I tried to read the instructions to open the blades...ended up popping the blades out ...no worries their are you tube videos and the company that makes them is small but very responsive...honest and helpful ...I am talking txt messaging helpful with video links being shared for tutorial ....incredible folks work there. So don't use excessive force on the blades ...they move easy but move from underneath...once set it is hard to change them ...also don't screw them to the side ...you don't need to they are heavy and sit nicely on the slot ## Frequently Bought Together - BUILDMART - 48" Linear Slot Diffuser - (2 Slot) Double Slot - White Decorative Air Vent - Modern AC Vent Cover for Ceiling, Walls & Floors - Texas Buildmart - BUILDMART - 36" Linear Slot Diffuser - (2 Slot) Double Slot - White Decorative Aluminum Air Vent - Heating and Cooling Modern AC Vent Cover for Ceiling, Walls & Floors - Texas Buildmart - BUILDMART - 24" Linear Slot Diffuser - (2 Slot) Double Slot - White Decorative Air Vent - Modern AC Vent Cover for Ceiling, Walls & Floors - Texas Buildmart --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.co.uk/products/547174378-48-2-slot-linear-slot-diffuser](https://www.desertcart.co.uk/products/547174378-48-2-slot-linear-slot-diffuser) --- *Product available on Desertcart Great Britain* *Store origin: GB* *Last updated: 2026-04-22*
