The Colson D4.08109.839 SS WB29 swivel caster features a 8" x 2" Polyolefin wheel and a 4" x 4-1/2" Top Plate, capable of a 900 lb. capacity per caster. Complete caster specifications and downloadable CAD model are provided below. The Colson D4 Defender is the ideal 2” wide caster solution for customers requiring lasting performance and corrosion resistance. Manufactured from Type 304 stainless steel and polished, this series provides premium features and a critical defense to applications exposed to washdowns, cleaning agents, steam, caustic solutions, and other environmental conditions that eventually cause oxidation and failure in standard casters. From the standard FDA-approved performance food-grade grease, 3/4” permanent rivet kingpin, and top-performing wheels in the industry—including the Performa Rubber wheel—the Defender D4 will continue to perform through the toughest of elements.
• Constructed of highly polished, corrosion-resistant stainless steel (304 Grade)
• Top plate and legs formed from ¼" thick stainless steel for durability
• Legs precision welded to the yoke for strength
• Double stainless steel ball-bearing raceways (with zerk) formed smooth for ease of swiveling
