Tub Topper — For 40 & 110 Gal Tanks | Nag Bags
If you've got an old water tank that's been sitting in the corner since it sprung a leak, the Tub Topper is the simplest fix you'll find. It fits right over a standard 40-gallon or 110-gallon tank — the kind most barns already have lying around — and turns it into a proper slow feeder in minutes. The netting and elastic top come pre-attached, so setup is straightforward: secure it to the tub with your choice of hardware, fill it with hay, and you're done.
This one works well for horse owners who want the benefits of slow feeding without adding a dedicated feeder to their setup. It's also a practical solution for boarding facilities, show barns, and anyone who moves horses around and needs a portable option that travels with minimal fuss. The knotless netting is safe for shod horses, and the 1.5" and 2" mesh options let you dial in the right consumption pace for your animal — whether that's a steady grazer or a horse that tends to rush through a pile the moment it hits the ground.
The Tub Topper is hand assembled from durable nylon blend netting with a typical lifespan of three to five years under regular barn conditions. Hardware to secure it to the tub is sold separately. Water tank not included. If you're not sure which mesh size is right for your horse, reach out — we're happy to help you figure it out before you order.
