Fabbay Multi Purpose Rubber Spacer 1 OD x 3/8 ID x 1/2 Inch Thickness Black Round Rubber Washers Anti Vibration Bushings Spacers Washers for Home and Car Accessories(8 Pcs)

Used these on an attic fan installation to reduce vibration transfer. So far, works well. Glad I got them

This product is excellent and I have purchased them multiple times. In my application, I used them to adjust the height of landscape edging for my pavers to keep mulch off the pavers. With pavers usually, they are held with concrete to maintain them from moving. So in some cases, I used the spacers to elevate the landscape edging up more than 2 inches as I did not need 4 Inch height edging but wanted something in between. I bore 3/8" holes in the concrete, add spacer and secured them with the 8 inch hails. This held everything very good. Some ingenuity for my application, but these spacers did the job. Highly recommended.

Works like it should!

It served its purpose to replace a broken spacer. Nothing special.

Exactly what I needed

Used these to offset my TV wall-mount from the wall a bit, to protect the wall/paint. Just thread the lag bolts through these behind the mount and they work very well.

I used these to dampen excessive vibration on my mower's tensioner spring. The vibration was so bad that the eye bolt was being mechanically eroded by the spring rubbing against it. Adding these bushings removed almost all of the vibration.

Perfect fit
