You may also drill a small hole through the center of the Knockout, and use a washer and a very long screw or bolt to secure the plug, but would require drilling a hole in the sink mold as well.  Applying Spray Release (sold here) prior to casting the concrete will make removal easier.\u003c\/li\u003e\n\u003cli\u003eRemoval- Prior to flipping over your concrete, loosen the edges of the Knockout with a flat head screw driver. Once the concrete piece is turned over, you should be able to push the Knockout free with your thumb and very little pressure.  If plug is difficult to remove, the center of the rubber can be drilled out, generally making the plug easier to get out while still being reusable.\u003c\/li\u003e\n\u003cli\u003eTo Clean- Scrape off any hardened concrete and\/or silicone.\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PNL Liners","offers":[{"title":"Default","offer_id":46517630992441,"sku":"gvd1789529225589","price":18.31,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0796\/9888\/6713\/files\/drain-hole-kitchen-plug-knockout-re-usable-rubber_1.jpg?v=1789529229","url":"https:\/\/tonalstylingoutfit.shop\/products\/drain-hole-kitchen-plug-knockout-re-usable-rubber","provider":"My Store","version":"1.0","type":"link"}
