DH Casters swivel caster is a plate mounted caster designed for medium duty applications where a 700 lb load rating is needed, so it supports heavier carts and trucks in shops, warehouses, and industrial areas without overstressing the wheel. The 4 inch wheel diameter with 2 inch tread width provides a compact profile that still rolls over typical shop floors efficiently, which helps when maneuvering loaded platform trucks and distribution carts in tight aisles. The poly / cast iron wheel construction pairs a polyurethane tread with a cast iron core, so the tread contacts the floor while the iron core carries the weight, supporting consistent rolling under rated loads. This caster is type swivel, so it rotates around a vertical axis and allows directional changes on flatbed carts and containers, which is useful when positioning equipment in confined spaces.
This medium duty plate mount swivel caster uses a 3-15/16 inch by 4-1/2 inch mounting plate, so installers can align it to common plate patterns on carts and trucks that match this footprint for a secure interface. The plate mount format offers a flat, rigid connection surface that spreads vertical and side loads into the cart frame, which helps maintain caster alignment under 700 lb rated loading. As a swivel caster, it is intended for positions where steering and rotation are needed, such as front or rear corners of platform trucks, so users can pivot and track loads through narrow warehouse aisles. The web description notes use on platform trucks, flatbed carts, containers, automotive equipment, distribution carts, and warehouse equipment, so the caster is aimed at material handling setups within those application ranges.
The web description lists applications such as platform trucks, flatbed carts, containers, automotive equipment, distribution carts, and warehouse equipment, so this caster is oriented toward material handling equipment that sees regular rolling under moderate to heavy loads. On platform trucks and flatbed carts, the 700 lb capacity and 4 inch poly / cast iron wheel help support concentrated loads while allowing operators to move goods between storage and work areas. For containers and distribution carts, the swivel design lets staff maneuver loaded units to and from staging areas and dock positions, which supports frequent repositioning during daily operations. On automotive equipment and warehouse equipment, the plate mount format and 2 inch tread width help carry machinery or parts bins where a stable rolling base is important for positioning next to vehicles, benches, or racking. In each of these uses, the caster functions as part of a multi-caster arrangement that collectively carries the total load.
The poly / cast iron wheel type combines a polyurethane tread with a cast iron core, so the tread provides the rolling surface and the core handles heavier internal stresses, which supports consistent performance at the 700 lb rating when used within typical material handling environments. The 4 inch wheel diameter affects how the caster rolls and the height it adds to equipment, so carts stay relatively low while still navigating typical floor irregularities found around warehouse equipment and automotive work areas. The 2 inch tread width increases the contact patch on the floor compared to narrower wheels, which helps carry weight on platform trucks and containers without overly concentrating force in a narrow strip. The plate size of 3-15/16 inch by 4-1/2 inch provides a defined area for mounting, so installers can align bolt patterns on cart frames to this footprint to keep casters square, which supports tracking and reduces uneven rolling. As a swivel type caster, it is well suited to positions where turning and lateral repositioning matter, so distribution carts and flatbed carts can be oriented quickly at docks, assembly lines, or storage locations.
The DH Casters swivel caster has a load capacity of 700 lb, so each caster can support that weight rating on platform trucks, carts, or equipment when designing total load support.
The C-MHD4PUS caster uses a 4 inch wheel diameter with a 2 inch tread width, which sets the rolling height and floor contact area for carts and trucks.
This caster uses a poly / cast iron wheel, meaning a polyurethane tread over a cast iron core, which combines a floor-contacting tread with an internal load-carrying core.
This 4 inch caster is a plate mount design with a 3-15/16 inch by 4-1/2 inch mounting plate, so it fastens to flat cart or truck frames using that footprint.
According to the description, this caster is used on platform trucks, flatbed carts, containers, automotive equipment, distribution carts, and warehouse equipment for material handling.
This DH Casters model is described as having no brake, so it is intended for free-rolling swivel positions on carts and equipment.
The DH Casters swivel caster with 4 inch poly / cast iron wheel and 700 lb capacity offers a plate mounted option for platform trucks, flatbed carts, containers, automotive equipment, distribution carts, and warehouse equipment where swiveling movement is needed. The 3-15/16 inch by 4-1/2 inch plate size, poly / cast iron wheel construction, and 2 inch tread width define its fit and performance on medium duty material handling builds. For projects matching these dimensions, applications, and load requirements, this C-MHD4PUS caster provides a defined specification that can be selected to match equipment design and layout.
