Instructions were not that easy to follow but i figured it out. ### ⭐⭐⭐⭐⭐ Keeps people from slamming doors. *by on Reviewed in the United States March 21, 2025* Easy to install. Makes it impossible for anyone to slam my office door.Good product. ### ⭐⭐⭐⭐ Product is fine. Delivery was mishandled!!! *by on Reviewed in the United States September 18, 2024* This product is fine however the delivery was not done in a professional manner. The delivery person placed the package on a chair on m porch and then moved the chair in front of my outward opening storm door thus blocking my ability to open the door (see photo). I had to knock the package onto the porch in order to get the door open to retrieve the package. Had this package contained anything fragile it could have been damaged. PLEASE pass this on to the delivery people to not move furniture on my porch so that is blocks the door from opening. Thank you. ## Frequently Bought Together - LYNN HARDWARE Medium Duty Commercial Door Closer - DC6003 Automatic Door Closer, Surface-Mounted Auto Door Closer, Size 3 Automatic Door Closer for Home & Light Commercial Property, Aluminum - Dynasty Hardware Push Bar Panic Exit Device for Emergency Exit Doors Painted Aluminum, with Exterior Lever Handle - LYNN HARDWARE Medium/Heavy Duty Commercial Door Closer - DC7016 Surface Mounted, Grade 1- ADA & UL 3 Hour Fire Rated, Adjustable Size 1-6 for entrances & Aluminum storefronts- US26D Aluminum --- ## 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.gr/products/116518443-medium-duty-automatic-door-closer-durable-cast-aluminum-commercial-home](https://www.desertcart.gr/products/116518443-medium-duty-automatic-door-closer-durable-cast-aluminum-commercial-home) --- *Product available on Desertcart Greece* *Store origin: GR* *Last updated: 2026-08-16*
