Installing Bypass Doors

This story shows how to install closet bypass doors.


A popular choice for closets, bypass doors need no room to swing open, but they allow access to only one side of a closet at a time. Hardware kits are available for openings of 4, 5, 6, and 8 feet. To accommodate a different opening width, simply cut a standard track with a hacksaw.

The kits are designed to work with standard 1-3/8-inch-thick interior doors. If you use thicker doors, they may interfere with each other as they slide. Thinner doors may have a wide gap between them. The combined width of the doors should equal the width of the opening plus at least 1 inch. This provides 1/2 inch of overlap between the two doors when they are closed.

Some minor variations exist among bypass door kits from different manufacturers, but they are all easy to install. Check the manufacturer's directions carefully before you start.

Prestart Checklist

About 1 hour for a pair of doors

Drill/driver, level, tape measure

Leveling the track, locating and installing hardware

Bypass door hardware kit, doors, shims

Step 1

The position of the track depends on how you plan to trim the opening. Consult the manufacturer's instructions. Screw the track to the top of the door opening. Check to make sure the track is level; shim if necessary.

Step 2

Attach the hangers to the tops of the doors. The hardware kit specifies the exact locations. Tip the doors to hook the hangers onto the track. After the doors are hanging, install the center guide on the floor to keep the doors in line.
