Many in-stock orders ship within 1-2 business days, but timing varies by item. Custom, built-to-order, oversized, special-order, and supplier-direct products may need extra processing time. Free shipping applies to qualifying orders over $99 within the contiguous US. Freight items may require delivery coordination; any shipping exceptions are shown before checkout. Approved returns may be subject to a restocking fee.

Most products are covered by the manufacturer's warranty against defects. Damage from over-powering or improper installation isn't covered — we'll help coordinate any valid claim.
