How to Choose

1. Confirm Plate Pattern Match

Measure your existing equipment plate bolt-hole pattern with calipers. The 2-1/2″ x 3-5/8″ plate uses a 1-3/4″ x 2-13/16″ bolt pattern. Replacement casters must match BOTH the overall plate dimensions AND the bolt-hole spacing — even 1/16″ off prevents bolt-for-bolt install. Photograph the existing mount and email info@casterhq.com if unsure.

2. Capacity Sizing

Total cart load divided by 4 casters, plus 30% safety margin (50% for outdoor or shock applications). The 2-1/2″ x 3-5/8″ plate supports up to 300 lb per caster — that’s 1,200 lb total cart capacity at 4 casters. Match to your actual load, don’t exceed.

3. Wheel Size by Floor

Available wheel range: 3″ - 5″. Smooth concrete: smaller wheels work. Floor seams, thresholds, debris: 6″+ minimum. Outdoor or rough surfaces: 8″+ required. Larger wheels reduce push force by ~30% per 2″ diameter increase.

4. Wheel Material

Standard options for 2-1/2 x 3-5/8 plate: poly-on-iron (highest capacity, non-marking), cast iron (max capacity, marks floors), phenolic (heat-resistant), polyurethane (non-marking, quiet), pneumatic (rough terrain, shock absorption). Email info@casterhq.com with environment for material recommendation.

Engineer Tip: The 2-1/2″ x 3-5/8″ plate is a light-medium duty mounting standard. Capacity is rated at static load — for shock loads (cart hitting thresholds, expansion joints), derate by 30-50% OR specify kingpinless construction.

Frequently Asked Questions

What is a 2-1/2″ x 3-5/8″ plate caster?

A top-plate mount industrial caster sized for the 2-1/2″ x 3-5/8″ bolt pattern. Capacity up to 300 lb per caster on 3″ - 5″ wheels. The plate dimensions and bolt pattern (1-3/4″ x 2-13/16″) determine compatibility with existing equipment mounts.

What capacity does 2-1/2″ x 3-5/8″ plate casters support?

Up to 300 lb per caster at static rating. For a 4-caster cart: 1,200 lb total capacity. Always size 30% above your peak load for safety margin (50% for shock-load applications).

What wheel sizes fit this plate?

The 2-1/2″ x 3-5/8″ plate supports 3″ - 5″ wheels in standard configurations. Larger wheels require longer hub bores but the top-plate dimensions stay constant. Verify wheel-to-floor clearance after install.

How do I know if my equipment uses this plate size?

Measure your existing mount with calipers: overall plate dimensions (2-1/2″ x 3-5/8″) AND bolt-hole spacing (1-3/4″ x 2-13/16″). Both must match for bolt-for-bolt replacement. Photograph the existing caster mount and email info@casterhq.com for cross-reference verification.

What brands do you stock?

Hamilton (heaviest capacity, mil-spec), Albion (USA-made, widest selection), Faultless (economy industrial), Caster Concepts (custom-engineered, fastest lead time for non-stock), and Service Caster (light-to-medium duty). All cross-reference supported.

Steel or stainless?

Standard 2-1/2″ x 3-5/8″ casters: zinc-plated or zinc-yellow chromate steel for indoor industrial. Stainless (304 or 316) for wet, washdown, food, pharma, chemical environments. Stainless costs 2-3x more and capacity is 70-80% of equivalent steel. Specify by environment.

Does the caster ship with mounting hardware?

Industrial plate casters ship without bolts — bolt length depends on frame thickness. Standard bolt sizes for 2-1/2″ x 3-5/8″ plate: 5/16″-18 to 1/2″-13 grade 5 zinc-plated. Use 4 bolts + lock washers + nuts per caster.
