COMPLETE INSTALLATION
For fo
ur door 
congurations, mount an 
aligner as shown on the 
back side of each lead door.
For best operational 
performance and aesthetic 
appeal, install the door 
knob in the center of the 
middle rail of the lead 
door(s) (panel without 
pivot hardware). The 
knob, however, can also 
be installed in any other 
location on the lead door if 
desired. Drill a hole slightly 
smaller than the screw and 
attach knob.
Note: Unless drilling the knob attachment hole close to an edge
 on a 
hollow core door, it will likely be in a hollow part of the door. This does 
not cause problems and the door material is sufciently strong if the screw 
is snug but not over tightened.

Installation Instructions for Bifold Doors 
1. Before applying first finishing coat, lightly block sand with the grain all surfaces by hand with 400 grit sandpaper. 
Remove all handling marks, 
raise grain, scuffs, burnishes and other undesirable blemishes.
2. Clean the door with a clean, lint-free cloth, removing all dust and foreign debris. For cleaning use denatured alcohol making sure all residue is 
removed by turning the cloth often while cleaning. Allow the door to dry thoroughly.
3. Seal an un-primed door slab with a good quality water-based primer.
4. Paint all sides of the door, jamb and moulding with a good-quality exterior water-based 100% acrylic latex or solvent-based paint. Interior 
door or trim paint may be used on interior doors and interior surfaces of exterior doors. Spray applications work best. To simulate a traditional 
stile and rail door look when using a paintbrush, paint the panels first, then across all the rails from one edge of the door to the other. Then 
paint the stiles from the top of the door to the bottom. The door can also be rolled for a stipple look. For best results, apply multiple light 
coats.
