FAIRFAX, Minnesota – Schweiss Doors has introduced a greaseable hinge with a removable hinge pin for its bifold and hydraulic door hinges.
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, company officials explain.
“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,” officials said in a prepared release.

I own a 44′ x 12′ Schweiss bifold autolock door with straps. I am as pleased with it now as I was when I first built my hangar in Wisconsin 16 years ago in 2002. Aside from some adversity up front — which Schweiss took care of promptly (and likely wasn’t their fault) — I haven’t had any problem with the door itself over the years. I even ordered the door with remote controls … although I rarely use them. Another customer on the field uses his remote all the time. The best advertisement I could give them is … if I was to build another hangar, it’ll have a Schweiss door … only now with greaseable hinges.
These people are honest, hard working upper Midwest types who can be trusted to take care of you should you give them your business. For the record, I am not affiliated with them in any way whatever.
