The Mastercraft bifold door system utilizes a track and bracket mechanism for installation. The system includes components such as pivot pins, guides, tracks, brackets, adjusting wheels, and snuggers or slide guides. Installation involves securing the track and brackets, assembling the door panels, and making adjustments for proper alignment and clearance. This document details the installation process and adjustment procedures based on the provided instructions.
Component Overview
The Mastercraft bifold door system consists of several key components, each serving a specific function in the door’s operation. These include:
- Upper Pivot Pin: Used to connect the door assembly to the overhead track.
- Lower Pivot Pin: Connects the door assembly to the lower bracket.
- Guide: Facilitates smooth movement of the door along the track. Options include a track guide or a slide guide.
- Track: The overhead rail that guides the door’s movement.
- Track Bracket: Used when installing double door systems to connect two track sections.
- Bracket: The lower support structure that receives the lower pivot pin.
- Adjusting Wheel: Allows for vertical adjustment of the door panel.
- Horizontal Adjustment Screw: Enables horizontal adjustment of the door panel.
- Snugger or Slide Guide: Used to secure the lead door end of the track or between guides in a four-door installation.
- Jamb Side: Refers to the vertical side of the door opening where the track is mounted.
Installation Procedure
The installation process involves several steps to ensure proper functionality and alignment of the bifold door system.
- Pin and Guide Installation: Gently tap the pivot pins and guide into the pre-drilled holes in the door panels.
- Track Positioning: Position the overhead track in the opening with the open side facing down and the bracket end toward the jamb. The track should be centered, allowing at least 3/4" of space between the track and the front of the opening. For double door systems, insert the track bracket into the meeting point of the two tracks and push them together, ensuring the bracket holes align with the track holes. Secure the track with pan head screws through the pre-drilled holes until snug.
- Lower Bracket Positioning: Position the lower bracket on the floor in line with the overhead track. The bracket must rest securely on the floor or carpet. Fasten the bracket to both the jamb and the floor using long flat head screws through each hole.
- Door Assembly Attachment: Place the upper pivot pin into the hole in the bracket and the guide into the track (or in the middle of the slide guide between the springs). Lift the door assembly slightly and drop the lower pin into the lower bracket slot.
- Initial Clearance Verification: Verify a 1/4" clearance between the pivot door and the jamb. For four-panel assemblies, ensure the panels are snug at the middle.
Adjustment Procedures
After installation, adjustments may be necessary to ensure smooth operation and proper alignment.
Horizontal Adjustment
- Top Adjustment: Loosen the screw in the top pivot bracket. Move the bracket toward or away from the jamb until a 1/4" clearance is achieved. Re-tighten the screw.
- Bottom Adjustment: Lift the door assembly and move the adjusting wheel toward or away from the jamb until the doors are plumb with the jamb. Then, lower the assembly into the bracket.
Vertical Adjustment
- Lifting the Assembly: Lift the door assembly slightly until the adjustment wheel clears the slot in the lower bracket.
- Wheel Rotation: Rotate the adjustment wheel to the left to raise the doors or to the right to lower them.
- Locking the Adjustment: Ensure the teeth of the adjustment wheel lock firmly into the bracket when finished.
Four-Panel Adjustments
If installing four panels, access to the adjustment screws may require folding or removing door panels.
Snugger/Slide Guide Installation
- Snugger Installation: Snap the snugger into the lead door end of the track.
- Slide Guide Installation: If using a slide guide, seat the lead door guide pin between the two springs in the guide.

Conclusion
The Mastercraft bifold door installation process involves securing the track and brackets, attaching the door assembly, and making necessary adjustments for proper alignment. Horizontal adjustments are made at both the top and bottom of the door, while vertical adjustments are achieved through the adjusting wheel. Proper installation and adjustment ensure smooth operation and a professional finish. The system utilizes components like pivot pins, guides, tracks, and brackets to facilitate the bifolding action.
