Schweiss Doors didn’t just wrap its head around heavy-duty bifold door hinges – the company went a step further and engineered a robust, user-friendly, greaseable hinge with a removable hinge pin.

The new hinge design, with grease zerks on every hinge, lets bifold door users grease hinges from the underside of the doorframe without having to go through the cumbersome process of removing the top rubber weather seal.

Schweiss Doors is the only door manufacturer to offer easily accessible greaseable door hinges for bifold and hydraulic doors that can be greased from underneath the door without removing the top weather seal.
