Round Rubber End Caps
How often do you find yourself wanting to cover up a loose screw or any kind of sharp edge but you just do not know how to do it or what to use to cover it up? Now, it does not only need to be a screw that needs covering, but you could also be having a baby or a small child in your household and you simply need to cover up the edges for protection and safety. Well, in those cases, you need round rubber end caps. A round rubber end cap is exactly as it sounds, it a rubberized cap that is used to cover up sharp edges of whatever object to protect both you and those loose ends.
Now, the application for round rubber end caps can be various. Like we’ve said, you could use the small round rubber end caps to cover up bolts or screws. You could even use these to cover the sharp edges on your coat rack or even things like scissor ends or some kitchen utensils. Maybe you don’t want to risk breaking the tip of your knife, so you cover it up with a round rubber end cap. Furthermore, these could be used to cover the ends up pipes and hoses, as well.Now, since these are made from all kinds of different rubber, they’re very elastic and soft, not hard and stiff like plastic caps, so you don’t have to worry about them not fitting snuggly. Naturally, they come in a variety of sizes, even shapes. Some could have some extra depth, some could have some extra thickness – it all depends on what you plan on using them for. They offer great protection and insulation, from water, dust, heat etc. This makes them applicable in a lot of different ways.
Naturally, if you need some extra small or large ones, we could custom make them for you.
