I need to order flex and I am not sure how much to get
Measure the actual route, not a lazy loop, then ask for verification before ordering. Include size, quantity, collar/boot ends, route length, and any extra connection/waste allowance your foreman wants.
For these [count] diffusers, I measured [lengths] of [size] flex by actual route. What connection allowance or waste factor do you want before I order?
Watch out
Do not order from a ceiling guess or add random extra because you are unsure.
Check
Count each diffuser/boot and confirm flex size.
Measure actual route length from collar to boot with intended path.
Note connection ends, dampers, access, and ceiling conflicts.
Ask what allowance/waste factor the job wants before ordering.
Do not call the supplier until a foreman verifies.
