IRWIN FITNESS ROLLER J CUP 2.0 CB-4/DUFFALO BLOCKS
Irwin Fitness's Barbell Blocks, a smart and versatile solution for specialty barbell usage. Machined from solid 2.5" acetal rod, these blocks are crafted to provide a dual-purpose advantage, setting them apart from other options on the market.
Unlike many alternatives on the market, our blocks were designed to accept both 38mm and 32mm barbells.
IMPORTANT NOTICE U.S / CANADA SHIPPING
New 50% Metal Tariff (Effective Immediately)
Due to recently implemented U.S. import tariffs, all Irwin Fitness orders shipped to the United States are now subject to an additional charge.
- Approximately 70% of your total order value reflects the metal content.
- A 50% tariff is applied only to that metal portion.
- In simple terms, the tariff equals roughly 35% of your total order value.
This fee is set by the U.S. government and collected on import. We do not profit from it — it is strictly a pass-through cost.
Shipping to the U.S.
We now ship nationwide across the United States using Delivered Duty Paid (DDP) service — meaning no surprise fees on delivery.
- Flat Rate Shipping:
$650 CAD / $478 USD for LTL (less-than-truckload) shipments to U.S. terminals - Includes all broker and bond fees
- Rate applies to terminal pickup only (customers are responsible for home transport)
- Orders typically arrive at terminals faster than residential deliveries.
Residential Delivery:
Available upon request before checkout (a surcharge applies).
Customs & Documentation
We handle all brokerage through Noatum Logistics, or you may use your own U.S. Customs Broker.
For LTL shipments, an IRS or SSN number is required for clearance (not needed for UPS).
All shipments are subject to state taxes and U.S. Customs fees; Irwin Fitness does not collect or retain these charges.
Canadian Shipping
We strive to secure the best possible freight rates across Canada.
If you live in a remote or rural area, additional delivery charges may apply. You’ll be contacted before your order ships and can either approve the extra cost or receive a full refund.
To reduce costs:
- Pick up at a nearby freight terminal
- Ship to a business with a forklift or loading dock
- Offload yourself if equipped to do so

Product Info
IRWIN FITNESS ROLLER J CUP 2.0 CB-4/DUFFALO BLOCKS
Irwin Fitness's Barbell Blocks, a smart and versatile solution for specialty barbell usage. Machined from solid 2.5" acetal rod, these blocks are crafted to provide a dual-purpose advantage, setting them apart from other options on the market.
Unlike many alternatives on the market, our blocks were designed to accept both 38mm and 32mm barbells.
IMPORTANT NOTICE U.S / CANADA SHIPPING
New 50% Metal Tariff (Effective Immediately)
Due to recently implemented U.S. import tariffs, all Irwin Fitness orders shipped to the United States are now subject to an additional charge.
- Approximately 70% of your total order value reflects the metal content.
- A 50% tariff is applied only to that metal portion.
- In simple terms, the tariff equals roughly 35% of your total order value.
This fee is set by the U.S. government and collected on import. We do not profit from it — it is strictly a pass-through cost.
Shipping to the U.S.
We now ship nationwide across the United States using Delivered Duty Paid (DDP) service — meaning no surprise fees on delivery.
- Flat Rate Shipping:
$650 CAD / $478 USD for LTL (less-than-truckload) shipments to U.S. terminals - Includes all broker and bond fees
- Rate applies to terminal pickup only (customers are responsible for home transport)
- Orders typically arrive at terminals faster than residential deliveries.
Residential Delivery:
Available upon request before checkout (a surcharge applies).
Customs & Documentation
We handle all brokerage through Noatum Logistics, or you may use your own U.S. Customs Broker.
For LTL shipments, an IRS or SSN number is required for clearance (not needed for UPS).
All shipments are subject to state taxes and U.S. Customs fees; Irwin Fitness does not collect or retain these charges.
Canadian Shipping
We strive to secure the best possible freight rates across Canada.
If you live in a remote or rural area, additional delivery charges may apply. You’ll be contacted before your order ships and can either approve the extra cost or receive a full refund.
To reduce costs:
- Pick up at a nearby freight terminal
- Ship to a business with a forklift or loading dock
- Offload yourself if equipped to do so
