8pcs M8 Adjustable Rubber Furniture Levelers Screw in Threaded Furniture Legs Leveling Feet -Adjustable Furniture Feet –Iron Chair Leg Levelers -Floor Protector Heavy Duty Leveling Feet Glides

The pieces that came with my bed broke so I needed a replacement. I went to the hardware store to measure the exact size of screw that I needed which I recommend everyone do before ordering. It was M8 or 8mm. This product was exactly what I needed. It's expensive but worth it for the high quality and durability. I know that they will last a long time, it comes with 8 so I have many replacements, and I know that my floors will be protected.

These rubber protectors are not cheap at over $10 for a 6 piece. I have 4 patio chairs that has seen better days and the rubber leg cushions were all worn out. I took an old one off and measured the thread size and found out it was an M8 tread. Found these at Amazon and bought them to try it out. These are very well made. The rubber is solid and comes with M8 size. However they were longer and I used a Dremel tool to grind down some of the length and it fits like a champ. Now the chairs stopped digging into my patio deck.

Caterpillar wanted $20 for one of these. Its a bumper for the door on Cat skid loader. Now i saved $ and have spares

I guess I should have read more of the reviews, definitely not rubber, definitely not non-skid. The description is misleading, it states that it's a glide leveler, yet it's non-skid, doesn't make sense.

These foot height adjusters work very well. They have a longer shaft than those that normally come with adjustable foot chairs and tables. As a result they give you a bit more height to work with when trying to level chairs on uneven surfaces.
