Product Description

How to measure the length of heat cable?

Example: Roof edge=10ft Roof gutters=10ft Downspoul=15ft

A: Roof edge = 10ft * 3 =30ft

B: Roof gutters = 10ft *1 = 10 ft

C: Downspoul = 15ft + 1 = 16 ft Total length = 30ft+10ft+16ft=56ft

NOTE: We would recommend you purchasing 60ft.This length allows for some flexibility in measurement, ensuring that you have enough cable to cover your desired area effectively.It's better to have slightly more than you need to ensure full coverage rather than risk falling short.
