How Do You Make Tennis Balls On A Walker Take A Licking And Keep On Ticking?
The (deflated/cut) tennis balls are on the legs of the walker to “protect” the floors of the facility and to make the walker less like to “snag” on carpeting (possibly resulting in a fall). You could try stick-on felt protectors that go on furniture legs (example) as an alternative.
My thought is that you should be sure the tubes are capped inside the balls or you might be getting a “cookie cutter” effect. A cheap-to-free fix would be to glue an appropriately sized bottle cap or a film canister onto the leg. A slightly more expensive but vastly more durable solution would be to glue on a PVC pipe cap. Warning: this fix will be super slippery on wood or tile, and won’t address the issue of transitions from tile to carpet or raised weather sills in doorways, which is where the tennis ball fix really shines. With a slightly higher investment, you could purchase solid rubber balls, have maintenance drill them out about halfway with a Forstner bit (using a bit just slightly smaller than the leg diameter) and press them on.
