What you’ll learn
Recommended tools
- 12V Cordless Circular Saw 85mm – precise straight cuts for smaller panels
- 18V Cordless Mini Circular Saw 89mm – powerful and controlled cutting for MDF & plywood
- 18V Cordless Brushless Jigsaw – perfect for handle cut-outs and internal shapes
- 18V Cordless Brushless Combi Drill 60 Nm – for accurate drilling and secure rail installation
Step 1: Measure & calculate door size
Measure the full opening width and height. If using multiple doors, add 2–5 cm overlap to prevent visible gaps.
- Opening width: 200 cm
- Overlap: 2 cm
- Total: 202 cm
- Two doors: 202 / 2 = 101 cm each
Always subtract wheel height from total door height before cutting.
Step 2: Cut the panels
Use a circular saw for long straight cuts. Support the panel properly and cut slowly for clean edges.
For detailed shapes or recessed handles, drill a starter hole and use the 18V Brushless Jigsaw.
Step 3: Mount wheels & guides
Pre-drill mounting holes using the 18V Cordless Brushless Combi Drill 60 Nm.
- Mark wheel positions carefully
- Pre-drill pilot holes
- Mount bottom wheels securely
- Install top guides with minimal clearance
Step 4: Install the rails
Install the bottom rail first, securing it every 50 cm. Then align the top rail directly above it.
Step 5: Hang & adjust
Insert the door into the top rail first, then position the bottom wheels onto the lower rail. Start with the rear door if using multiple panels.
- Check smooth movement
- Adjust stoppers
- Verify overlap alignment
