bs en 13141-1:2004** A: Yes **Q: 1. Should the flap open up or downwards? 2. How often/long should they be open for to stop the condensation/damp please?** A: Flap hinge should be at the top and the flap open upwards. Mine are left open permanently and effectiveness is dependent on size of room, size of window and the temperature / humidity of the environment. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Great value, easy fit, direct replacement vent! *by J***S on 12 September 2023* I fitted three of thes to replace existing ones that snapped due to aged plastic.
