Colson 4 Series 6" x 2" Performa Flat Tread Wheel Swivel Caster – 4" x 4.5" Top Plate, 600 lb Capacity, USA-Made Quality
The Colson 4 Series 4.06109.459 swivel caster pairs Colson’s legendary 6" x 2" Performa wheel with the most trusted 2"-wide rig in the industry. Built for heavy-duty applications and unmatched durability, this caster supports up to 600 lbs dynamic load capacity per caster and is ANSI ICWM tested for long-lasting performance and safety.
The Performa wheel—often imitated but never duplicated—is the world’s best soft wheel, delivering quiet, smooth rolling with superior shock absorption, debris rejection (including metal shavings), and chemical resistance. Its flat tread profile boosts load capacity and stability while maintaining floor protection and easy maneuverability.
The 4 Series rig is engineered for the toughest jobs, featuring a 3/4" permanent rivet kingpin (vs. the 5/8" industry standard) for superior strength and service life. Full double ball hardened raceways, a 1/4" thick top plate, and grease fittings on both the swivel raceway and wheel ensure smooth operation and easy maintenance.
