I have analyzed these options and compared the feedback to see what actually performs under pressure. In my view, the right choice depends entirely on your specific maintenance needs. Let us look at the performance rankings to see which parts keep your Delta running smooth.

These strips earned their spot because they excel at the final pass. When you need a glass-smooth finish without burning your workpiece, these are the clear choice for the job.
I find that having these on hand is essential for high-end projects. They provide the consistency that makes a piece look professional rather than merely functional.

3. 120 Mesh Drum Sander Conveyor Belt 18 x 47-1/2 Inch Fit for Delta
You might be surprised to learn that the mesh design helps prevent dust buildup, which is a common problem with standard solid belts. This feature keeps your workpiece moving without the jerky motion caused by sawdust trapped under the feed path.
I believe this is a smart choice if you work with woods that produce fine, clingy dust. It breathes better than rubberized alternatives, which helps your sander performance.
The mesh structure is highly regarded for its resistance to loading up.
Installation is reported as straightforward by most users.

The most common complaint regarding this belt is the initial difficulty in getting the tracking centered, though this is a standard hurdle for almost any drum sander belt. Once you spend a little extra time on the adjustment, the belt stays put and offers excellent durability.
I consider this the gold standard for maintenance because of its build quality. It is the one I would point most people to when they need a reliable, long-term solution.
The robust construction is frequently cited as its biggest advantage.

5. Pre-Cut Strips for Delta 18-36 Drum Sanders, Pack of 4 2SAND Pre-Cut Strips for Delta 18-36 Drum Sanders, Pack of 4 (36 Grit)
Compared to the 180 grit strips, these are built for raw power rather than finesse. They earn their place by being the heavy lifters of the shop, capable of aggressive stock removal on rough sawn lumber.
I appreciate how these strips handle deep scratches and uneven joints. They are the first step in any restoration project where the surface is particularly nasty.
These are essential for quickly leveling large, uneven boards.
Users report that the backing material holds up well under high heat.
They are best used for the initial dimensioning of your stock.

6. Pre-Cut Strips for Delta 18-36 Drum Sanders, Pack of 4 2SAND Pre-Cut Strips for Delta 18-36 Drum Sanders, Pack of 4 (60 Grit)
These became popular because they occupy the middle ground between heavy leveling and fine sanding. Many users find this grit to be the versatile workhorse that they reach for most often during a project.
In my judgment, this reputation is well-earned. It removes material quickly enough to save you time, yet leaves a surface clean enough for a final pass with a higher grit.
These strips are praised for their longevity during mid-range sanding.
The fit on the drum is consistently reported as precise.
They are considered a staple for most hobbyist woodworkers.

7. JET 16" Drum Sander w/Stand, SandSmart Auto Feed Control (JWDS-1632)
This machine earned its ranking because the SandSmart control is genuinely superior at preventing gouges. It automatically adjusts the feed rate, which is a lifesaver when you are working with figured grain or wide panels.
While it is a different machine than the Delta, it is a great alternative if you are looking for a complete system upgrade. I find the build quality to be quite high for the price point.
The auto-feed feature is the most frequent highlight in positive reviews.
It provides a very high level of control for delicate work.
The stand is noted for being sturdy and vibration-free.

This sander is best for the budget-conscious workshop that needs a complete, standalone solution with extension tables. If you are setting up a space for cabinet making and need extra support for long boards, this is a very capable option.
I think the dual motor setup is an interesting touch for this price range. It separates the drum rotation from the feed belt, which gives you much better control over your finish.
The extension tables are highly valued for supporting long stock.
Users appreciate the clear and functional dust collection port.

Choosing Between Them
The Monarch Industrial conveyor belt is my top choice because it offers the most dependable fit for specific Delta 31-250 and 31-252 models. For those needing specific abrasives, the 2SAND pre-cut strips are excellent for anyone from the heavy-duty stock remover to the fine-finish specialist. If you are looking for a full machine replacement, the JET 16-inch sander serves the professional who needs auto-feed precision, while the VEVOR 16-inch unit suits the workshop that requires an all-in-one setup with extension tables.
Please keep in mind that maintaining a drum sander requires frequent attention to both your abrasive strips and your conveyor tracking. No matter how high-quality your parts are, they will eventually wear down if the machine is not cleaned or if the dust collection is left to clog. I suggest checking your tracking every few hours of use to ensure you are getting the best results from these essential components.
