This is a functional belt, designed to keep your pants up. It is heavy, high quality leather, and the buckle is also heavy duty. It has a nice design, but nothing too elaborate. If you want a belt to wear with your jeans that does the job, this is your belt. Review: Perfect fit for an older 4x36 belt sander - I have an older Craftsman benchtop belt sander. Lately, I have been unable to find the 4x36" belts that fit. If I do manage to find them, they are overpriced and only available in 80 grit. I was pleased to find this assortment pack on desertcart. Since it contains 3 of each of the grit size belts I use most often, it should be a long time before I need to reorder. The price is unbeatable too (only slightly more than the home improvement store wanted for an 80 grit 2 pack). The belts fit perfectly on my sander and appear to be very good quality. So far so good. ## Features - Made with Premium Aluminum Oxide grain - The belt interface is firm and will not break easily By the Diagonal lap splice technology - It is mainly used for wood / aluminum / non-ferrous metal / glass / plastic / stone ect - Antistatic, washable plus an additive in the resin to resist loading - 12 PCS assortment includes 4 each of 80 / 120 / 150 Grits ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B07WTP6YKB | | Batteries Included? | No | | Batteries Required? | No | | Best Sellers Rank | #1,698 in Tools & Home Improvement ( See Top 100 in Tools & Home Improvement ) #1 in Sander Belts | | Color | Red | | Customer Reviews | 4.7 4.7 out of 5 stars (6,974) | | Date First Available | August 20, 2019 | | Item Package Quantity | 1 | | Item Weight | 1.25 pounds | | Item model number | 75 x 533mm | | Manufacturer | Ur-Excellent | | Material | Aluminum | | Part Number | 3x21in | | Product Dimensions | 6.2 x 4 x 4 inches | | Size | 3x21in | ## Images ![3x21 3 x 21 Inch Sanding Belt Pack 3-Inch x 21-Inch,12 Pcs(4 Each of 80 120 150 Grits) Aluminum Oxide for Sander - Image 1](https://m.media-amazon.com/images/I/71gicJ3Lo4L.jpg) ## Available Options This product comes in different **Size** options. ## Questions & Answers **Q: is the 4x36 the 4 inch wide by 36 cercumference?** A: Yes. **Q: Will these fit my Delta model SA180?** A: Should work on your Delta SA180. Delta online manual calls for 1” x42” belt. **Q: Will these work on a WEN 3x21 belt sander?** A: Check the manufacturer's model number for a match. **Q: Connecting belt-how do you connect the belt** A: The front roller (wheel) of belt sanders can be moved back to install the belt. There should be a lever on the side which when pull out, will move that roller in. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Great value, great quality *by D***C on January 20, 2026* I was pleasantly surprised by the quality of this product.

Lately, I have been unable to find the 4x36" belts that fit. If I do manage to find them, they are overpriced and only available in 80 grit. I was pleased to find this assortment pack on Amazon. Since it contains 3 of each of the grit size belts I use most often, it should be a long time before I need to reorder. The price is unbeatable too (only slightly more than the home improvement store wanted for an 80 grit 2 pack). The belts fit perfectly on my sander and appear to be very good quality. So far so good. ### ⭐⭐⭐⭐ Affordable value for 4x24 belt assortment *by P***T on May 27, 2024* The quality/value of sanding belts can be judged both on how long they remain effective while sanding, and on the uniformity per labeled grit, against the cost per unit. These belts compare very favorably on cost (roughly half) vs. another manufacturer whose belts I have previously been using, and the uniformity of grit is near as good as far I can tell with just a visual inspection. However, they definitely don't last as long, but the longevity comparison has been more than half, so they are still an attractive value. I haven't kept good enough data to precisely quantify the value advantage, but if forced to guess I would say they result in a savings of maybe 10 to 20% overall. As a consumable commodity, just expect to use more belts per project than if using premium belts. For context, I'm using them on a Rigid oscillating sander, with hardwoods and BB plywood edges. I have not experienced these belts separating at the joint as other reviewers have mentioned, but even premium belts that sat for over a year have separated on me relatively quickly when put to use (I had two from the same batch do that). Neither resulted in damage to my oscillating sander, and I was able to fasten those two belts back together for full functionality with a Tyvek patch cut from a mailing envelope, adhered with ordinary Elmer's glue (in place of the original joining tape), so for me any future belt separation would be inconvenient, but not a big worry. Perhaps reviewer's whose belts separated had received belts that had aged in a warehouse too long? And perhaps machine damage is a bigger issue depending on type of machine. Obviously, that's speculation, just things to think about. In my own experience I've worn out three of these particular 4x24 belts so far with no separations, and I consider the value they offer to be above average. The grit range (80, 120, 150) matches what I use most, they fit my oscillating sander perfectly, and none had problems tracking. ## Frequently Bought Together - 3x21 3 x 21 Inch Sanding Belt Pack 3-Inch x 21-Inch,12 Pcs(4 Each of 80 120 150 Grits) Aluminum Oxide for Sander - WEN 6321 7-Amp 3 in. x 21 in.
