Product at A Glance

Zero engineering provides field-proven solutions. Whenever
gaps in door seals occur, it can be difficult to make needed
adjustments using conventional gasketing. Zero’s adjustable
gasketing solves those problems with ease. Just a few turns of a
screwdriver is all it takes to tighten adjusting screws along the
length of the gasket and restore a tight seal.
