DH Casters 5 inch cast iron wheel 600 lb capacity gives a heavy-duty rolling solution where gates and fences need dependable movement under load. The cast iron construction handles up to 600 lb, so the wheel supports substantial weight in gate and fence runs that see frequent use. As a builders hardware caster accessory, this wheel drops into assemblies that require a separate wheel component, helping keep existing hardware layouts in service. The 5 inch diameter balances ground contact and maneuverability, which suits long, straight gate travel where stable rolling is more important than tight turning. The wheel design focuses on carrying heavy loads rather than ride softness, which matters on firm surfaces typically found around fence lines, yards, and service accesses.
The 600 lb load rating defines how the wheel handles heavy gate or fence sections, so it supports substantial structures without overloading the rolling surface. The 5 inch outside diameter sets how the gate meets the ground, keeping the rolling height predictable when aligning bottom supports to posts or tracks. Cast iron construction provides a hard running surface that holds its shape under sustained loading, which matters when a gate spends long periods resting on the wheel between movements. The roller bearings give the hub a smooth rotation point, so once the gate starts moving, it continues to roll with less resistance, reducing strain during repeated openings throughout the day.
This cast iron wheel is described for applications on gates and fences, so it fits jobs where a rolling support carries the weight of swinging or sliding sections. The 5 inch size suits fence lines where the gate travels along firm, generally level surfaces such as drive entries, service yards, or similar approaches. With a 600 lb capacity, the wheel can serve on heavier gate frames that support infill materials, so long as the design keeps loading within the stated limit. Being a builders hardware caster accessory, it matches projects where installers assemble a complete rolling solution from separate wheels, brackets, and structural members, keeping control over how the gate load is distributed to the ground.
The roller bearings inside the wheel support the hub on rolling elements, which reduces friction compared to a plain bore and lets the wheel start and continue moving more easily under heavy gate weight. That lower resistance during motion can help keep manual operation manageable on long or frequently used fence runs. The 600 lb rating sets a clear performance boundary, giving installers a defined figure when choosing wheel positions and spacing along a gate bottom rail. Cast iron construction keeps the running surface firm around the bearing area, which supports repeatable performance as the wheel cycles through many openings and closings in everyday use. The W-MP50158 identifier ties these characteristics to a single, repeatable component choice across multiple projects.
The DH Casters 5 inch cast iron wheel is described for applications on gates and fences, so it serves as a rolling support under those structures.
The wheel has a 600 lb capacity, which means it is intended to carry heavy gate or fence sections up to that load on the rolling surface.
The wheel uses roller bearings to reduce rolling friction at the hub, which helps heavy gates and fences move more smoothly when opened or closed.
Cast iron construction gives the wheel a hard, rigid running surface that supports the 600 lb capacity under typical gate and fence service conditions.
The 5 inch diameter balances ground contact and size, so the wheel can roll over small surface changes while keeping gate height and travel predictable.
The W-MP50158 part number identifies this specific DH Casters 5 inch cast iron wheel, helping installers match the same wheel across multiple gates.
The DH Casters 5 inch cast iron wheel 600 lb capacity pairs cast iron construction with roller bearings to support heavy gates and fences in regular use. For projects that demand a builders hardware caster accessory matched to defined load and size, this W-MP50158 wheel gives a clearly specified option that supports consistent rolling performance across similar installations.
