Premium Construction for Durability
Our 4-inch Expanding Stem Swivel Caster combines a press-steel zinc-plated bracket and a high-density polyurethane wheel to deliver long-lasting performance. The ball-bearing swivel mechanism ensures effortless 360° rotation, reducing operator strain.
Multi-Surface Compatibility
The non-marking PU wheel (4″ diameter x 1-1/4″ width) works flawlessly on delicate surfaces (linoleum, hardwood) and tough floors (concrete, tile). Perfect for workshop tables, hospital carts, and retail displays.
Heavy-Duty Performance
Each caster supports 350 lbs, making it suitable for loaded equipment. The 1-1/2″ expanding stem adapter fits standard tubular bases, ensuring a tight grip without slippage.
