M4 Knick recommends that all Sensogate retractable holders undergo routine maintenance and cleaning at least once per year, depending on the process. To make this process as simple as possible, we are asking you to complete this form.
Maintenance and cleaning typically takes one week (including shipping) but we are happy to make accommodations to fit your schedule.
