The craftsmanship that goes into our trolleys is unmatched, featuring years of smooth operation and dependability.
Industrial Box Rail Bypass Barn Door Hardware is intended for heavy-duty doors with a bypassing set-up. Bypassing doors can slide in front or behind one another. Similar in design to the Standard Duty Box Rail, this heavy duty bypass door hardware is available in either a soffit version for 600 lb weight limits, or a wall-mounted version for 600 lb weight limits.
The hangers in this box rail bypass door hardware kit come with a zinc apron (powder coated, if applicable) that clasps over the top of the door. Choose between a wall-mounted version, or a soffit mounted version. This heavy duty bypass door hardware is great for both interior and exterior doors.
DETERMINE KIT LENGTH:
Bypass Doors for two doors:
Soffit Mounted: For bypass doors that are soffit mounted within the opening, measure the opening width. Choose the rail size that is larger than the opening (see the "Actual Rail Lengths" chart below)--the rail can be cut onsite to exactly fit the opening size.
Wall Mounted: For some applications, bypass doors need to slide in front or behind each other and then stack on the wall next to the opening. In this case, measure the width of the doors, plus the additional width of one of the doors, since they will be stacking on top of each on the side of the opening. For example, if you have two 3'W doors, you would need a minimum of 6' of track. Of course some applications may require more track if you are trying to get the doors to cover another opening, etc. For help determining the amount of track you will need for your application, please call us.
Bypass Doors for more than two doors:
Soffit Mounted: Any amount of doors can be put on the two parallel tracks of the bypass set-up. Often, people will use three doors, putting two doors on the front track, and one door on the back track (or vice-versa). Please call for help determining the kit you will need.
Wall Mounted: Any amount of doors can be put on the two parallel tracks of the bypass set-up. Often, people will use three doors, putting two doors on the front track, and one door on the back track (or vice-versa). Please call for help determining the kit you will need.
