Review on Enhance Furniture Mobility Effortlessly with Shepherd Hardware 9240 1-Inch Square Adhesive Slide Glide Furniture Sliders, 8-Pack by Trevor Bannister

5 stars even though the screws provided do not fit my Ghost chairs. The chairs have a grippy silicone insert on the underside of the legs, exactly the same size as the Shepherd sliders, but the screws need to be a bit longer for penetration. I temporarily used the glue option until I found the exact screw size I needed. Too short - they don't penetrate silicone, too long - they hit the hard plastic of the chair, weakening it as a result. I'll find them and make a permanent mount, but the self-adhesive sliders are still in place for now. Silicone grips are the exact opposite of what is needed for vinyl floors and make it difficult to move chairs under the table. Shepherd sliders are the perfect solution to this problem. UPDATE 9/14/17: Properly sized screws are now installed for plastic chairs with pilot hole pre-drilled and tightened. I'm very happy with the result because I feel it adds more security to these rather expensive chairs. The length of the screw is by no means a fault of Shepherd Hardware, they include screws that would fit almost any other chair, but ghost chairs have about an inch of room before the screw hits its mark. UPDATE 3/26/18: 6 months later, not a single issue with them staying bolted down and sliding nicely on the vinyl floor.
