Review: Great for Ventilation Needs - We purchased these for our sunroom for adequate ventilation from the soffit. (This acts sort of like a ridge vent in that respect.) The 4" rounds fit into a universal mount for vinyl siding ( you just need to have a 4" round hole saw to cut and you are golden.) We caulked the louvres into place, and there is a bit of room to caulk from the inside of the wall, too. Very sturdy louvers. Screen is well made. Great USA made product. We spray- painted the white louver with RustOleum's Roofing Touch Up Spray ( in Wicker to match our siding)- which is made just for exterior uses such as this. It turned out exactly as hoped. Recommended product. Review: They work fine. However, make sure you do your math first regarding attic ventilation needs. - They are fine. I urge anyone buying soffits to first measure the sq. ft. area of your attic and ensure you have calculated the intake/exhaust needs of your attic space. I have plenty of ridge vent but virtually zero intake soffit vents. At first, I thought a single one of these for each rafter space would suffice. However, for my 2,000 sq. ft. attic space, these did not generate enough NFA (net free airflow). Now, I had to rip them all out and install a 6in wide continuous soffit vent. Save yourself time and money and do you research/calculations BEFORE buying soffits. ## Features - Pack Of 4 - 4-Inch White Aluminum Round Insect Proof Mini Louvers With Screen - Overall Size 4.625-Inch Fits 4-Inch Hole Diameter - 3.5 Square Inch Free Area ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B000BQM5EC | | Best Sellers Rank | #553,646 in Tools & Home Improvement ( See Top 100 in Tools & Home Improvement ) #88 in Exterior Louver Window Shutters | | Brand | Maurice Franklin Louver | | Brand Name | Maurice Franklin Louver | | Color | White | | Customer Reviews | 4.7 out of 5 stars 431 Reviews | | Global Trade Identification Number | 00738312024055 | | Included Components | Household Item | | Item Type Name | Maurice Franklin Louver RLW-100 4, 4-Inch Mini Round Aluminum Insect Proof Mini Louvers With Screen, White (Pack of 4) | | Item Weight | 4.16 ounces | | Manufacturer | Maurice Franklin Louver | | Manufacturer Part Number | RLW-100 4 | | Material | Aluminum | | Material Type | Aluminum | | Model Number | Maurice Franklin Louver - RLW-100 4 | | Number of Pieces | 4 | | Style | Modern | | Style Name | Modern | | UPC | 738312024055 | | Unit Count | 1 Count | ## Product Details - **Brand:** Maurice Franklin Louver - **Color:** White - **Global Trade Identification Number:** 00738312024055 - **Is Electric:** No - **Item Weight:** 0.26 Pounds - **Material:** Aluminum - **Number of Pieces:** 4 - **Style:** Modern - **UPC:** 738312024055 - **Unit Count:** 1.0 Count ## Images ![RLW-100 4, 4-Inch Mini Round Aluminum Insect Proof Mini Louvers With Screen, White (Pack of 4) - Image 1](https://m.media-amazon.com/images/I/71dwArGq9WL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Great for Ventilation Needs *by R***D on January 21, 2020* We purchased these for our sunroom for adequate ventilation from the soffit.

They have build in (metal) mesh screens to keep bugs, etc. out which is a great design! Much better than the products offered at the local big box stores and a better price as well. Overall, these are a fantastic item at a great price. If you have venting needs that require a 4" louver design, these are for you! Great customer service and super fast shipping as well. ## Frequently Bought Together - Maurice Franklin Louver RLW-100 4, 4-Inch Mini Round Aluminum Insect Proof Mini Louvers With Screen, White (Pack of 4) - JIECHENG Bi-Metal 4 inch Hole Saw with Arbor Mandrel for Deeper Cutting of Wood,Cornhole Boards,Drywall,Plasterboard,Plywood,Steel,Aluminium,Brass,Copper,Zinc,Tin,102mm - Hole Saw 4” (102mm) for Wood, HSS Bi-Metal Hole Cutter with Pilot Drill Bit for Plastic, Plastboard, Cornhole, Ceiling and Drywall --- ## 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.pt/products/3786187-rlw-100-4-4-inch-mini-round-aluminum-insect-proof](https://www.desertcart.pt/products/3786187-rlw-100-4-4-inch-mini-round-aluminum-insect-proof) --- *Product available on Desertcart Portugal* *Store origin: PT* *Last updated: 2026-09-08*
