These Everbilt Furniture Sliders are a perfect fit. They have remained under my Townsend Podiums from the getgo. They come with socks if you have a hardwood floor. Definitely, not decor friendly.
Recently, I did a major repositioning of my speakers (120 lbs each) on a thick pile carpet. They slid very easily. It would have been impossible to dial the toe-in without them. It’s extremely important to get down on your hands and knees to grasp the podiums - NOT the speakers. Slide very slowly. When repositioned, the pods on each podium will need to be realigned. Very carefully, tip the speaker back & forth to listen for rubbing of the pods’ shaft on the podium platform. Just realign by centering the pods’s shaft within the hole. It should take only a few seconds. The podiums won’t be working properly if the rubbing remains.
It would be a challenge to do this frequently. Good luck!
