Mirrored Closet Door Installation: Special Considerations
Mirrored closet doors require additional care due to the weight and fragility of the mirror:
Weight Considerations
| Size | Weight per Panel |
|---|---|
| 24"×80" | 25–35 lbs |
| 30"×80" | 30–40 lbs |
| 36"×80" | 35–50 lbs |
Always use two people for mirrored door installation. Never lean mirrored panels against a wall — they can slide and shatter.
Track Installation for Mirrored Bypass Doors
Step 1: Mount the top track to the header. The track must be level and into solid backing (header or blocking). Use 2" screws into solid wood.
Step 2: Mount the bottom track to the floor. Align with the top track using a plumb bob or laser level.
Step 3: Hang the rear door first. Insert the top rollers into the rear track channel, then lower the bottom rollers into the bottom track.
Step 4: Hang the front door. Same process as rear door, using the front track channel.
Step 5: Adjust rollers so both doors are plumb and operate smoothly.
Step 6: Install door guides at the floor to prevent doors from swinging out.
Bifold Closet Door Installation
Step 1: Install the top track. Level is critical.
Step 2: Set the pivot pin at the hinge-side corner of the opening.
Step 3: Hang the door — engage top pivot in track, lower onto floor pivot.
Step 4: Install alignment bracket at the latch side.
Step 5: Adjust for smooth operation.
