Hinge sets

There are three points for your hinge sets, which are vital for a functional bifold door. These hinge points help the different door sections to swing in and out like an accordion. The following are the hinge sets point.

  • Wall Pivot Hinge Set (PH): This hinge point is where the first pane of glass is attached to the top, middle, and bottom jamb. 
  • Intermediate Carrier Set (CS): Just as the name implies, this point is where two motioned panels at the top (head) are connected to the sill (bottom). You need one or two straight hinges for this point. 
  • End Carrier Set (ECS): The end carrier set is where a moving panel’s top and bottom ends. 

Preinstallation Instructions

Before installation, you must examine the door space to be sure that it is properly leveled. 

Preparing The Frame Part

To begin the installation, you need to unbox the 

Unbox Frame

  • Remove the two jambs and astragal in the box you received. Carefully remove items from the box; unscrew all joints and keep them in a safe place. Head assembly, left and right jamb, standard sill, low-profile sill, and flush sill are the out-swing parts of the frame and sill.

Assembling Jambs To Sill

  • Arrange the outer parts of the top track (head), bottom track (sill), and the left and right jamb in a square format. Ensure to lay the frames on a clean surface. Place the edges of the frames on a wood block so that the frames can be even. 

Caution: Gently handle the wood and painted part of the frames so that no dent will occur. If the frames have flush sills, put a shim under them before screwing so that the screw holes in the sill correspond with the screw holes on the jamb frame.

  • Take turns to screw each corner, starting from one corner to the other. To ensure that you don’t scratch or dent the sill, cover the sill with tape. Correctly place the sill track’s corner to the jamb track’s corner. Put the #8 x 1/2″ screws in the exterior plate holes and screw the corners together. 

Be sure there are no gaps between the sill and jamb track corners. If there are gaps, unscrew the corners, push them close, and then screw them in again. 

Assembling The Head Track Headware

  • Proceed to join the head track when you have finished joining the sill track and the door jamb’s corner. To start, place the hardware inside the head track.  

Important: Each product has tagged boxes for easy installation and hardware configuration. You should know that configuration differs for each product; hence you must follow the drawings on the hardware box. Follow the guide on how to place the hardware boxes and place them accordingly. Ensure to understand the plan before you start. Do not put the hardware boxes together. 

Do the following after finding the box for the hinge’s point:

  1. Fix the Top Intermediate carrier and Top End Carrier before the Top Pivot hinge.
  2. Depending on the configuration, attach the Top Intermediate carrier, Top End carrier, and Top pivot into the corner of the head track. 
  • To insert the top pivot hinge into the head, loosen the two screws on the top pivot hinge. A 5/32″ and 3/16″ wrench is suitable for loosening the screws. 
  • Put the head into the track using the clamp side of the hinge away from the jamb.
  • Install the top pivot hinge into the head track.
  • To unlock the Adjustment Locking Release of the Top Pivot Hinge and head track, turn and hold it with a 1/8″ Allen wrench. 

Assembling Jambs To Head

  • To join the jamb ends to the head, place the corners of the head to the jamb. Carefully remove the foam pad attached to the jamb plate. 
  • You will use a #10 x 2″ side jamb assemble screws for the jamb plate/sill corner. Each side of the corner has four holes for screws. Screw the nails into the holes; ensure that the heads are closed before tightening them. If they are, unscrew and tighten again.

Set And Fasten The Frame

  • Check the sill opening and ensure it is placed on an even surface. Then, spread sealant on the three lines of the sill opening. For accuracy, mark the lines you will apply the sealant. 

