FAQs
Q: How many crimps do you need to make a full connection?
A: You typically need to make several crimps around the circumference of the pipe or downspout to evenly reduce the diameter so it fits properly into the next section.
Q: Why isn’t the pipe fitting even after crimping?
A: This usually happens when the crimps are uneven or not spaced consistently. Applying uniform crimps around the entire edge helps create a proper fit.
Q: Does this deform the shape of the downspout or pipe?
A: The multi-blade design creates shallow, controlled crimps that are intended to maintain the overall shape while allowing sections to connect securely.
