DGQ Short Chair Glides Replacement Low Profile Bell Glides Replacement Chair Wheels Stopper Fixed Stationary Caster Glide for Office Chair Desk Chair

These are 11mm not 7/16 I measured them with a caliper.I also measured the original wheels they were 7/16 not 11mm.The originals were1 7/8" long.These are much shorter, but I knew that.But they work just fine !!!I didn't have to modify them in any way.When you put them with no load at all they wobble.As soon as a load is applied (like the chair) they stop wobbling.The chair is much more stable.And the chair gives better support to my back because it doesn't move away.These gliders only glide when you have little weight on the chairto you have to lift up on the chair.I don't want my chair scooting asway from me.Larry in NH.

I bought this as I needed to keep my gaming chair in place for when I was Sim Racing, so easy to install and the chair feels very sturdy and it doesn’t move an inch.

Easy to install and we have not had any issues. I put felt pads on the bottom to make them easier to move and protect the floors.

Fit perfectly
