Poly Grain Bin Accessories
Poly Feed Bin Attachments
These poly feed bin boots, auger boxes, and slide valves are designed to fit our plastic grain bins, and even though they're at the bottom of the bin where water tends to collect, there is no rust with poly construction. Make sure your grain bin lasts for a long time without the risk of rust or corrosion with a poly feed bin, slide valves, and unloaders from Barn World!
Slide Valves, Auger Boxes & Poly Boots for Reliable Grain Flow
Upgrade your bulk storage and feed systems with Barn World’s Poly Grain Bin Accessories. Our durable polyethylene slide valves, angled collars, auger unloader boxes, and poly boots are engineered to deliver precise flow control, minimize waste, and keep your grain-bin management system operational, safe, and efficient. Ideal for livestock producers, feed mills, and farm supply retailers, these components are maintenance-friendly, corrosion-resistant, and simple to install.
Grain Bin Slide Valve — 30° Angle
The 30° angled poly slide valve improves gravity-assisted flow for bins that experience bridging or material buildup. Built from heavy-duty polyethylene, this valve reduces hang-ups for fine or high-moisture grains and integrates smoothly with auger systems for continuous discharge.
- Primary use: Gravity feed / reduce bridging into augers
- Benefits: Improves flow, lowers manual clearing, reduces waste
- Why required: Ensures consistent discharge from angled hoppers and prevents downtime
Grain Bin Slide Valves — Straight Slide Valve
Our straight poly slide valves are the backbone of precise bin output control. Designed for direct-fit installation on grain hoppers and portable bulk bins, these valves provide smooth, reliable opening and closing action to meter grain for feeding, loading, or auger intake.
- Primary use: Metered discharge, feed rationing, fill control
- Benefits: Durable, weather-resistant, minimizes spills and product loss
- Why required: Accurate flow control reduces waste and improves feed-management efficiency
Collars, Boots & Unloader Boxes
Complete slide-valve assemblies—featuring poly collars, 30° boots, and auger unloader boxes—create a seamless interface between the bin and the material handling equipment. These accessories are essential for converting a raw storage bin into an operational system that feeds augers, conveyors, or loaders without clogging or unnecessary friction.
- Primary use: Adapter interfaces, auger connections, boxed unloading
- Benefits: Easier installation, reduced hang-ups, standardized fit for multiple auger sizes
- Why required: Proper mating components prevent bottlenecks and protect augers from uneven feed
Grain Bin Accessories Deliver an Efficient Grain Management System
- Operational: Slide valves and unloader boxes create a controllable discharge point so operators can dose, batch, and unload reliably.
- Functional: Angled valves and poly boots eliminate common failure points—bridging, compaction, and auger starvations—keeping systems running as intended.
- Efficient: Reduced clean-up, lower product loss, and better integration with augers and conveyors increase throughput and reduce labor costs.
