The Zeroplus 7000 series range of door limiting stays with internal spring for reduction of shock when the door opens to it's full cycle. This is a very durable product which is manufactured to withstand windforces placed upon the door, to preserve the condition of the door under excessive opening speeds and force. They are a sound investment to protect your door against irrepairable damage when either being pushed too hard by users or blown open by strong winds. Our spring cushioned door stays can be adjusted so that the tension can be increased or decreased to suit your needs(this is the tension to check at 90 degrees/uncheck). The medium duty door limiting stay has stainless steel components with the exception of the spring and bar which are zinc plated steel.

Select grade 304 stainless steel for external applications (not marine or coastal).
