Overview
The Action Industries DOS83 is a professional-grade PVC bulb bottom weather seal built for mini warehouse, self-storage, and rolling steel door applications. Designed to slide directly into compatible Janus and Amarr bottom retainers, this vinyl bottom seal closes the gap between the door and the floor to block drafts, dust, moisture, insects, and rodents from entering your storage units or commercial bays.
Manufactured in the USA from durable black PVC, this replacement door bottom seal delivers consistent, long-lasting weather protection across a wide range of temperatures and environments. It is available by the ft. for single-door projects or in a 100 ft. reel for multi-door facilities and maintenance teams working across an entire self-storage property.
Features and Benefits
- Bulb-style sealing profile — the 1 in. PVC bulb compresses against the floor to create a tight, continuous barrier at the bottom of the door.
- 3/16 in. T-end attachment — slides securely into compatible Janus and Amarr bottom retainers without additional hardware.
- Durable black PVC construction — resists cracking, UV damage, and wear for dependable service life in demanding environments.
- Sold by the ft. or 100 ft. reel — order only the length you need, or stock up with bulk reels for large-scale replacement projects.
- Single-piece shipment — ft. orders ship as one continuous piece for clean, gap-free installation.
- Made in the USA by Action Industries, one of the largest astragal seal manufacturers in the world.
Compatible Door Models
- Amarr: 2743, 5101, 5501, 5601, 5652
- Janus: 650, 750, and 850 Series
Before ordering, verify that your existing bottom retainer accepts a 3/16 in. T-style seal. Wayne Dalton, DSI, and Overhead Door mini warehouse doors use different retainer profiles and require a different seal. If you are unsure which retainer is installed on your door, contact the Barron Equipment team with a photo or measurement and we will help confirm compatibility.
Applications
This vinyl bottom seal is used across a range of commercial and self-storage environments where consistent weather sealing at the bottom of the door is essential. Common applications include:
Self-storage facilities — Replace worn, cracked, or flattened bottom seals across dozens or hundreds of unit doors using the 100 ft. reel for field-cut lengths. Proper floor-level sealing helps protect tenants’ belongings from water intrusion, dust, and pest entry.
Mini warehouses and commercial garages — Rolling steel and sectional doors in commercial mini warehouse buildings rely on a tight bottom seal to maintain environmental separation and reduce energy loss.
Rolling steel door maintenance — Facility maintenance teams and door service contractors use the DOS83 as a direct replacement for worn OEM seals on compatible Janus and Amarr doors.

Installation Tips
This replacement bottom seal slides into the existing compatible bottom retainer — no special tools or additional hardware are required. Following a few best practices will help ensure a clean installation and reliable long-term seal performance:
Close and lock the door before beginning work. Remove the old seal from the retainer by pulling it out from one end. Clean dirt and debris from the retainer channel, and inspect it for bends, crushed areas, or damage that could prevent the new seal from fitting properly. Feed the T-end of the new seal into the channel and slide it across the full width of the door. A small amount of dish soap applied to the channel can help the seal slide more easily. For longer doors, having a second person assist can make the process significantly easier. Once installed, center the seal within the retainer and trim any excess material from the ends.
When measuring for your order, measure the door opening itself rather than the old seal, which may have shrunk or stretched over time. Order the door width plus a few extra in. to allow for trimming after installation.
