DH Caster 4" Plate Mount Rigid Caster, Steel, No Brake, 300 lb, C-GD40SR

DH Casters Rigid Caster For Material Handling

DH Casters rigid caster with 4 inch steel wheel is a plate mounted caster designed for material handling, office furniture, and store fixture applications, so it supports rolling loads in environments that need predictable, straight tracking. The rigid caster design keeps the wheel fixed, which holds a straight path when moving carts or fixtures down aisles or along benches. A wheel diameter of 4 inches helps the wheel roll over typical shop floor transitions while keeping overall equipment height manageable. The 1-1/4 inch tread width focuses the load over a narrower track, which suits tight spaces where wider wheels may interfere with frames or legs. A load capacity of 300 lb rates this caster for light to medium duty carts and fixtures, giving installers a clear working range when planning total rolling capacity across multiple casters on a unit.

Key Plate Mount Caster Details For Projects

• The plate mount design on this caster provides a flat mounting interface for welding or bolting to carts and fixtures, which helps installers align multiple casters on a frame using the defined plate outline.
• A plate size of 2-3/4 x 6 inches sets the footprint for each caster, so fabricators can design corner pads or mounting flanges to that rectangle when laying out steel frames or wooden bases.
• The 4 inch steel wheel with 1-1/4 inch tread width concentrates contact on a smaller area than wider wheels, which can be useful where floor space around legs is restricted by other hardware or structure.
• A 300 lb load capacity per caster defines its working role on light duty material handling equipment, so builders can plan total load by multiplying across the number of casters supporting a cart or fixture.
• The zinc plated finish on the caster components provides a protective coating over the steel, which supports appearance and surface protection in normal indoor material handling and office furniture environments.

Plate Mount Rigid Caster Fit And Setup

This plate mount rigid caster uses a defined 2-3/4 x 6 inch mounting plate, which establishes a consistent interface for welding or bolting to a base frame when setting up carts or fixtures. The rigid configuration holds the wheel in a fixed orientation, so positioning the plate at each corner sets the rolling direction for the entire unit. A 4 inch wheel diameter influences working height, allowing builders to predict how much elevation the caster adds under cabinets, office furniture, or store fixtures. The 300 lb load capacity gives installers a numeric guide when selecting how many casters to place under a platform to support expected rolling weight in service.

Using This 4 Inch Steel Wheel Rigid Caster

Where This Plate Mounted Caster Is Applied

This rigid caster with 4 inch steel wheel is specified for material handling, office furniture, and store fixture applications, so it fits typical rolling carts, mobile desks, and movable displays used around woodworking and commercial interiors. The plate mount design aligns with fabricated steel frames or wood bases that present a flat mounting area, allowing builders to size corner pads or rails to the 2-3/4 x 6 inch plate footprint. In material handling use, the 300 lb capacity per caster supports light duty carts that must transport parts, tools, or supplies between work areas. In office furniture and store fixtures, the same capacity supports mobile bases for shelving or desks that need to reposition under load without overbuilding the support frame.

Details That Support Repeatable Mounting Results

The defined plate size of 2-3/4 x 6 inches helps fabricators drill or weld consistently, so multiple casters sit square on each corner and share the 300 lb rated load evenly in a four-caster layout. The rigid, non-swiveling design keeps each caster locked to its orientation once mounted, which helps long runs of cabinets or fixtures track straight without drift when moved along aisles. The 4 inch steel wheel diameter, combined with the 1-1/4 inch tread width, sets a predictable rolling profile that installers can factor into clearance around base trim, toe kicks, or low cross-members. The zinc plated finish over the steel construction supports a consistent surface appearance across a full set of casters, which matters where base hardware remains visible on office furniture or store fixtures.
