All measurements indicate the wheel diameter by the tread width.
The below capacity ranges indicate the working (dynamic) load that each caster will support. A safety factor should be included in your formula to determine your required load rating per caster.
W/(C-1)=R W is total weight needed to move. C is total number of casters required. R is ideal load rating, with safety factor built in. Divide the total load weight by one less caster than you will use to safely determine load rating.
Plate dimensions shown are overall mounting plate size.
When replacing existing casters, select the closest plate size and verify bolt-hole compatibility.
BHP = Bolt Hole Pattern, shown under each plate.
Buy American Act, DFARS US-melt requirements, and reshoring pressure have made domestic caster manufacturing a procurement priority. These 7 American-made brands cover from light institutional through extreme heavy duty. Capacity ranges, lead times, and key use cases below.
| Brand | HQ Location | Factory Lead | Capacity | Best For |
|---|---|---|---|---|
| Hamilton | Hamilton, OH | 4-6 weeks | Up to 40,000 lb | Heavy industrial, aerospace, defense |
| Albion | Spring Lake, MI | 5-7 days | Up to 12,000 lb | Heavy industrial, stainless, mold-on rubber |
| Colson | Jonesboro, AR | 3-5 days | Up to 8,000 lb | Volume manufacturing, ergonomic, tow line |
| Durastar | Mansfield, TX | 1-3 days | Up to 10,000 lb | Spring loaded, dual wheel, kingpinless |
| Shepherd | St. Louis, MO | 3-5 days | Up to 5,000 lb | Light-medium institutional, hospitality |
| P&H | USA | 1-3 days | Up to 6,000 lb | Budget industrial, value pricing |
| CasterHQ in-house | Mansfield, TX | Same / next day | Up to 16,000 lb | Stock industrial across duty classes |
All 7 brands support DFARS specialty metals clause (252.225-7008/7009) on quoted lots. Hamilton has the most comprehensive defense documentation program. Albion and Colson are widely used in defense supply chain.
All 7 qualify as US-made under Buy American Act when manufactured at their listed US locations with US-melt specialty metals. Confirm origin documentation at quote.
Section 301 tariffs and broader reshoring favor these brands over imported alternatives. Lead times on imported casters have stretched to 6-12 weeks in 2025-2026 due to tariff classification complexity.
Most large OEMs standardize on 2-3 of these brands for fleet consistency. Hamilton + Albion + Colson is the common mix for heavy industrial. Add Durastar and P&H for faster-lead stock items.
Premium brands (Hamilton, Albion) trade longer lead times for premium build and customization. Faster-lead brands (Durastar, P&H, Shepherd) trade some customization options for inventory and turn speed. Pick based on your procurement model.