How To Apply The Sealant On The Sill

  • On the first lines, spread the sealant 6″ from down to up of the side jamb. Spread 4-1/2″ sealant on the interior sill pan lip. 
  • Apply a 2-1/8″ sealant on the second line. Leave a 2″ gap at both ends and center. 
  • Although the third line is optional and depends on the sill support, spread a sealant on the board of the sill support or a 1/4″ on the end of the wood blocking support.
  • Measure 12″ on one side of the door space and tape it with a shim. 
  • Place wood blocks by the sill and head of the rough opening so you can properly place the frame into the door space. 
  • Carefully place the assembled sill frame in the center of the space. 
  • Use a plumb, level, and square to ensure that the frame is properly fitted in the door space before putting 3″ screws to keep the frame in position temporarily. Put the screw at the head corner of each jamb.
  • Confirm that the sill has been fitted properly and the frame is square. 
  • Drill a 1/8″ hole on the metal sill pan (if you use one) on the existing holes.
  • Apply sealant to the existing sill holes to keep the sill in position. Refrain from sealing the jamb pivot hinge holes.
  • Push the 2″ screw into the foundation of the floor’s wood. Use #10 x 2-3/4″ screws for the concrete. When you are through with screwing, clean off the dust and ensure the surface is clean. 
  • Be sure that the frame in the door space is even and not bent or tilted to one side. 
  • Make the reveal between the frame and the door opening by 3/8″ on each side of the jamb. Use #8 x 3″ screws to fasten the existing holes on the jamb. Be sure that the jamb is leveled correctly. This is to tighten and keep the jamb in position. 
  • To tighten the head, consider the height of the frame when you open it. Place a measuring tape from the beginning of the frame to the edge to measure the frame. Put a shim in the head track to maintain the height. You will start screwing from the middle of the head using a #8 x 3″ screw. The existing holes may be difficult to see, but you can use a flashlight for easy identification. 
  • After securing the middle, shim the ends of the head track before screwing them into place. 
  • Put a shim on the gap between the door space and the jamb to close any gap between the interior and exterior parts of the head and jamb joint. 
  • Make a 1/8″ pilot hole on the interior hole of the Middle Pivot Hinge. The opening should pass through the frame to the wall’s door space. Use a #8 x 2″ to screw in the Middle Pivot Hinge Plate. 
  • Remove any strike plate on the frame.  
  • Bring out the Pivot Hinge hardware box. Identify its direction and the bottom side. 
  • Use the Allen wrench tool of 5/2″ to remove the silver screws on the Pivot Hinge plate. 
  • Put the Pivot Hinge into the sill track. Fasten it with two 1-¼ screws.
  • Make necessary adjustments, like screwing holes and checking with a level if the frame is even in the door space.
  • Cover jamb screws; use a mallet to set the covers. 

Installing Mohair For Flush And Low-Profile Sills

You need to add mohair to the door panels of a flush or low-profile sill. You need to examine the panels to know which requires the mohair. 

  • Place the mohair on the double side of the passive panel stile with a double lock. Staple the mohair in place.
  • The second location is at the stile in front of the double-point lock. Put a 1″ x 3″ mohair on the pad. Ensure to staple the sides and bottom of the mohair.
  • The third location is at the base of the astragal. Put the required mohair and trim when to fit. 

Installing Door Panel

You must follow the panel box’s configuration instructions to install the door panel successfully. 

  • If you are starting on the side of the jamb that will hinge the panel, place the panel on the top pivot hinge. Place a wood block to support the door panel. Then, insert #10 x 2″ screws into the existing holes to fasten the top and bottom hinge to the jamb and head track. 
  • Check if you have correctly fixed the door by gently swinging it. If there is an error, ensure to correct it before proceeding. You must maintain the switch and offsets hinge positions. Follow the hinge installation instructions.

How To Install Astragal

To install astragal:

  • Fixing the astragal depends on the installation instructions of the door. Place the astragal on the door edge’s panel and ensure that the top is in the correct position with the top of the panel. 
  • Open 1/8″ pilot holes into the panel and drill #8 x 2″ screws. Do the same for all the holes on the astragal panel. 
  • Installing the door lock requires following the installation guidelines on the lockbox.

 Joining The Building Wrap

  • Put tape by the side and top.
  • Put flashing tape
  • Collapse the top flap of the water-resistive barrier.
