Just pull out the worn ones and tap new ones into the same holes as the old ones. Very easy and my replacement pads held well in the old holes. I used the same exact pads by Shepherd, from Home Depot so they would fit.
Scorpio, thank you for your question. Yes, we do offer the 1.5" only in 4-packs. Unfortunately, Home Depot does not list for purchase on their website. However, if you can go into your local Home Depot store and go to the Pro Desk, they can call us at 800-645-8990 and request a "special order" for you. the part number for our 1.5" 4-Pack is 9935. I hope this information helps.
20 pack contains four 1.5" pads and 16 of the 1" pads. Enough for a table and four chairs.
They are currently not available in brown.
