DH Caster 4" Plate Mount Rigid Caster, 700 lb, C-MHD4PNR

DH Casters Rigid Caster For Heavy Loads

DH Casters rigid caster uses a 4 inch wheel on a plate mount to support heavy carts, benches, or equipment where straight tracking is needed. The rigid design keeps movement in a straight line, which matters when guiding weight through tight aisles or down predictable paths in a shop or warehouse.

The caster belongs to the builders hardware class of plate mounted casters, so it is meant for bolting to a flat mounting plate on the equipment frame. This plate mount setup helps spread load across the mounting area, which is important when working near the stated 800lb capacity where frame distortion can cause alignment problems.

The SAP description identifies this unit as a 4 inch heavy duty rigid phenolic caster rated at 700 lbs, giving installers a clear capacity and wheel material reference for planning layout, spacing, and total cart load across multiple casters.

Key Caster Details That Support The Job

• The 4 inch wheel size keeps overall height compact while still rolling over typical shop floor seams, helping keep benches and carts at a practical working level.
• The rigid configuration means the caster does not swivel, so it tracks straight and simplifies control when pushing heavier loads in defined lanes or toward fixed workstations.
• The plate mount design from the plate mount product class is intended to bolt against a flat surface, spreading load over the plate area and helping the frame resist twisting under heavy weight.
• The phenolic wheel, specified in the SAP description, offers a hard rolling surface that resists flattening under load, which helps maintain consistent rolling effort at the stated capacity.
• The 700 lbs reference in the SAP description gives a clear single-caster working capacity, allowing planners to distribute weight across multiple casters for predictable support and movement.

Plate Mount Caster Setup And Fit Considerations

This DH Casters plate mounted caster is defined as a plate mount product, so it is intended to fasten by its mounting plate directly to a flat, prepared surface on a cart, bench, or machine base. That plate-mounted connection helps align the caster square to the frame, which supports straight tracking from the rigid configuration.

The 4 inch wheel diameter affects both mounting height and turning clearance at the ends of a cart or bench. Knowing the wheel size before layout planning helps align multiple casters at the same height so the load sits evenly, which reduces stress on any single caster and maintains stable rolling contact.

Using This Heavy Duty Caster In Real Work

Where A 4 Inch Phenolic Rigid Caster Fits

The DH Casters rigid caster with 4 inch wheel sits in the builders hardware category of plate mounted casters, so it is suited to applications where equipment frames are drilled or fabricated to accept a top plate. In workshops and production areas, this style of caster fits well under fixtures, tool stands, or material carts that run on reasonably smooth floors, where a 4 inch phenolic wheel can roll efficiently without needing large diameter clearance.

The wheel material is identified as phenolic in the SAP description, so it provides a hard tread that carries the specified 700 lbs rating for demanding use. This hard wheel characteristic helps when loads sit stationary for periods between moves, because the wheel is better able to retain its shape under constant load, which in turn supports consistent rolling effort when the operator starts moving again.

The manufacturers web description notes that wheel material is available in molded rubber (rubber and steel) and phenolic, which gives specifiers a choice between wheel types when matching caster behavior to floor conditions or noise expectations. Phenolic, as called out in the SAP description for this part, pairs with the heavy duty designation to support higher load focus on firm shop floors where rolling resistance and wear pattern are priorities.

Why Capacity And Build Matter For Workflow

The SAP description calls this caster heavy duty and assigns a 700 lbs reference, while the product name lists an 800lb capacity, signaling that the unit is built for substantial loads compared to light-duty utility casters. This capacity range allows equipment designers to configure multi-caster layouts that carry significant weight, such as loaded material carts or machinery bases, while staying within a clearly referenced load per caster.

The rigid configuration means steering is handled mainly by the operator guiding one or more swivel casters at the opposite end of the equipment, while this rigid caster holds the line. In practice, that straight-line tracking reduces side deflection at higher weights, which can help reduce effort when moving equipment along repeat routes.

The product description indicates the caster leg is double welded for extra strength, which reinforces the yoke where bending forces are highest when rolling heavy weight over small irregularities. This double-weld detail supports long-term geometry stability, which keeps the wheel aligned inside the yoke and helps the caster maintain smooth rolling performance over time under recurring load.

The broader web description for this caster line notes that it is sold in both broken and full box quantities, which gives shops and fabricators flexibility to order exactly the number of casters needed for a specific build, retrofit, or incremental equipment rollout without carrying excessive overstock.

Common Questions About DH Casters Rigid Caster

Selecting This Caster For Heavy Duty Mobility

The DH Casters rigid caster with 4 inch phenolic wheel and plate mount design provides a clearly identified heavy duty option within builders hardware plate mounted casters. With its 700 lbs SAP description rating and 800lb capacity reference in the product name, it supports planning for substantial static and rolling loads on shop or warehouse equipment.

The rigid layout, plate mounting style, and double welded leg described in the web text all focus on keeping motion predictable under higher weights. For projects needing straight-line control and dependable support from a compact 4 inch wheel geometry, this C-MHD4PNR caster offers the specified combination of wheel material, mounting style, and heavy duty capacity that helps align hardware selection with load and routing requirements.
