MOUNTING HANGER BRACKETS

NOTE:

 For wider doors, 3 hanger brackets are provided for each door.

To attach the hanger bracket, remove the screw and plastic 
bushing. Insert the plastic bushing into the hole in the glass. 
Slip the hanger bracket over the edge of the glass and align 
the hole in the hanger bracket with the hole in the glass. 
Thread in the screw to secure the hanger bracket to the 
glass. Tighten the screw.

Repeat for the other hanger brackets.

Note:

 If using obscured glass, [

] the glass panels should 

be installed with the textured surfaces of the glass to the 
exterior of the unit. The hanger brackets must be attached as 
seen in the picture to the right as the brackets will affect the 
direction of the glass when it is installed onto the header 
track.

If Hanger Brackets are loose, use 1/16" spacer to remove 
and play from the bracket.

ROLLERS SHOULD

START CENTERED

NOTE: 

The 8–32 slotted hex washer head screw used to attach 

the roller to the hanger bracket should be torqued to 25 in-lbs. 
The 1/4-20 flat head screw that attaches the hanger bracket to 
the glass should be torqued to 35 in-lbs. 

CAUTION – 

Do not over tighten the brackets and cause the end 

to clamp down on patterned glass. Do NOT use a screw gun. 
This can cause the glass panel to shatter.
