Okay DIYers, listen up - these Bonsicoky rubber end caps are one of those simple things you don't realize you need until you have them! This pack comes with 24 black round caps that have a 20mm inner diameter (that's about 4/5 inches for us imperial folks). They're made from flexible PVC vinyl that's tough but still gives you a nice snug fit when you push them onto the ends of tubes, rods, or bolts. Perfect for protecting your furniture legs from scratching up your floors, covering sharp bolt ends on equipment, or just keeping dust and moisture out of metal tubing. They're waterproof, rust-proof, and won't rot or swell even if they get wet - so you can use them indoors or outdoors without worrying. Installation couldn't be easier - just push them on and you're done! Great for furniture legs, fence posts, machinery equipment, marine applications, or really any cylindrical object that needs a little protection. The black color is pretty universal and discreet, so they won't stand out like a sore thumb on whatever you're using them for. At 24 pieces per pack, you'll have plenty for multiple projects or to keep some extras in your toolbox for when you need them. Seriously, one of those cheap but super useful finds that makes you wonder how you managed without them!
