🛠️ HVAC Depot Pro Tip

When replacing 70-21858-17, don't match by diameter alone. Verify these five important specifications:

24" Diameter + 3 Blades + 22° Pitch + CCW Rotation + 1/2" Bore

One parts source measures the physical diameter at approximately 23-1/2 inches, while Rheem/PROTECH distribution data lists it as a nominal 24-inch blade. This is normal enough that I would use 24" for your Shopify title and specifications while retaining the exact OEM part number as the primary fitment reference.
