I purchased this shelving: Seville Classics 5-Tier UltraZinc Steel Wire Shelving Unit/Wheels, 14"(D) x 30"(W) x 60"(H) to put in a utility closet to put it where I needed to be able to remove it to move my server rack back and side while I work with it.This rack is rated for up to 130 lbs but I don't think the wheels are 75 lbs for longer ones Being able to keep time. Mine eventually broke (had a lot of board games mostly.) I was looking for new videos but was absolutely trying to stay away from the likes of this one. I thought they were all cheap and wouldn't last in any way. I'm just into it Assumed they were broken like the originals that came with the Regal. Unfortunately I couldn't find another wheel with the same threading (1/4-20). I read some reviews and they suggested they were made by be of better quality, a lso I tried them. HOLY COW, these things are great! They are day and night compared to those who replaced them. No more worrying about them breaking down like the old ones. The role is great and they take the weight without batting an eyelid. If you have a shelf like the one above and are looking for spare casters, GET THESE! There is no reason to look any further.
