The fitting is part of the choice
Read the model dimensions and supplied drop together. An extension stem changes the finished blade height and is offered only for the motors listed with it. The planner rejects combinations below its stated clearance check, but it does not confirm structural support or compliance for an installation. Final suitability and electrical work need to be assessed by an appropriate installer.
Before confirming
Fans, controls and stems appear as separate quantities in the basket. Prices, delivery and any welcome reduction are shown in US dollars before submission. Review the full schedule of objects and fittings, and keep the order reference for later enquiries. That reference identifies the products selected, not an installation booking or dispatch confirmation.
