    I have an old Skil belt sander that I stopped using because I could not find belts for it. I am thrilled that I was able to get them from you. They work great. Thanks

    Great Value BETTER Service

    Ordered 10 4" wide belts. First 4 came apart within 1 1/2 minutes. Called them on Friday and they sent 12 not 10 and they arrived on Sunday. New ones work great Never asked for old ones back. Way cheaper than Big Box stores if they have what you need. Deserve 5 stars for service alone.

    Belts work great, prompt delivery

    My 4" sander is of course my work horse for large heavy jobs. Bought mine about 35 years ago from Kmart and it works great today. Very hard to find 21 3/4" belts today so much that I have considered discarding it. I love the sander and am pleased that this company still provides them.

    Best sanding belt purchase

    Posted by Jerry on 03 05 2019

    My antiquated Wards belt sander was useless without sandpaper. The 4” x 21-3/4” size isn’t available locally.
    I found that 2Sand has all sizes. Ordering was easy and shipping was fast. I’m very pleased and will order from 2Sand when I need sandpaper.

    Good belts for my old sander

    Posted by Mr. Jerry on 03 05 2019

    I love my old Skil belt sander but the 21 3/4" belts got to be hard to find. The 100 grit belts were delivered quickly and do a great job on cabinets I am building. The flat seams on the belts allow them to be run either direction but without the seam thumping every revolution the finished work is smoother. I will keep coming back to for all my sanding belts.
