DH Casters rigid caster is a plate mounted caster designed for medium duty loads up to 350 lb, so it supports typical material handling carts and equipment without overbuilding the setup. The rigid design keeps movement straight, which helps control direction on platform trucks and flatbed carts where predictable tracking is more important than tight maneuvering. A 4 inch moldon rubber wheel with 2 inch tread width carries weight across the floor while spreading the load, which helps carts roll steadily under rated capacity. The plate mount design ties the caster directly into the frame, giving a broad footprint for distributing forces into the cart or equipment base. Zinc plating on the caster resists environmental exposure in normal warehouse and shop environments, so the caster keeps a consistent surface condition during repeated use.
This medium duty plate mount caster uses a 3-15/16 inch by 4-1/2 inch mounting plate, which gives installers a clear reference for matching to existing or new bolt patterns on platform trucks and carts. The wheel diameter of 4 inches sets the rolling height, so builders can align deck heights when combining this caster with other casters of the same size on multi-wheel equipment. A 2 inch tread width defines how much ground contact the wheel has, which influences how the load distributes into the floor and how the caster feels when starting and stopping a loaded cart. The rigid design means the caster holds a fixed orientation, so planning layout with rigid casters on one side and swivels on the other becomes straightforward for simple push-pull handling.
This DH Casters rigid caster is specified for platform trucks, which rely on straight tracking down aisles and loading lanes, so the rigid configuration keeps the truck moving in the intended line. Flatbed carts benefit from the 350 lb capacity because it supports typical lumber, parts, or component loads within the caster rating. Containers and automotive equipment applications use the 4 inch moldon rubber wheel and 2 inch tread width to move concentrated weight while maintaining a compact overall height, which helps keep the center of gravity closer to the ground. Distribution carts and warehouse equipment use the plate mount and defined plate size to create repeatable mounting positions across fleets of carts, which supports consistent handling characteristics from one unit to the next.
The plate mount design with a 3-15/16 inch by 4-1/2 inch plate gives fabricators a fixed mounting zone, which simplifies drilling or matching patterns when standardizing casters across different carts. The rigid type construction holds the wheel in a fixed direction, so installers can place these casters in predictable locations on frames to control how the cart tracks under load. A 4 inch wheel diameter balances clearance and stability, which helps keep equipment low enough for ergonomic loading while still rolling over minor floor irregularities common in warehouses and shops. The 2 inch tread width on the moldon rubber wheel provides a stable footprint that supports the 350 lb capacity, so carts roll with a consistent feel whether lightly loaded or near rated capacity. The moldon rubber wheel type pairs a durable core with a rubber running surface, which supports controlled rolling behavior on hard surfaces often found under platform trucks, containers, and warehouse equipment.
The C-MHD4MRR caster has a 350 lb load capacity, so it fits medium duty platform trucks, carts, and equipment within that rating.
This DH Casters rigid caster uses a 4 inch diameter wheel with a 2 inch tread width, which sets rolling height and contact area for typical carts.
The caster uses a moldon rubber wheel, combining a durable body with a rubber running surface for controlled movement on hard floors.
This caster uses a plate mount with a 3-15/16 inch by 4-1/2 inch plate, providing a defined footprint for attaching to frames.
This caster is a rigid type, so it maintains a fixed direction and suits straight line movement on platform trucks and similar carts.
The caster is specified for platform trucks, flatbed carts, containers, automotive equipment, distribution carts, and warehouse equipment, matching typical material handling needs.
The DH Casters rigid caster with 4 inch moldon rubber wheel combines a 350 lb load capacity with a plate mount design, so it aligns well with medium duty platform trucks, flatbed carts, and warehouse equipment that need predictable straight tracking. The defined 3-15/16 inch by 4-1/2 inch plate and rigid configuration support consistent mounting layouts across fleets, which helps keep handling behavior uniform from one cart to another. Matching this caster to equipment that fits its wheel size, tread width, and rated capacity helps maintain stable movement across typical applications described for this model.
