Plan your order & delivery
Made for your project
Confirm the shape, dimensions and quantity before purchasing. Made-to-order products cannot be returned.
Production & shipping
The current estimate is typically 2–3 weeks from the order date. Louvers generally ship by UPS; pieces too large for parcel service require LTL freight. Confirm timing and delivery arrangements for your order.
If freight is required
Use a verified commercial address with access for a 52-foot trailer. A home business is considered residential. A $275 fee applies if the carrier classifies the delivery address as residential.
Inspect at delivery
Report damage to the carrier immediately and email sales@spectis.us the same day. Notification within 24 hours is required to qualify items for a claim.
