These 4" forged steel dual wheel casters are built on the proven and reliable Heavy Service (HS) swivel caster platforms. This means you have lots of flexibility if you need to match an existing bolthole pattern or overall height dimension. The Heavy Service Dual Wheel Series features Hamilton’s Precision Integrated HPI™ Swivel Technology. The new technology outperforms conventional CNC-machined ball raceways, kingpinless, and unit load bearing swivel constructions. The Heavy Service Dual Wheel Series (HS2) is backed by Hamilton’s Three Year Product Warranty. Refer to selection table for qualifying wheels.
