Description

Colson 2 Series 5" x 1.25" Performa Wheel Swivel Caster – 1/2"-13UNC x 1-1/2" Threaded Stem, Sealed Precision Ball Bearings

The Colson 2 Series 2.05254.445 MTG53 swivel caster combines Colson’s proven 2 Series rig with a 5" x 1.25" Performa rubber wheel and a 1/2"-13UNC x 1-1/2" threaded stem mount. Designed for industrial, institutional, and commercial environments, this caster supports up to 325 lbs dynamic load capacity and is ANSI ICWM tested for lasting performance and safety.

The Performa wheel outlasts traditional TPR and rubber wheels, delivering shock absorption, debris rejection (including metal shavings), chemical resistance, and non-marking floor protection. Sealed precision ball bearings provide ultra-smooth rolling, reduce push/pull force, and protect against contaminants—making this caster ideal for demanding, high-usage applications.

  • Floor Protection – Non-marking tread safe for finished floors
