Featuring a plunger-activated drop bar seal housed in a sleek anodized aluminum case, it offers durable, quiet operation ideal for uneven floors. Easy to trim and install, this ambidextrous, surface-mounted solution enhances door aesthetics while providing effective draft and pest protection. ## Description Pemko automatic door bottoms consist of an aluminum case which surrounds a movable drop bar seal. The drop bar seal is actuated by a plunger which contacts the jamb as the door is closing, forcing the drop bar seal down against the floor or threshold. Review: It solves the problem upgrading the appearance of the door. - The floor inside the house was not even, so the door has to have a 1/2" gap. With this door bottom, the problem is solved by adding an accessory with a great appearance and a good and simple technology. When I saw it first after opening the package, I repacked it back and almost returned it. It looked like it wouldn't work properly when installed. But then I realized that both sides had to be flush and I made a simulation at a small distance from a flat surface (it could be any floor as well), and the product worked excellently. After installation, what I could see was that the product worked as it did in the simulation, and hopefully, it will continue that way for a long time. It is important to be extra careful not to cut too much. I needed a piece with 34 3/4" to fit perfectly in the door, but first I cut it with around 35 3/8" to check if the cut was going to come out OK. I used a grinder with a thin disc for metal to cut but probably a miter saw with a normal or trim blade would do an easier and more accurate job. The cut has to be super precise with less than 1/16" of error if possible. That is why is important to cut it bigger and even sandpaper the last 1/16" to make sure there is the least possible gap. Putting a piece of wood or something else on top of the door bottom to guide where the miter saw will cut will help to get the exact cut every single time as well. My first review was on February 21st of 2021. The product is excellent. It only had a little problem once atthebeginning, because I put it to tight. I adjusted and it never failed or didn't work properly again. And stays like new. Some wd-40 now and then will help as well. Review: Works as expected - My storage room door in our condo garage had a gap under it that I couldn't seal (to protect from small critters) because of the unlevel floor. This took care of the problem. My storage room door opens into my storage room, so this mounts on the outside of the door and is as unobtrusive as the cheap non-adjustable plastic door bottoms that others use here. With this door bottom installed, I was able to lay some cheap carpet on the storage room floor. Because this door bottom immediately pops up to door bottom height as the door is opened, it clears the carpet inside the room, and drops to seal the bottom of the door when it's closed. Installation is easy, but only after the Door Bottom is trimmed to fit. My recommendation if you've never installed on of these before: Read the instructions. Read the instructions again. Measure twice. Measure twice more. Cut once (carefully). Once it's the right size, installation is simple. Overall, this shouldn't be a problem for a confident DIYer. ## Features - Made in United States ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B009UWKBVC | | Additional Features | Easy to Install | | Best Sellers Rank | #280,246 in Tools & Home Improvement ( See Top 100 in Tools & Home Improvement ) #585 in Screen Door Hardware | | Brand | Pemko | | Brand Name | Pemko | | Color | Clear | | Customer Reviews | 4.0 out of 5 stars 134 Reviews | | Exterior Finish | Clear Anodized | | Finish Types | Anodized | | Global Trade Identification Number | 00086787119821 | | Hand Orientation | Ambidextrous | | Handle Attachment Mechanism | Surface Mounted or Semi-Mortise | | Handle Material | Aluminum | | Handle Type | Pull Handle | | Included Components | Bolt | | Indoor Outdoor Usage | Indoor | | Item Depth | 1-27/32 inches | | Item Dimensions L x W | 36.4"L x 1.9"W | | Item Weight | 0.27 g | | Manufacturer | Pemko Manufacturing Company, Inc. | | Manufacturer Part Number | 4131CRL36 | | Material | Aluminum | | Material Type | Aluminum | | Metal Type | Aluminum | | Model Number | 4131CRL36 | | Number of Items | 1 | | Product Dimensions | 36.4"L x 1.9"W | | Shape | T-Shaped | | Specific Uses For Product | Door | | Style | Modern | | Style Name | Modern | | UPC | 086787119821 | | Unit Count | 1 Count | ## Product Details - **Brand:** Pemko - **Color:** Clear - **Material:** Aluminum - **Product Dimensions:** 36.4"L x 1.9"W - **Style:** Modern ## Images ![Pemko Automatic Door Bottom,3/8x36 in,Aluminum 4131CRL36-1 Each - Image 1](https://m.media-amazon.com/images/I/71A1c232G+L.jpg) ## Questions & Answers **Q: Available in black or brass?** A: This product is available in Dark Bronze Anodized (a very dark brown, close to black). Please contact our office (Trademark Hardware) during business hours for assistance. Reference product SKU P4131DRL. **Q: How much of a gap can this cover? The floor is dropping. One side of the door is 1 1/2 inches and the other side is 1/2 inch** A: No, this will not work with a large gap as you described. To the best of my knowledge it works on approximately a 3/8” gap. **Q: will this item surface mount?** A: Yes, it does surface mount at the bottom of the door. It is very easy too mount to the door. **Q: Can the door sweep be mounted on the door exterior to prevent rain from coming in under the door?** A: If you put a piece of wood or Azek with an angle (45 for example) on top of the bar, the water would not accumulate and you would have a great product on your door. ## Customer Reviews ### ⭐⭐⭐⭐⭐ It solves the problem upgrading the appearance of the door. *by M***A on February 6, 2021* The floor inside the house was not even, so the door has to have a 1/2" gap.

It does work as advertised. *by P***T on June 29, 2023* Pro- When adjusted correctly the drop seal works well Con - the screw that is supposed to keep the adjustment screw from backing out is so small as to be nearly impossible to screw into the bar. Con- The screws that come with the seal kit are not hardened, hence not very durable. Con- It would be nice to have more than 3 mounting holes. ## Frequently Bought Together - Pemko - 4131CRL36 Aluminum Automatic Door Bottom, Clear Anodized, Insert, 19/32”W x 36"L x 1-27/32”H - Pemko S88BL20, Black - Pemko - S88D18 SiliconSeal Adhesive-Backed Fire/Smoke Gasketing, Dark Brown Silicone, 0.5" W x 0.25" H x 18' L --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.us/products/14574071-pemko-automatic-door-bottom-3-8x36-in-aluminum-4131crl36-1](https://www.desertcart.us/products/14574071-pemko-automatic-door-bottom-3-8x36-in-aluminum-4131crl36-1) --- *Product available on Desertcart United States of America* *Store origin: US* *Last updated: 2026-08-21*
