Need to make your clothes rack, wire shelving, or storage unit mobile? These 2-inch locking stem caster wheels are just what you're looking for. You get a set of four, each with a threaded stem that fits standard 3/4-inch posts (the kind on many garment racks and wire shelves). Each wheel can hold up to 100 pounds, so the whole set supports 400 pounds—plenty for most racks or carts. They swivel 360 degrees for easy maneuvering, and the side lock brakes keep your unit firmly in place when you don't want it to roll. The wheels are made from non-marking thermoplastic rubber, so they roll quietly and won't scratch your floors. The construction is heavy-duty steel, so they're built to last. Perfect for making your storage mobile, improving accessibility, or just adding wheels to a DIY project. Just make sure your rack has a 3/4-inch post before ordering—these won't fit 1-inch posts. Easy to install and super handy!
