The best T-post gravity feeder depends on whether you want a complete feeder or an attachment for an existing setup. The On Time and REDNEK models are 80-pound options designed for T-post use; Banks Outdoors offers a smaller, adjustable-port feeder that can attach to a T-post. Moultrie’s kit suits owners of compatible Moultrie Quick-Lock feeders, while the two-way kit is for buyers supplying their own bucket or twist-on setup.
| Product | Best For | Capacity or Setup |

| On Time T-Post Gravity Feeder | Simple, low-maintenance feeding | 80 pounds |
| REDNEK T-Post Gravity Feeder | Large feed mouth and included mounting hardware | 80 pounds |
| Moultrie Gravity Feeder Kit | Compatible Moultrie feeder owners | Quick-Lock attachment |
| Banks Outdoors Feed Bank | Adjustable feeding flow | 40 pounds |
| Gravity Deer Feeder Kit | Bucket-based or twist-on installation | Bucket not included |
On Time T-Post Gravity Feeder

The On Time T-Post Gravity Feeder is an 80-pound-capacity feeder designed for buyers who want a straightforward gravity-fed option. Its listed features include a UV-resistant polyethylene design and operation without moving parts or batteries to replace.
Best for: Buyers who prefer a simple feeder without timers or battery changes. It is selected for its stated T-post design, 80-pound capacity, and low-maintenance operating approach.
Consideration: The product information does not list adjustable feeding ports or specific mounting hardware. Check the listing for mounting details before purchase if you need those components included.
REDNEK T-Post Gravity Feeder

This REDNEK feeder combines an 80-pound capacity with a 4-by-5-inch feed mouth. Its listed construction is heavy-duty, all-weather polyethylene. The removable cover is intended to make filling easier, and the product includes hardware and mounting bolts.
Best for: Buyers looking for a complete T-post feeder with mounting hardware and a roomy feed opening. Those listed features make it a strong fit when convenient filling and included installation parts matter.
Consideration: The listed product details do not specify adjustable feed flow. Choose another option if controlling the feed opening is a priority.
Moultrie Gravity Feeder Kit

This kit includes a Quick-Lock adapter, locking ring, and hose clamp. It attaches to a Moultrie Quick-Lock feeder using a twist-on, twist-off connection, converting a compatible setup to gravity feeding. The system does not use timers or batteries.
Best for: Owners of an existing Moultrie Quick-Lock feeder who want to switch to gravity operation without buying a new feeder. It is selected for its stated compatibility and included connection parts.
Consideration: This is a kit, not a standalone T-post feeder. It works with Moultrie Quick-Lock feeders, so avoid it if your current feeder does not use that system.
Banks Outdoors Gravity Feed Bank

The Banks Outdoors feed bank has a 40-pound capacity and can attach by strap to a fence, tree, T-post, or 4-by-4. Its adjustable feeding ports let users control feed flow. The product information also states that its single-post design will not interfere with or damage antler growth.
Best for: Buyers who want a smaller-capacity feeder with mounting flexibility and adjustable ports. It is selected for its explicit T-post attachment option and flow-control feature.
Consideration: Its 40-pound capacity is lower than the two 80-pound T-post models in this guide. Choose a larger feeder if capacity is your main priority.
Two-Way Gravity Deer Feeder Kit

This kit offers two installation approaches: convert a standard bucket into a gravity feeder or use a twist-on connection. It includes a locking clip and clamp to help secure the feed tube. The listed information describes a three-year limited warranty for eligible product issues.
Best for: Buyers who want installation flexibility and already have, or plan to provide, a suitable bucket or compatible twist-on setup. It is selected for its two stated installation options.
Consideration: The bucket is not included, and the product is described as an attachment rather than a complete feeder. Confirm your intended mounting arrangement before choosing it for a T-post setup.
Buying Guide: How To Choose A T-Post Gravity Feeder
Do you need a complete feeder or an attachment?
Start by checking whether the product is a full feeder or a conversion kit. The On Time and REDNEK products are presented as T-post gravity feeders. The Moultrie product requires a compatible Quick-Lock feeder, and the two-way kit requires a bucket or suitable twist-on arrangement. The Banks feed bank is a mountable feeder with a stated T-post option.
How much capacity do you need?
Capacity affects how much feed the container holds between refills. The On Time and REDNEK feeders each list an 80-pound capacity, while Banks Outdoors lists 40 pounds. The two kits do not provide a capacity in the supplied product details, so check their listings and the container you plan to use.
Do you want to control feed flow?
Banks Outdoors specifically lists adjustable feeding ports, which make it the clearest choice here when flow adjustment is important. The other product details do not state that their feed openings are adjustable. Do not assume a feeder has flow controls unless its specifications confirm them.
What should you verify before ordering?
- Confirm that the mounting method suits your T-post and installation plan.
- Check whether mounting hardware, a bucket, or an adapter is included.
- Compare capacity with how often you want to refill.
- For a conversion kit, verify compatibility with the feeder or container you already own.
- Consider whether removable covers, adjustable ports, or battery-free operation matter to your routine.
