Rubber plugs

A pretty easy way to shop for a high quality plug for the creative mind. Shipping cost shouldn't be there to make a profit.

Just what I needed

I went to several local hardware stores and plumbing supply companies but could not find the large stopper I needed. I found it on the WIDGETCO's website. The package was in my mailbox three days later.

Great Product, Flawed Description

The stoppers are just as expected. The quality of manufacturing is top notch. I'm dinging the star rating for the following reasons. The price seems a tad high per unit. Packaging of the stoppers is in units of 5 (at least my order) and returns are only allowed for packaged items, so you can't verify fit and return them if you've ordered incorrectly. Most importantly the item description for size 13 lists the material as silicone when they are in fact made of rubber.

[From WIDGETCO: Sorry for the typo in the description, we have fixed it. Thank you for bringing it to our attention. About the packaging, yes, these can be returned within 30 days for a full refund. We package small quantities to order but are easy to work with when it comes to returned.]

Lab Stoppers

Excellent product & fast shipping!

Maia C., Pennsylvania - 1/6/2014


The size 13 is perfect for covering the hole in a boat seat base mount. They don't make one and this is perfect.
