DIY Installation Steps

What You Need

Stud finder, level, drill, measuring tape, lag bolts, optional header board (2x6).

Step-by-Step

Step 1: Verify Wall Structure — Track must mount to wall studs or header board. Never mount to drywall alone — the door will fall. Step 2: Install Track — Mark level line 2-3 inches above opening. Pre-drill into studs. Secure with lag bolts (3/8 x 3 inch minimum). Step 3: Attach Rollers — Mount 3-4 inches from each end of door. Step 4: Hang Door — Place rollers on track. Install end stops and bottom guide. Step 5: Adjust — Level door, tighten hardware, install soft-close if included.

Common Mistakes to Avoid

1. Not checking for studs — Number one failure cause
2. Wrong door size — Too small leaves gaps; too large cannot open fully
3. Forgetting floor guide — Door swings and bangs without it
4. Track too short — Must clear the opening completely
5. Ignoring door weight — Heavy doors need heavy-duty hardware
