Sized specifically for thin twin-wall sheeting rather than a loose universal fit. - Tool-Free Installation: Slide the cap over the cut edge of the panel and press until seated. No drilling, screws, or adhesive required. Trim to length with a fine-tooth saw to match any panel width. - Keeps Flutes Clear: Open panel ends draw in rain, dust, and insects that collect inside the hollow channels. Capping both ends keeps the interior dry instead of clouding with trapped moisture, dirt, and algae. - Holds Up Outdoors Year-Round: Polycarbonate construction resists yellowing, cracking, and brittleness through summer heat and winter cold, so capped edges stay sealed across seasons. - Finishes Any Panel Project: Suitable for greenhouses, sunroom roofs, pergolas, gazebos, carports, porch covers, cold frames, chicken coops, and shed roofing. Pairs with H connectors to complete a full panel run. ## Technical Specifications | Specification | Value | |---------------|-------| | Asin | B0CX3MF9DQ | | Best Sellers Rank | #35,794 in Patio, Lawn & Garden (See Top 100 in Patio, Lawn & Garden) #3 in Greenhouse Flooring & Bases | | Brand Name | OWLHAUS | | Color | clear greenhouse panels clear roofing panels | | Cover Material | Polycarbonate (PC) | | Customer Reviews | 4.2 4.2 out of 5 stars (210) 4.2 out of 5 stars | | Door Style | refer to description | | Frame Material | Plastic | | Global Trade Identification Number | 04806538840387 | | Indoor Outdoor Usage | Outdoor | | Item Dimensions L X W X H | 24"L x 2.19"W x 2.2"H | | Item Highlight | Fits 4mm twin-wall panels; 2 ft length; caps open sheet ends against rain, dust, insects; greenhouse, sunroom, shed | | Item Type Name | greenhouse plastic sheeting polycarbonate panels | | Manufacturer | OWLHAUS | | Manufacturer Part Number | Greenhouses Polycarbonate Greenhouse | | Model Number | greenhouse panels polycarbonate | | Nominal Wall Thickness | 4 millimeters | | Number Of Items | 20 | | Size | 2ft | ## Product Details - **Color:** clear greenhouse panels clear roofing panels - **Brand:** OWLHAUS - **Product Dimensions:** 24"L x 2.19"W x 2.2"H - **Item Weight:** 0.61 Kilograms - **Cover Material:** Polycarbonate (PC) ## Images ![OWLHAUS Polycarbonate Greenhouse Panel Connectors, U Channel 4mm, 20 Pack - Image 1](https://m.media-amazon.com/images/I/318a7PkyXgL.jpg) ![OWLHAUS Polycarbonate Greenhouse Panel Connectors, U Channel 4mm, 20 Pack - Image 2](https://m.media-amazon.com/images/I/71vWYn72kDL.jpg) ![OWLHAUS Polycarbonate Greenhouse Panel Connectors, U Channel 4mm, 20 Pack - Image 3](https://m.media-amazon.com/images/I/61Sq9J+fU9L.jpg) ![OWLHAUS Polycarbonate Greenhouse Panel Connectors, U Channel 4mm, 20 Pack - Image 4](https://m.media-amazon.com/images/I/81iUp3aMjiL.jpg) ![OWLHAUS Polycarbonate Greenhouse Panel Connectors, U Channel 4mm, 20 Pack - Image 5](https://m.media-amazon.com/images/I/71CB68WatbL.jpg) ## Available Options This product comes in different **Item Shape** options. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Perfect for our needs *by on Reviewed in the United States May 6, 2025* These are perfect for the polycarbonate greenhouse panels that we purchased. I will be reviewing those later, if you want to go to that review to see which one's worked with these. I was a little concerned because the descriptions are hard to understand to know which ones will work. The ones that were linked to our polycarbonate panels we're not going to even ship until june, and we couldn't wait that long. So I took a gamble on these. And I'm glad I did. There are perfect our greenhouse roof is gorgeous. Everything's fit together perfectly. We did not have to cut any of these so I can't tell you how easy they are to cut. But functionally they are fantastic. They are great value for what you're getting. They seem nice and durable so far. I'm hoping they'll stand the test of time, but only time will tell that.One tip. If you're having issues getting them to slide onto your polycarbonate panels, dawn dish soap is your best friend. Just put a tiny bit on the edges of the polycarbonate panel and it'll slide right in. ### ⭐⭐⭐⭐⭐ Just what i needed *by on Reviewed in the United States July 21, 2026* These fit both width and length. Exactly what i needed. No problem here. Other places sell for a LOT more but this was the cheapest and it also has great quality and quantity. ### ⭐⭐⭐⭐⭐ Satisfaction *by on Reviewed in the United States October 21, 2026* Exactly what we ordered ## Frequently Bought Together - Polycarbonate Greenhouse Panels U Connector Profile - 20 Pieces, 2ft Length, Prevent Dust, Rain & Moisture from Getting into Twin-Wall Panels, Fits 4mm (0.15 in) Panels (U Connectors 4mm-2ft) - Tatuo 12 Pack 4' X 2' X 0.16'' Polycarbonate Greenhouse Panels Polycarbonate Sheets Twin-Wall Roof Panels Waterproof UV Protected Clear Corrugated Plastic Roofing for Greenhouse Replacement --- ## 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/667454071-owlhaus-polycarbonate-greenhouse-panel-connectors-u-channel-4mm-20-pack](https://www.desertcart.kr/products/667454071-owlhaus-polycarbonate-greenhouse-panel-connectors-u-channel-4mm-20-pack) --- *Product available on Desertcart South Korea* *Store origin: KR* *Last updated: 2026-10-27*
