Question by: Freddie R on Sep 8, 2025, 11:33 AM

i've got 44.5 mm line to clamp up, is this the right size or do i need to convert it to inches first?

Answer by: Customer Support on Sep 9, 2025, 9:28 PM

For this clamp, 44.5 mm is the size it is meant to fit. If you ever need to compare to an inch callout, the note provided is mm size x 0.03937 = inch size.
