Featuring durable metal construction, sound and light dampening baffles, and an easy-to-install expandable frame, this BPI-listed product enhances indoor air quality and energy savings while fitting seamlessly into existing walls. Made in the USA and backed by a lifetime warranty, it’s the smart retrofit solution for modern homes. ## Description On average, we spend 90% of our time indoors, but indoor air quality is typically 2-5 times more polluted than outdoor air. Tamarack Return Air Pathways (RAPs, for short) are unique transfer vents designed to maintain adequate air flow between rooms and eliminate pressure imbalances. Our RAPs are a simple and inexpensive way to improve indoor air quality, relieve rooms of hot and cold spots, and reduce strain on AC systems. Most importantly, installing RAPs improves energy efficiency and provides homeowners with significant savings on both cooling and heating. The Return Air Pathway Register equalizes pressure in the home while dampening sound and light transmission. The kit is designed for easy installation in new and existing walls. This kit includes 2-white interior grilles, 1-interior baffle and a 2-piece galvanized frame. Review: Works as intended - My supply is on the same wall as the hinge of the door. For the last 11 years I've tried leaving the door cracked to allow for a return air path. I didn't know about this product. Needless to say both bedrooms were never that comfortable. Out of sheer frustration I went online to do research and found these. I was skeptical as in my mind it couldn't work because the return path is still right next to the supply vent. So I called the HVAC company to come out and put returns in both bedrooms. He said the easiest and cheapest would be to install, you guessed it, these. Maybe not these in particular but a return air path which is essentially what these are. So I didn't even wait for his quote and I installed them myself. Watched the video on tamarack website and YouTube and noticed today that the rooms are much more comfortable. Normally the spare bedroom with the computer would get hot. Today I was on it and felt comfortable. That hasn't happened in 11 years. Cost me $200 for these and new oscillating tool blades plus my time. Well worth it. I bought a manometer to test the pressure, ok it cost me $240, and I'm getting the same pressure in the supply and out the rap. Well worth it for me. It fits my old brick construction home with my 2x4 walls that have plaster and sheet rock not lathe. Yes I was surprised too. Pleasantly surprised. I had widened a door before so I new what I was getting into. I chose not to center the rap as I didn't want to cut a cripple. It fits perfectly between the cripple and stud. Review: Complete product - Product has everything I needed to complete my project. The noise blocking material also did a great job of blocking light. ## Features - QUALITY AIRFLOW – Save time, energy, and money with a Tamarack transfer grille.

The noise blocking material also did a great job of blocking light. ### ⭐⭐⭐ Affordable solution but can be difficult to install *by J***S on July 1, 2018* These is an affordable alternative to running a new return duct. I keep my office door closed all the time, and the air is definitely less stale after I installed on. It is a little difficult to install because it is not complete square. One of the three units I ordered was dented. I had to hammer it back into shape and struggled pulling the two pieces apart and then struggled to reassemble them in the wall. Also, the spacing between the holes on the grate is not large enough to clear the metal flanges. For each one, I had to drill through the sheet metal in order to screw the grate into the wall. ## Frequently Bought Together - Tamarack Technologies Return Air Pathways (14X8 Retrofit) - Tamarack TTi-RAPR12.4 RAPR 12" X 4" Wall Return Air Pathway - Retro Fit - Tamarack TTi-RAPR12.6 RAPR 12" X 6" Wall Return Air Pathway - Retro Fit white --- ## 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.kr/products/52294357-technologies-return-air-pathways-14x8-retrofit](https://www.desertcart.kr/products/52294357-technologies-return-air-pathways-14x8-retrofit) --- *Product available on Desertcart South Korea* *Store origin: KR* *Last updated: 2026-05-17*
