Frequently Asked Questions
Can the outside diameter change if the wire diameter stays fixed?
Yes. Outside diameter, coil count, free length and end type can be changed around the selected wire diameter if the stress, solid height and load target remain feasible.
Are the dimensions shown in millimeters or inches?
The catalog data is stored in millimeters. The summary also gives inch conversions for quick review by US customers.
What information is needed for a quote?
Send the wire diameter, OD or ID, free length, rate or load, working travel, material, environment, quantity and drawing.
