Douglas Replacement Plastic Insert for Caster Chairs. #502B-1 Packed

Douglas swivel chair insert was great that they provided the inscription and information. Thanks, worked well

Perfect fit! Restored our dinette chairs to perfect working condition. Who knew it could be so easy?!

It took me three times to get the correct size. Amazon was great to accept returns. The sleeve was slightly larger than the diameter of the chair base tube. It did fit over the tilt/swivel mechanism good. Too install the sleeve and tilt/swivel mechanism into the base tube, place the mechanism on a hard concrete surface upside down, align the chair tube over the mechanism. Place a scrap piece of 2" x 4" x approx. 1' long over the chair tube and using a 3lb hammer drive the tube onto the sleeve until it is tight at the bottom. Be aware that during the impact the chair casters may come off. If so just reinsert them when finished. The tilt/swivel chair will now be like new. Be careful to order the correct diameter of the sleeve. The web site only gives the outside diameter of the sleeve and does not tell you the inside diameter of the chair tube it will fit. It is very easy to order the wrong size.

THEY ARE A LITTLE HARD TO GET STARTED IN THE TUBE BUT ONCE THEY START DOWN THEY GO OK JUST DON'T GET IN A HURRY. MY CHAIRS ARE LIKE NEW AGAIN.

We bought this to repair a squeaky kitchen swivel chair. My husband carefully measured the dimensions needed to fit our chair and ordered appropriately. The insert was way too small despite the stated measurements listed. My husband checked and the item and it didn’t fit the description. However it was easy to return.

This replacement Plastic Insert fit perfect and is exactly a match to the original part. The measurements on the picture were dead-on for sizing. Thanks, great product and will order again when needed!

Bought 2 of these to replace broken inserts on patio chairs. I've replaced the inserts before (same size as these) and had no problems. With these, they were a bit of a problem. I dont know if these were factory seconds or not, but the first plastic ring that goes down into the chair base was too big - the insert would not slide in, or even pound in. I had to use a utility knife to trim the insert a little all the way around before it would fit into the chair base, allowing me to pound it the rest of the way in with a rubber mallet (pounding these in is normal for these inserts - they must fit tightly to prevent seat wobble). After trimming that first ring, they fit fine - no wobble at all. The swivel action is REALLY tight though, which wasn't my experience with previous set I replaced. I'm hoping that it will loosen a bit as the chairs are used. Minus one star for having to trim and the tight swivel action, but not that big a deal, really. Shipping speed was good, and they work, so it's all good.

Had to put the Douglas Plastic insert in boiling water for approx. 10 min. to soften it for installation. Once the initial end was inserted, the rest followed by way of a 3lb. hammer and a 2X4. The shaft of the seat was inserted and one had to set upon the seat to force it to bottom out. Everything was tight and the chair returned to new condition.
